HBM WEBINAR SHEDS LIGHT ON FIBER BRAGG GRATING TECHNOLOGY As the use of optical sensors based on Fiber Bragg Grating (FBG) technology becomes more and more widespread, both in long term complex monitoring systems and simple short term structural testing, HBM offers some valuable information and advice in its latest webinar, which takes place on 27th April 2017. Traditionally associated with complex handling and fragility, ‘Field installations of optical structural health monitoring systems: Lessons learned over a decade’ dispels this myth and shares the dos and don’ts involved in installing systems based on FBG technology. Used to determine strain, temperature, acceleration, displacement and tilt in components, structures and in environments where conventional technologies have reached their limits, FBG technology opens the door to a range of possibilities. Also used to test structures and materials with high levels of strain, high numbers of load cycles, high electromagnetic noise or in highly explosive environments, optical sensors based on FBG technology also enable the ability to monitor the condition of large structures in harsh environments, using different types of sensors, which are connected in line over long distances and interrogated by a single instrument. Suitable for a variety of applications including, Civil Engineering, Energy, and Aerospace, to name but a few, optical products are designed to be as easy to use and understand as possible for users with limited experience. Exclusively available from the HBM Academy, this informative webinar on FBG Technology has been designed to fit in with challenging time constraints which can often make attending training courses difficult. Each webinar, which normally takes a maximum of 30 minutes, can be easily accessed at a later date or simply used as a refresher course. In addition, all registered attendees will receive a link to the webinar, via email, after the presentation. All HBM webinars are free of charge and open to anyone.

NEWS & EVENTS FULTON CELEBRATES AS 1000TH TRAINEE GAINS CITY & GUILDS CERTIFICATION Just three-and- a-half- years after their introduction, Fulton Limited – the leading heat transfer specialist – is celebrating having welcomed its 1,000th trainee onto its City & Guilds Accredited training course. The City & Guilds-certified, one-day training course was introduced by Fulton in 2013 and offers a mix of theoretical and practical operational assignments which, the company claims, bridges the gap between the more expensive courses (that can cost many thousands of pounds per employee), and cheaper, straightforward ‘toolbox’ training. Commenting for Fulton, customer services manager Jeff Byrne says: “This is a real mileston for the company. We are delighted to have welcomed Muhammad Ateeb Farooq, our 1,000th trainee, who successfully completed the course and gained the City Guilds certificate. We operate the courses throughout the UK and Republic of Ireland and at our Bristol-based manufacturing facility, which has a dedicated training room.” He goes on to say that with no two boiler systems being the same, Fulton prefers to run its training courses at customers’ own facilities, so technicians and engineers learn on the equipment they will be monitoring day-to- day. However, Fulton’s in-house facility can accommodate training for its range of electric, gas, oil and dual-fuel- fired vertical and horizontal steam boiler systems. City & Guilds certification adds value to the training courses and supports both the Safe Management of Industrial Steam and Hot water boilers Guidelines BG01 (SAFed) and INDG- 436 (HSE) regarding operation and training. The Fulton Operator Routines & Maintenance course is designed for boiler operators and covers basic day-to- day operation and monitoring; and provides employees with the knowledge required to monitor a boiler and ensure it is running efficiently and safely. It also includes training in operational procedures, daily blowdowns, and checking of water levels, alarms, etc. the course also examines the importance of correctly treated feedwater and what boiler inspectors will look for during routine insurance inspections.“We have always promoted the benefits of operator training to our customers and enjoy seeing technicians and engineers grow in confidence as they improve their knowledge.” says Jeff. Fulton’s training has proven to be invaluable to employers, with operators managing more of their own maintenance and repairs and avoiding costly call-outs that require no more than the simple flick of a switch to resolve. Jeff says “Real examples like this prove that a Fulton one-day Operator Routines & Maintenance course could potentially save the cost of many expensive and unwanted engineers’ visits.” For further information on Fulton’s City & Guilds Accredited training programme, call 0117 972 3322, or email jeff.byrne@fulton.co.uk.

APPLICATIONS Qdos PUMP REPLACES THREE DIAPHRAGM PUMPS AT MAJOR WATER TREATMENT PLANT · Qdos 30 pump proves ideal for dosing phosphorous coagulant iron III chloride · Maintenance time and spare parts reductions help deliver rapid ROI · More Qdos applications now planned at this plant and others in the company The water treatment plant at Riepe, in the East Frisia region of Lower Saxony, has replaced three diaphragm pumps with a Qdos series peristaltic pump fromWatson-Marlow Fluid Technology Group (WMFTG). Dosing phosphorous coagulant iron III chloride for over a year, the Qdos 30 pump has not only cut capital equipment costs, but introduced significantly reduced maintenance and repair costs. The Oldenburgisch-Ostfriesischer Wasserverband (OOWV) is a regional water association in the East Frisia region of Germany that not only supplies clean drinking water, but purifies the waste water from more than 500,000 people through 46 water treatment plants. “Besides household waste water, we also have a relatively large amount of waste water from industrial areas,” explains Plant Manager Klaus Janssen. “For this reason, the phosphorous levels in the inflow water are relatively high, at around 15 mg/l on average. However, our prescribed phosphorous limit at the point of entry is 2.0 mg/l, although we are in fact striving to not exceed the target limit of 0.5 mg/l.” DIAPHRAGM PUMP ISSUES In order to achieve this reduction, the waste water facility uses chemical coagulation, which converts the phosphate solution in the water into insoluble phosphate compounds that can then be isolated. At Riepe, one diaphragm pump supplied the coagulant from underground storage containers into the holding tank, with the actual dosing handled by two further diaphragm pumps – one in constant use and one in standby mode in the event of a failure. Indeed, failure was an increasingly common outcome as the pump diaphragms were often corroded by the chemical coagulants, making replacement necessary. “The diaphragm pumps also produce a strongly pulsating flow which, after some time, would lead to signs of wear and tear on the fittings and valves,” says Mr Janssen. “The maintenance work started amounting to several hours per month; moreover, we had to hold a whole range of spare parts in stock, including diaphragms and valves.” A further problem with the diaphragm pumps was suction. Air would be drawn in, which could jam the valves meaning that the diaphragm pumps were unable to prime and pump. As a result, the phosphorous limits discharged from the plant increased and, in the worst case, meant that the relevant authorities had to be notified. To avoid this, emergency operations at night or during the weekend were becoming more frequent. The problem occurred most often whenever the stock of coagulant was replenished. Here, the chemical dosing lines had to be manually flooded with water to enable the diaphragm pumps to operate. HIGH PHOSPHATE LEVELS? NO PROBLEM The new Qdos 30 peristaltic pump at this site doses at 150ml/min, although it offers a maximum flow rate of 500ml/min – more than enough for occasions when there are high phosphate levels in the water. The single Qdos pump is able to draw the iron III chloride directly from the storage tank, which means that a holding pump, the standby pump and, the holding tank, plus associated float switches and electronics, are no longer necessary.“While the accuracy of the diaphragm pumps declined over time as the diaphragms became corroded and worn, the Qdos pump is extremely accurate, so we’ve able to reduce the frequency of recalibration.” COMPLETE RELIABILITY In total, Mr Janssen estimates that the Qdos pump has led to an impressive time saving of between two and five hours per month. “By relieving us of this workload and the saving on spare parts, the investment has paid off very quickly.” For more information please contact Watson-Marlow Fluid Technology Group, Falmouth, Cornwall.

GOODLIGHT T8 LED TUBES PAYBACK IN 8-MONTHS FOR QUORN FOODS

LED Eco Lights recently announced that Quorn Foods, a leader in meat alternative produce, has replaced the fluorescent tubes at its 13,000 sq. ft. Stokesley, North Yorkshire manufacturing site with high-performance, energy efficient T8 LED tubes from the Goodlight™ range. Quorn Foods achieved a payback on the installation of the Goodlight T8 LED tubes in just eight months, significantly reducing their carbon footprint. The Stokesley site is its principal manufacturing site with six hundred staff operating four production lines that create Quorn’s well known range of healthy meat free foods. Commenting, Derek Passmore, Electrical Engineer at Quorn said, “Goodlight gave us a four-fold advantage. We’ve reduced our costs, reduced our carbon footprint, reduced the maintenance workload and improved the working environment for our staff. It’s rare to make everyone happy, but replacing fluorescent tubes with Goodlight LED light fittings has pleased management, staff and made our lives easier. It was also quick, easy and economic.” Goodlight T8 tubes draw just 22W, giving Quorn Foods a direct energy saving of 60% compared to the 55W fluorescent tubes that they replaced. On top of this, Quorn achieved significant additional energy savings from the reduction in the load on the air conditioning systems. As a food manufacturing site, Quorn Foods needs to maintain the temperature on the production floor at a consistent 10 degrees C. Even when the outside temperature is below this figure, the heat generated by the machinery and the lighting means that air-conditioning is required. Installing the Goodlight LED tubes was simplicity itself, according to Derek Passmore. For more information contact LED Eco Lights Ltd, Camberley, Surrey Tel: 01276 691230.

SECURITON ASD UNITS FROM PATOL ARE KEEPING GRESSINGHAM FOODS SAFE IN DISS Gressingham Foods, which is famous for its Gressingham Duck, is now protected from fire by aspirating smoke detectors from Patol. Patol was appointed official UK distributor for Securiton aspirating smoke detection equipment in 2015 and ten units supplied by electrical wholesaler Rexel WF Senate were recently fitted at the Gressingham Foods facility in Diss by local engineering company, E Rand & Sons Ltd. Gressingham Foods has over 20 different farm sites. The new facility at Diss includes a pallet racking warehouse, several cold rooms and a packing area. In each of these locations, the units, which are among the most reliable early warning systems, were all installed with filter boxes and dirt trap boxes. Of the ten Securiton devices supplied, seven were ASD 535-1 and three were 535-2 models. The cold rooms which range in temperature from minus 4° to minus 22° Centigrade are fitted with heated sampling points to prevent the build-up of ice affecting the system. If a sampling pipe is affected by low ambient temperatures to the point where accumulating ice crystals might impact adversely upon its performance, the heating automatically comes on to immediately eliminate the problem. Developed in Switzerland and manufactured in Germany, aspirating smoke detectors from Patol are among the most precise early detection systems for fire. Impressing with their unrivalled performance level and very long service life, they are particularly reliable and robust and - thanks to their sophisticated detection technology - they can give a highly sensitive and early reaction to incipient fire conditions. Patol offers a comprehensive range of three different Securiton detectors that makes this early detection of fires both scalable and cost-effective. The difference between models is the maximum area that each covers and this ranges from a single facility up to areas measuring 5,600m2. ASD 535, the flagship model for large-scale applications in four versions (1 or 2 channels, with/without smoke level indicator) is the universal device with outstanding performance characteristics for medium-sized and large monitoring areas. Its ambient temperature range reaches as low as –30°C, making it perfect for cold storage warehouses. For more information contact Patol Ltd, Reading, Berkshire.

PROCESS INDUSTRY INFORMER - MARCH / APRIL 2017


APPLICATIONS 80 GHz LEVEL RADAR SOLUTION HELPS RECYCLE APC RESIDUE INTO CONCRETE BLOCKS Another success for high frequency contactless radar level sensors Castle Environmental is a leading supplier of specialist waste treatment, recycling and disposal services, handling in excess of 250,000 tonnes of waste each year. They operate three full permitted sites in the UK and are proud to be ISO 14001 and ISO 9002 accredited. They are dedicated to reducing reliance on landfill through the development of sustainable waste treatment and recovery methods. One type of waste processed at their Cardiff site is APCr (Air Pollution Control residue), the fine powder that remains following the cleaning of gases from Energy from Waste facilities. It contains lime which is alkaline, and consequently APCr is classified as hazardous waste. For the past 18 months Castle have used recycled APCr as an aggregate replacement in the production of precast concrete products. Following a detailed end of waste review in full consultation with Natural Resources Wales (NRW), APCr is gainfully employed in the manufacture of a range of concrete blocks. The pre-processed APCr is combined with additional aggregates and cement to produce heavy duty interlocking concrete blocks and 4” dense blocks, which are used in construction, civil engineering projects, barriers and bay walls. (See fig 1) Now that APCr can

MARCH / APRIL 2017 - PROCESS INDUSTRY INFORMER

be recycled as an alternative to landfilling the waste, the resultant concrete products mark a huge step forward in Castle Environmental’s plans to be the leading recycler of APCr in the UK. Part of this recycling process involves mixing the APCr powder with recycled water in a 4m high agitated vessel to form a slurry which is then dewatered prior to combining with other aggregates to form the blocks. During this mixing process, the level in the vessel requires careful monitoring and control to ensure the process is carried out under the correct conditions. Inside the vessel there is a very agitated surface, solids can build up on the walls as well as the agitator itself and surface foam can also be produced under certain conditions. (See fig 2) All these difficult conditions; the uneven surface, foam and solids build up - are accommodated by the VEGAPULS 64’s 80 GHz radar technology to deliver accurate and reliable level readings. It Figure 2 Challenging conditions - the mixing process employs focusing to avoid produces a very turbulent surface, splashing, surface unwanted interfering foam, build up on the walls and vessel internals signals combined with high sensitivity to read through condensation, sensor build up and to overcome the foaming surface. This technology is overcoming the ‘Laws of Physics’ that imply the higher the frequency, the more it can be affected. Through latest generation components, enhanced design and software it is taking sensitivity to astonishing performance levels, VEGAPULS 64 radar copes with these challenges and many others. 80 GHz contactless radar is offering new solutions to level measurements that were previously thought impossible with a contactless device. As well as handling difficult conditions such as these, they are also capable of measuring very low reflectivity hydrocarbons, even liquid gases, highly pure solvents, past complicated vessel internals, down long nozzles and even operating through process isolation valves.

USING

SCADA DATA

FOR IIOT JUST BECAME

MUCH EASIER At times it seems hard to believe we’re already in the second decade of the 21 st century; what is even harder to believe is that the majority of manufacturers are still only using technology that is at least 30 years old. Many of these systems work wonderfully for what they are meant to do, collect and store data and monitor systems. However, these systems alone cannot help industrial companies meet the challenges of today’s global market.

A

lthough there are several reasons for this situation, the perception that change is too difficult and expensive is the leading cause for companies to remain hesitant to take advantage of the new opportunities promised by the Industrial Internet of Things (IIoT). A recent LNS Research survey of over 400 manufacturing executives showed the vast majority of companies do not have plans to invest in IIoT technology in the near future. When we consider how expensive many of the existing systems are, it’s understandable why industrial companies are reluctant to invest in new technology. Unfortunately, these executives are often looking at old technologies that have been tweaked to try to take advantage of IIoT opportunities and may require removing the current systems. The good news is there are very affordable technologies developed specifically for the Internet Age that work with existing systems to help manufacturers gain deep insight into process behaviour that translates into fast ROI.

SCADA INFORMATION IS MORE VALUABLE THAN EVER SCADA systems were originally designed to collect data and monitor processes. Since they generate such enormous amounts of data, historians were added to store this data. Initially, historians were used to fulfill regulatory requirements, such as generating reports for government agencies. Leading industrial companies recognized the data hidden in their historians could provide valuable information on plant processes and production, but accessing and utilizing the data could be very difficult. The reason for this is historians weren’t designed for “read” purposes or a two-way transfer of information. Manufacturing execution systems (MES) were introduced in the early 1990s in an attempt to bridge the gap between plant floor SCADA systems and enterprise ERP software. They also promised to provide analytics, such as KPI data, to improve plant floor operations. While they have been able to provide more advanced capabilities than SCADA systems, they are expensive and often require extensive engineering to be implemented. Moreover, they were developed for a different business era in which systems were still largely siloed and Internet optimization was largely an afterthought.

Modular, on-demand subscription software built for the 21st Century offers economical predictive process analytics to improve efficiencies. By Bert Baeck, CEO, TrendMiner

21ST CENTURY TECHNOLOGY HAS ARRIVED When we consider the amount of time and money industrial companies have spent for traditional software, we can understand the reluctance of some manufacturers to enhance their systems. They are still trapped in the fear that any new solution will be expensive as well as require extensive engineering and training for employees. In addition, they are apprehensive about becoming locked into a cycle of difficult and expensive upgrades, patches and limited scalability. To really take advantage of the IIoT companies need next generation solutions that were developed for that purpose. These solutions are able to offer users the best of new technologies, particularly in terms of ease of use and affordability.

GOOGLE FOR INDUSTRY As mentioned earlier, while historians hold a wealth of valuable data for improving operations, accessing that data and turning it into actionable information has been time consuming and difficult. Many applications were based on data modelling, which required extensive engineering and data scientists to perform. As a result, only mission critical applications were targeted, leaving vast areas of improvement opportunities hidden. In 2008, engineers from Covestro (then known as Bayer MaterialScience) knew there had to be a better way to leverage time-series data. They worked with different types of analytics models and identified their limitations for scaling-up beyond pilot projects. Eventually, they were able to use their deep knowledge of process operations to create “pattern search-based discovery and predictive-style process analytics” developed for the average user. The unique multi-dimensional search capabilities of this platform enable users to find precise information quickly and easily, without expensive modelling projects and data scientists.

Figure 1: Combining live data with historical context shortens the analysis latency to immediate, providing an opportunity to take actions even before an event can affect process performance. A simple example of how this works is the song title recognition app Shazam. While the technology used by Shazam is different, the concept is similar. Instead of trying to map every note in a song to its vast database of songs, Shazam uses pattern recognition software that seeks “high energy content” or the most unique features of a song then matches it to

similar patterns in its database. This is a very simple explanation of a complex process, but the important thing is that it enables users to quickly find a song title with a very high rate of accuracy. Naturally, industry demands more sophisticated algorithms that are capable of going beyond mere search. Often called Google for Industry, this software works by connecting to existing historian databases then implementing a column store database layer for an index. This software makes it easy to find, filter, overlay and compare interesting time periods to search through batches or continuous processes. Moreover, this next generation solution enables users to search for particular operating regimes, process drifts, operator actions, process instabilities or oscillations. By combining these advanced search patterns users unlock the true information they need. For example, an operator compares multiple data layers or time periods to discover which sensors are more or less deviating from the baseline then make adjustments to improve production efficiency

BRINGING IT ALL TOGETHER In addition to easy search, this new technology provides process data contextualization and predictive analytics capabilities. Engineers and operators can provide annotation to provide greater insight. Its predictive analytics capabilities enable an early warning detection of abnormal and undesirable process events by comparing saved historical patterns with live process data. Moreover, the solution calculates the possible trajectories of the process and predicts process variables and behaviour before it happens. This gives operators the ability to see if recent process changes match the expected process behaviour and pro-actively adjust settings when it does not.

21ST CENTURY BUSINESS MODEL This free predictive process analytics (discovery and predictive) also employs a modern business model: online subscription pricing. In addition to making process analytics affordable to all companies, this also frees businesses from having to spend the time and money on adding additional licenses and upgrades. Each time a user logs in, they automatically get the latest version of the software. As we have seen, companies now have the option to enhance the value of the investment they have made in high quality historians. Low cost predictive analytics solutions that complement their existing historians enable companies to better use the data collected by historians to provide valuable business insights. With an affordable, plug and play solution to uncover new areas for improving operation efficiencies the question becomes why more businesses aren’t using software that is created for the IIoT generation. The future is here and companies can no longer operate solely using existing systems if they want to stay competitive in this new world.

FEATURED ARTICLE

USING CREDIT CARD FRAUD DETECTION SOLUTIONS IN THE PROCESS INDUSTRIES By Sebastian Amos -GAMBICA – Sector Head, Process Instrumentation & Control

Many people reading this will have had “the call”. Today, you may receive it by text.“Have you just made a purchase for a 56” HD TV in Currys, Singapore? “Press 1 for yes. 2 for no”. Then starts the real conversation and in most cases the conclusion is validated, the card stopped and life goes on.

D

etecting fraudulent transactions is arguably the most useful use case to individuals for big data at Amex, as it is for most financial services companies. Try as they do, it’s quite difficult for fraudsters to create transactions that totally mimic real transactions in every detail, and machine learning algorithms are quite good at picking out

these anomalies (1) If you replace “Credit Card” with “Process Variable” or “Machine Status” and Fraudulent” with “Concerning”, there seems to be the possibility of merging technologies.

ANALYSIS Where are the process industries today on this potential path to better use of big data to improve the process and better manage maintenance? A recent paper from Don Rozette published in Control Global magazine (2) recognises that within most organisations, maintenance divisions are

10

“siloed” and the process team can be oblivious to the maintenance issues, thus things get fixed but no real review is done on a) why they failed and b) how can the process be changed to remove the failure. There is also recognition that 75% of assets operate on a “run to fail” basis. With more and more data available within the historians, the first analysis to be done requires assets to be classified and prioritised as a minimum requirement to focus on the 25% that cannot operate on the “run to fail”. This is a view of today. Big data and data analytics, by default will remove the silos. Big data, Industrial Internet of Things (IIoT) and Data analytics have enormous potential within the process industries and well beyond just machine management. The amount of data that can be produced by any process automation system is now at a level that simple KPI graphs and alarm systems are flooded with data and manually interpreting this is becoming near impossible. As the Industrial Internet of Things (IIoT) develops over the next 10 years, the data will continue to increase. There is, however, time on our side. The process industries tend to lag the cutting- edge technologies for two reasons. One, developers tend to wait for the systems to become stable before deploying them into an industrial context and two, the turnover of new technology is slow. New greenfield plant will take advantage as soon as it can, but brownfield upgrades, particularly in the UK, tend to be changed out only when a device fails. So, what can we learn from technology available today in other sectors and how should it be developed and deployed? Again, we can look at the technologies used in the credit card industry. Learning what’s legit, what’s shady – An extract from a report in “theconversation.com” (3) “Simply put, machine learning refers to self-improving algorithms, which are predefined processes conforming to specific rules, performed by a computer. A computer starts with a model and then trains it through trial and error. It can then make predictions such as the risks associated with a financial transaction. A machine learning algorithm for fraud detection needs to be trained first by being fed the normal transaction data of lots and lots of cardholders. Transaction sequences are an example of this kind of training data. A person may typically pump gas one time a week, go

grocery shopping every two weeks and so on. The algorithm learns that this is a normal transaction sequence. After this fine-tuning process, credit card transactions are run through the algorithm, ideally in real time. It then produces a probability number indicating the possibility of a transaction being fraudulent (for instance, 97%). If the fraud detection system is configured to block any transactions whose score is above, say, 95%, this assessment could immediately trigger a card rejection at the point of sale.” In summary, actual data is compared against model data and when the two show a difference, an alarm is raised. In the process industries, we do something like this already. We check temperatures and pressures. We check yields and quality. Some of this is performed in real time, some is performed in the laboratories. We have asset management systems that store data about runtime and propose maintenance cycles. We can look at machine vibration analysis, that while these can alarm and stop machines effectively, thus protecting the machine, the process and people, we still need to have the full process offline while repairs are made. Rarely do we compare a formal high definition model against the actual process, though there are some excellent examples for pipeline leak detection systems. If we can collect large quantities of data via the IIoT, and create models and learning software, as with credit card fraud, we should be able to predict failure and address it before the process shuts down. Process management is now entering the world of automated data forensic analysis. The benefits here can be enormous. Oil rig shutdown can cost between $1m and $5m per day in lost production. Black starting a rig can take 3 days. Recalls on products from soap powder to pharmaceuticals can be reduced as the products would not have left the factory. So, what are the nuances in the process we can use big data for. As examples, we would be able to see when valves start to stick, not necessarily due to valve alarms but measurements taken around the area the valve is installed. We could be looking at flows, temperatures and pressures, with the self-educating software flagging a process error that would provide a focus for detailed examinations. The possibilities are endless.

PROCESS INDUSTRY INFORMER - MARCH / APRIL 2017


HOW MUCH DATA ARE WE TALKING ABOUT? It takes a lot of computing power to churn through this volume of data. For instance, PayPal processes more than 1.1 petabytes of data for 169 million customer accounts at any given moment. This abundance of data – one petabyte, for instance, is more than 200,000 DVDs’ worth – has a positive influence on the algorithms’ machine learning, but can also be a burden on an organization’s computing infrastructure. (3) We can compare this to a real-time process control system. A 10,000 I/O HART enabled system could generate 50,000 data points/second which include some locally derived information plus timestamps. Assuming each point is 512 bytes, this equates to 2.2 Terabytes per day. Currently we rarely store that level of data as historians tend to look at max/min/avg over predefined timescales, but that has always been the way around too much data. We are now approaching data storage and processing capabilities, outside of the financial capabilities of all but the largest organisations. IIoT and Big Data processing now need to look elsewhere and cloud computing is the current solution. Data needs to be stored and analysed and only the results piped back to the users.

HOW CLOUD COMPUTING WORKS The following summarises an article from “How Stuff Works” (4) Currently, nearly every office based employee in an organisation requires a computer complete with Operating System and applications to perform their job. This is, for example, Windows, Office Suite with email, Internet Access and specific programmes to enable the job to be done. This covers everything from control software development tools, finance tools, Enterprise management etc. The list goes on. This is a complex and, especially in a large organisation, an everchanging environment with serious network and security management infrastructures. Cloud computing changes the focus of where the heavy work is done with efficiencies made through virtualisation that better exploit processing power. Employees can now use basic web browsers or mobile devices to complete their tasks. How the cloud works in detail is probably not relevant for this discussion. Just assume it does.

TYPES OF CLOUD COMPUTING There are three main types of cloud computing: 1. Infrastructure as a Service (IaaS) means you're buying access to raw computing hardware over the Net, such as servers or storage. Since you buy what you need and pay-as- you-go, this is often referred to as utility computing. Ordinary web hosting is a simple example of IaaS: you pay a company serve up files for your website from their servers. 2. Software as a Service (SaaS) means you use a complete application running on someone else’s system. Web-based email and Google Documents are perhaps the best-known examples. 3. Platform as a Service (PaaS) means you develop applications using Web- based tools so they run on systems software and hardware provided by another company. So, for example, you might develop your own ecommerce website but have the whole thing, including

the shopping cart, checkout, and payment mechanism running on a merchant’s server. App Cloud (fro salesforce.com) and the Google App Engine are examples of PaaS.” PaaS lends itself to the requirements of Big Data analysis in the Process Industries.

PROS - Lower upfront costs and reduced infrastructure costs. - Easy to grow your applications. - Scale up or down at short notice. - Only pay for what you use. - Everything managed under SLAs. - No more slow internet on a Monday Morning as upgrades are sent to ever machine. - Overall environmental benefit (lower carbon emissions) of many user efficiently sharing large systems. (But see the box below.)

CONS - Higher ongoing operating costs. Could cloud systems work out more expensive? - Greater dependency on service providers. Can you get problems resolved quickly, even with SLAs? - Risk of being locked into proprietary or vendor-recommended systems? How easily can you migrate to another system or service provider if you need to? - What happens if your supplier suddenly decides to stop supporting a product or system you’ve come to depend on? - Potential privacy and security risks of putting valuable data on someone else’s system in an unknown location? - If lots of people migrate to the cloud, where they’re no longer free to develop neat and whizzy new things, what does that imply for the future development of the Internet? - Dependency on a reliable Internet connection.

WHERE ARE WE TODAY? The large computing based organisations all offer cloud services. Microsoft (5) , IBM (6) and Oracle (7) lead the way, however, the data analysis tools available are still mainly focused on supply chain management, CRMs and building services. Whilst IBM and Oracle have products with a consumer focus, Microsoft does have examples of configuration on its Azure platform for predictive maintenance(5). The focus for the Process Industries is therefore Platform as a Service (PaaS) but the focus moves to the applications that can help us. We started this article looking at the low hanging fruit benefits of big data, cloud computing and learning analytics within the maintenance sectors. There are products available that are using these technologies already. Microsoft has a complex system which can be reviewed – see Ref 8. However, there are offerings from SMEs that could be considered closer to the end user. Based on a technology generically called “Prognostics” - An engineering discipline focused on predicting the time at which a system or a component will no longer perform its intended function (9). Solutions such as Prognosys TM from Senseye (10) and Cassantec (11) use machine learning and advanced analytics extracting data from multiple sources to achieve this. The actual analytics tend to be the domain of the latest breed of Data Scientists.

MARCH / APRIL 2017 - PROCESS INDUSTRY INFORMER

These solutions, including the Microsoft offering, have a focus on identifying from historical, real-time, repair and failure histories the anticipated failure of specific items. This can work well for production lines and some process lines but it still does not reach to where it is believed/hoped that the IIoT can take the process industries.

WHAT NEEDS TO BE DONE AND NEXT STEPS Firstly, we need to see beyond the uses within maintenance. The target today is as we stated at the start: - Process anomaly detection - Product continuous quality management - Self-correcting systems - Planned maintenance as part of both the process and maintenance engineers brief. We have the design tools available today, lifted from the Credit Card company structured design approach. They are still closely aligned with software analysis procedures developed by the data scientists where the picture below, borrowed from Microsoft (5) , shows it can be easily used as the basis for industrial needs. Developing this will enable the new systems to collect large quantities of data, analyse it either against models, automatically update and modify the models and then either ask predefined “sharp questions” e.g. will this system fail in the next 36 hours, or offer a heat map that simply drives the process and maintenance teams to act on potential issues before these start affecting quality and yield. None of this can be done by human review today as the data quantities are too large. However, the IIoT will be providing the data and the Data Scientists already understand the learning software applications from banking to enable the crossover. In 10 years time, there will still be alarm systems and reports but the process and management of the process will be ordered by the intelligent data crunchers operating on the cloud. To reach this aim, companies must maintain a rolling upgrade path on all their equipment and replace it as it fails with IIoT enabled hardware. IT/OT infrastructure need to be quietly upgraded to meet the higher demands for bandwidth and radio communications. Computer systems need to migrate to cloud based services A ten-year period will bring plants to a ready to go status, the application designers will have their systems ready and the two will meet.

MEET THE WINNERS

The awards focus on key areas of manufacture and supply, including innovation and achievement, energy saving, engineering excellence, customer care and employee motivation. On the night, six companies and two individuals were awarded, and a fantastic night was had by all!! TECHNICAL INNOVATION – PRODUCTS SPONSORED BY: PROCESS INDUSTRY INFORMER WINNER: SUNDYNE HMD KONTRO VAPOURVIEW®

VapourView® is a revolutionary condition monitoring instrument that broadens the scope of sealless pump technology extending its economic and environmental benefits to wider applications. Hazardous area certified, VapourView® can be applied where sensitivity to vapourisation is critical (e.g. hydrocarbon pumping). Non-invasive, VapourView® provides a real time ‘window’ on the pumped medium, signalling any significant gas content in the liquid. Subsequent remedial system changes eliminate safety risk, maximise up-time and extend the life of capital equipment. TECHNICAL INNOVATION – PROJECTS SPONSORED BY: KSB WINNER: TRIARK AODD PUMP USED IN FOAM CONCRETE APPLICATION By using an AODD pump at its heart, Triark developed a pneumatic ‘foam generator’ that was able to produce the same sort of foam that Celcon use in the factory production of its building blocks, but in a more liquid form to enable onsite mixing and pouring of lightweight foam concrete to fill landfill sink holes. Attached to the side of the cement mixer, allowing use of the on-board compressor and water tanks, appropriate volumes of water and foaming agent are drawn separately into the integral AODD Pump, which mixes them in the correct ratio to produce the pre-foaming solution. ENVIRONMENTAL CONTRIBUTION OF THE YEAR SPONSORED BY: SPP PUMPS WINNER: SIEMENS INSTALLATION OF VARIABLE SPEED DRIVES ON MARCHWOOD POWER STATION MAIN COOLING WATER PUMPS Marchwood Power Station is located near Southampton on the Solent estuary and in 2015, they contracted Siemens DF& PD to convert three mechanically throttled pump systems on the plant cooling water intake system to variable speed flow control. On completion of the project, the power station has seen significant energy savings and a dramatically improved station power output (more MW’s for the same fuel usage) based upon optimised cooling.

THE LIFETIME ACHIEVEMENT AWARD AT THE PUMP INDUSTRY AWARDS – A MAN OF DETERMINATION Brian Huxley is a qualified Training Officer, whose career started in the early 1960’s as a commercial apprentice with GLYNWED. He went on to hold several training positions, before leaving the company in 1974 to become Group Training Officer for METCOM – a Federation of Mechanical and Engineering Trades. He held that position until 1978 when he was promoted to Regional Manager. From his humble beginnings at METCOM he progressed to Regional General Manager, then Assistant Director, then Director and eventually to take on the role of Managing Director. In 1993, amongst his other roles within METCOM, Brian was also asked to take on a Trade Association which was at that time operating with a part time General Secretary and a part time Technical officer. It was from there that our

recipient began the restructuring of the BPMA. As a Director of the BPMA, he has been responsible for introducing and creating many of the services that are available to members today, such as the Buyers Guide, Newsletters, BPMA Training and the World Pump Report. In 1998 he insisted that the BPMA employed a full time Technical Director, to oversee and further develop that important aspect of the Association’s service offering. Under his Directorship the BPMA became one of the first Trade Associations to have a website and to offer membership to suppliers of the industry, something that has been copied by many others since. In 2009, in order to safeguard the interests of both members and staff, he instigated the BPMA’s transition to a limited company. Over the years, he stabilised the finances and developed a healthy balance sheet, enabling the role of BPMA Director to be passed onto his successor, Steve Schofield, in 2013. An accomplished diplomat, well known for his calm and measured approach, he is recognised throughout the UK and Europe as a true Ambassador for the UK Pump Industry. In view of this outstanding dedication, Brian is a worthy winner of this year’s PIA Lifetime Achievement Award.

SUNDYNE HMD KONTRO VAPOURVIEW® SHORTLISTED AS FINALIST FOR PUMP INDUSTRY AWARDS Sundyne is excited to announce that the VapourView® sealless pump condition monitoring instrument has been selected as a finalist for the prestigious British Pump Industry Awards in the category for Technical Innovation of the Year (Product).

FEATURED ARTICLE

THE BENEFITS OF INDUSTRY 4.0 APPLIED TO THE PROCESS INDUSTRIES Industry 4.0 is thought of by some as somewhat akin to the development of the laser. It was developed because it could be, but its real impact on the world has yet to really emerge although somehow, we all think it will be big. The laser, of course, ended up more than delivering on its initial promise – but will Industry 4.0? by Sebastian Amos - GAMBICA – Sector Head, Process Instrumentation & Control

I

t is the nature of this type of new development that inspires others to begin to discover its uses. To a purist this might appear to be the wrong way around but it is so often the way the most momentous innovations happen in reality. This is where Industry 4.0 finds itself today – arguably it is the most exciting time in its development. Industry 4.0 is a developing concept that aims to enable the manufacturing of many products to become autonomous. By this, we mean enabling the process elements and control systems to make decisions at a local level but have the data needed for these decisions available from all the individual elements via a cloud. We will discuss this later in this article. The Process Industries has a large amount of technology already available to enable this vision and there are not many steps required to realise the advantages. The ideas are best described through an illustrated walkthrough. Large chemical works are designed to have a degree of process reconfiguration to make different products or products with slightly different compositions. An example, could be a bitumen plant that can provide different blends for different applications. Avery simple example of a blending plant is shown in Fig 1. If we take this example, orders are received into an ERP system and some degree of organisation is added. Recipes are loaded to the local workstations and typically selected by the operators who know what plant and feedstock is available. A batch run then commences. Operators keep an eye on the feedstock to make sure the appropriate system is notified for re-order. The customer sends his tanker in anticipation of the product being available and once he arrives, the lorries are filled and tared. Final invoicing can now be triggered with details available from the SCADA on weights, product and QA history if required. Fig 2 shows the typical integration of systems that enable this process. Figure 2 – Integrated Systems, today. All these systems, customer ordering, feedstock ordering, scheduling, manufacturing and invoicing are currently managed through individual systems from ERP, Accounting, Control & SCADA and the main link to the outside world is email or in some cases, paper. Now, let’s look at how we could improve this process with I4.0 Firstly, all the data from the plant is now located in a cloud, so there are no local databases or islands. The cloud has data from instrumentation, drives, motors, valves, positioners and anything else that can be monitored. Fig 3 shows the cloud solution. Figure 3 – Industry 4.0 Cloud Solution. These instrumented systems are “self-aware” in that they automatically attach to the cloud and announce who they are, their software address and the data sets they can send and receive. They can also be aware of where

14

they are in that each device has a GPS locator embedded that will identify its position to be cross referenced automatically to the P& ID and AMS (Asset Management System) This data enables the cloud to have an image or model of the system and with the physical hardware also present, we have a true Cyber Physical System (CPS). The next thing to investigate is what can be done with the data. Looking upstream and downstream, the benefits of I4.0 integration can be acknowledged. 1. FEEDSTOCK ORDERING The system can automatically order feedstock. When the cloud sees the levels in a bunker or tank dropping, a supplier with whom a previous pre-order agreement has been made will also see this data. There is no reason the supplier should have his data on a different cloud. It would be beneficial that the entire supply chain sends and receives its data for the end to end process on the one cloud. Automatic ordering and scheduling of the delivery is available to the supplier. It is not difficult to see how an extension of the complete supply chain is cloud based. Supplier “A” now schedules delivery and ships the required feedstock identifying when it will arrive. The lorry with the product is tagged so that it can receive cloud data concerning delivery time, where to enter the site, automatic security recognition and which bunker/silo/tank to deliver to. The levels are replenished, the cloud is aware. Supplier “A” had been given and accepted an order, scheduled manufacture, delivered, invoiced and been paid with all this data cloud based and the relevant applications based on the cloud servers. 2. CLOUD INITIATED PRODUCTION Orders and stock levels are now in the cloud. The cloud has a model of what plant is available and can schedule production. Recipes can be sent to the local PLC/DCS controls and these will put the batch into production. Local plant control will allow for all events to be managed on the plant, reacting to alarms only. The control systems are still reporting the plant functions to maintenance systems and the cloud will be reviewing production quality against internal models. Batch data is collated and when the production system has exported the product to the output tanks, the system is ready for the next order. 3. CUSTOMER COLLECTION The cloud has all the data concerning production schedules and times. The customer can review when and where to collect it. Again, assuming the product is to be collected by lorry, the collection data and security information is loaded from the cloud into the lorry RF Tag. This could include information cloud what the lorry ETA will be. Entering the site and directions to the correct tanks are all identified by the plant and when offloading is complete, the system is ready to use the exporting tanks again. Throughout this process there has been minimal human interaction. Operators no longer need to “tweak” the system or make production choices. Their key function is to manage alarm states. The cloud automatically keeps itself stocked, manages production, arranges collection and submits (and pays) invoices. CLEARLY THERE ARE HUGE BENEFITS IN A PLANT THAT IS TRULY INTEGRATED WITH I4.0 1. The production plant is seamlessly integrated with its suppliers and customers with all data in one place and consistent. Cloud systems and communications backbones are a key focus of today’s upgrade work with the storage and communications networks now offering seamless 100% availability. 2. The plethora of third party systems are cloud based. They all use the same data. They are managed centrally and may well be maintained by third parties on a Service Level Agreement. 3. Control systems have information concerning their environment. Thus, when a component is changed and announces itself, there is no need to recalibrate or reconfigure. They sit on a truly “plug and produce” network of devices. 4. Ordering and Invoicing are fully automatic. Payments should also be. 5. Support / Backroom staff can be reduced. 6. Maintenance engineers will be more focused and the systems will enable pre- emptive maintenance calls. 7. Such a factory could be run centrally from anywhere in the world. A follow the sun would work well. 8. Local staffing would be significantly reduced. All the above add up to improved production, faster time to market and reduced costs. What’s not to like?

FLUIDS & LIQUIDS HANDLING incl. Pumps & Valves PUMPS LIMITED - A VERY BRITISH MANUFACTURER EXPORTING GLOBALLY

UK specialist pump manufacturer Flotronic Pumps Limited was founded by Lew Norris in 1981 and pioneered the air-operated, double-diaphragm ‘ONE- NUT’ pump. Flotronic’s ‘ONE-NUT’ design allows quick pump disassembly for inspection, cleaning and maintenance – delivering a massive benefit for customers in terms of reduced down-time, particularly as the pump can be inspected or maintained in line without disconnection of pipework Today it has evolved substantially from the original and is integral to an extensive range of models and deployment in a huge variety of critical process applications. These include transferring materials as diverse as adhesives, cosmetics, drinks, dyes, food stuffs, hand cream, mayonnaise, paints, petrochemicals and yoghurt as well as aggressive chemicals such as acids, MEK and Toluene. Flotronic pumps can provide constant liquid feeds and pump thin or viscous liquids. Flotronic Pumps’ products are in operation around the world. The air-operated double diaphragm pump has other advantages …… over alternative pump types include self-priming, the ability to ‘dry-run’, ease in dealing with ‘dead-heading’ and solids content. The absence of a need for electricity also makes the pumps readily portable and very safe. Flotronic Pumps and sanitary applications - Consumers rightly expect food and other hygiene-critical products to be clean and free from agents that cause disease or infection and their expectations are reflected in increasingly demanding legislation and internationally recognised accreditations Flotronic Pumps Limited might be firmly based in the UK … … but the company is seeing significant success in developing new markets overseas. Exports as a percentage of total sales rose from just 15% in 2003 to 40% in 2016. 50% of exports go to Europe - but pumps are being sold in increasing numbers across the world including the US and Canada (25%) and the Far East (8%) - with the remaining 17% distributed to the Middle East, India, South America, South Africa and Australasia.

Hydra-Cell pumps from Wanner are said to meet the challenges of flue gas scrubbing in terms of corrosion resistance and their ability to handle abrasive particulate matter. In the wake of the recent automotive emissions scandals, air pollution control has again taken ‘centre stage’. The challenge of minimizing the environmental impact of industrial processes has never been greater as mandatory emissions threshold limits are driven ever lower. Of major concern are particulate matter and toxins emanating from thermal processes. The majority of particulates can be removed effectively by gas scrubbing in its variety of forms and modern scrubbing liquids are commonly tailored to the pollutants being removed. As the scrubbing liquid is invariably recirculated, the extracted particulates can prove problematical for pumps with dynamic seals, causing premature wear and possible catastrophic failure. Being a seal-less design, Hydra-Cell pumps handle these abrasive particles with ease. Pumped liquids or slurries are 100% contained and a wide choice of pump head materials ensures even the most aggressive scrubbing liquids cause no pumping problems.

AXFLOW INTRODUCES COMPRESSOR VAPOUR RECOVERY SYSTEM FOR TANK EMPTYING AxFlow is now offering a compressor system as an alternative to centrifugal pumps for emptying liquefied gas from storage tanks, vessels and mobile tankers. Unlike pumps, which can only unload around 85% of the liquefied gas, the compressor system will easily transfer over 99% thereby enabling users to recover this potentially expensive liquid heel. The compressor system also eliminates the problem of liquefied gases boiling when centrifugal pumps are used. AxFlow’s VRS is a simple frame-mounted unit which can be used for intermittent and continuous duties. Available in mobile and static formats, the VRS is divided into two stages, liquid transfer and vapour recovery. The function of the compressor is to push the liquid from inside the tanker into the storage vessel using pressurised vapour from the storage vessel. Following this, the compressor connections are reversed using a 4-way valve to suck out any remaining vapour in the tanker and transfer it to the storage vessel. Designed specifically for liquefied gas transfer duties, the vertical piston compressor comes in single or two stage versions with air or water-cooling. Engineered to meet customer’s specific requirements the VRS enables liquid transfer or gas evacuation down to pressures of 50 millibar absolute, and is suitable for displacements of up to 212 m3/h and system pressures up to 42 bar.

FLUIDS & LIQUIDS HANDLING incl. Pumps & Valves HYBRID CAN FEATURE ENHANCES ENERGYEFFICIENCY OF LEAK-FREE MAG-DRIVE CENTRIFUGAL PUMPS The significant benefits of using magnetically driven pumps such as; zero leakage, no wastage or environmental hazards along with extended pump life with longer service intervals, are being appreciated by many end-users in the process and chemical industries. A good example of these types of pumps is the extensive range developed by M Pumps and available exclusively in the UK through pumping specialists MICHAEL SMITH ENGINEERS. The range includes; magnetically coupled centrifugal, vane, turbine and side-channel pump options which are meeting the demands of challenging applications. With technology advancing, so are demands from end-users in the process and chemical industries seeking effective pumping solutions for handling higher pressures, higher temperatures with improved energy-efficiency. In response, M Pumps has focused on improving the energy efficiency of their centrifugal pumps which led to the development of an innovative rear containment shell and now fitted as standard on their CN MAG-M Series of centrifugal process pumps. With choice of either titanium or hastelloy C inner shell, this unique patented hybrid containment shell combines the reliability and chemical resistance of a standard inner metallic shell with the strength of a carbon fibre outer shell and can be selected for applications with liquids at temperatures up to 200ยบC and system pressures up to 50 Bar. The M Pumps hybrid solution minimises magnetic losses by featuring a very thin barrier in either hastelloy or titanium. Consequently for a given duty, M Pumps hybrid technology will consume less power in operation enabling a smaller motor to be installed compared to a pump with a traditional containment shell. Additionally, the benefits of improved energy-efficiency and a more compact, space-saving solution, CN MAG-M pumps provide the important advantages of mag-drive pumps. For example, a hermitically sealed, leak-free design with no rotating seals to fail meaning reduced downtime, no crosscontamination of the pumped liquid, no wastage, no environmental hazards and improved operator safety. Close coupled versions are available which reduces possible alignment issues and minimises on-site space requirements, a choice of chemically resistant wetted materials helps to extend pump life, increase servicing. For critical applications secondary containment options are available. Thanks to their leak-free design M Pumps are particularly suited to handling toxic, flammable or other dangerous liquids. Models are available for handling capacities up to 4000 m3/ hr, differential heads up to 220 metres (single stage) and up to 700 metres (multi-stage) with system pressures up to 150 Bar.

FEATURED ARTICLE Handheld, mobile measurement of flow in closed pipe application with Pulsar Flow Pulse

THE ECHO’S STILL THE THING

– FLOW MONITORING IN OPEN CHANNELS & CLOSED PIPES

by Alistair McKinnon, Sales & Marketing Director, Pulsar Process Measurement

There are many ways of effectively measuring liquid flow. From the ubiquitous – MagFlowmeters, turbine meters, to the highly specialised – Coriolis meters, for example. This article looks at developments in ultrasonic noncontacting measurement and acoustic non-invasive flow measurement for both open channel flow, including MCERTS applications, and also in closed pipes, based on Digital Signal Processing (DSP) techniques developed specifically for the task.

B

y far the most popular automatic, continuous (full measurement range) open channel flow (OCM) measurement approach world-wide remains the use of non-contacting ultrasonic technology which, for those who aren’t familiar with it, consists of a compact transducer, usually piezo-electric, that emits a high-frequency sound pulse, inaudible to humans, which then reflects from the liquid surface and returns, the time of flight for the echo being converted to a distance. The transducer can stand alone or form a system with a control unit.

MCERTS MEASUREMENT The basic principle is a simple one, depending on the piezo-electric crystal being re- energised by the returning signal to produce a small voltage spike, a measurement being derived from the speed of sound, and the technique has been around in one form or another for decades. In practice, however, the signal processing required to accurately discriminate the signal has developed

enormously, moving from analogue to digital, and then has followed the same improvements in speed and accuracy as every other modern digital technique. High-frequency transducers are used nowadays, maximising the resolution of the measurement in these short-range applications. Depending on the manufacturer of the equipment, processing of the signal is then undertaken in the transducer itself and/or in a wall- or panel- mounted controller which provides processing and communications. All manufacturers provide a choice of controller, or, indeed, in some instances no controller, depending on the complexity of the application. A modern, high-frequency ultrasonic system provides the high accuracy demanded by accreditation protocols such as MCERTS, the Environment Agency’s emissions monitoring scheme while being easy to install and maintain and very cost-effective. Ultrasonic systems continue to represent the most accurate MCERTS approved technology on the market, for example Pulsar offer three measurement devices approved to MCERTS Class 1, depending on application. Ultrasonic measurement uses the speed of sound in the calculation, and all OCM systems compensate for changes in speed of sound due to temperature changes. The latest MCERTS standard also includes a requirement for solar radiation shields to mitigate the effect of direct sunlight on the transducer.

OTHER OPEN CHANNEL FLOW MEASUREMENT For high-accuracy, MCERTS type applications, there is another part of the equation, which is the need for a well-engineered and installed Primary Measurement Device (PMD) such as a calibrated flume or a weir. A PMD works by constricting the flow in such a way that a change in flow rate results in a calculable change in level or ‘head’, which is what we actually measure. The flume manufacturer will also supply a head to flow curve of a minimum 21 points, entered into the controller for greater accuracy. There are many other situations, for example in a canal or in an inaccessible sump, where there is no room for a PMD to be fitted. In those cases we have two options: we can derive a ‘curve’ of flow against level by measuring the flow rate using other means at various levels, and electronically recording a set point for each level within the controller. A Pulsar system will typically allow around 32 points of calibration. Alternatively, the velocity of the flow can be measured, which may be enough in some applications where all that is required is to know that water is flowing in a certain situation.

NEW FLOW VELOCITY MEASUREMENT TECHNOLOGY Traditionally, flow velocity has been measured using contacting devices, typically turbines or Doppler immersion probes, plus some other time of flight techniques. These have been highly successful but occasionally problematic, obviously potentially prone to fouling and, particularly the Doppler sensor, reliant on various conditions within the flow. New approaches such as Pulsar’s MicroFlow and MicroFlow-I offer direct non-contacting measurement of water velocity to be made. Using microwave (RADAR) technology, along with completely novel digital signal processing, a compact transducer is positioned above the flow and makes a non-contacting, time-of- flight measurement of flow velocity. A simple bracket can be used to mount the transducer at the optimum angle and multiple sensors can be used for wide channels (over 1.5m). Going back to flow measurement, of course once a flow velocity has been determined, it can be combined with level measurement to produce a flow measurement using a velocity x area calculation. This is a powerful, relatively low cost approach that does not require the civil engineering that is so often required when measuring using a flume or weir. More often used for process control than MCERTS type applications, it can nevertheless yield good results and some systems have MCERTS approval.

COMMUNICATIONS AND CALCULATIONS Once the core measurement has been made, then all other operations derive from it. Ultrasonic systems have been developed around the needs of the water/waste water industry. Over time, the number of routines and applications built into these devices as standard has multiplied, so that now it is possible to perform pretty much any typical control function – penstock control, pump control, valve management etc., directly out of the box. For communications purposes, industrial Ethernet such as Profibus and Modbus, plus other digital protocols are available along with the more usual 4-20mA and volt-free relay closures are included, depending on model. If you look at the top of the range devices, such as Pulsar’s Ultimate Controller, then more exotic options are available , such as a camera so you can literally keep an eye on the process!

NON-INVASIVE MEASUREMENT IN CLOSED PIPES For many years, the usual approach for measurement of flow in

Pulsar’s MicroFlow velocity sensor combines with an ultrasonic transducer for a velocity x area flow measurement solution

closed pipes has been the reliable and generally accurate magnetic flow (magflow) meter, and it is unlikely that will change any time soon. However, there are drawbacks. First, if a magflow can be installed from day 1 in a new installation, all well and good. If, on the other hand, flow monitoring needs to be introduced later, then there can be a significant interruption to the process and the costs associated with the design and installation of the meter. Large sizes of magflow meters can be very expensive too. And, if it is critical that an accurate measurement is made, then that may well be worth it. If, on the other hand, what you really need is a reliable and repeatable method of monitoring the process, then the latest non-invasive methods, exemplified by Pulsar’s Flow Pulse, could well be the answer. Small, clamp-on acoustic sensors including a high-output ceramic crystal, literally fixed using just a screwdriver, and operating on pipe materials including rigid plastic, stainless or mild steel or even cast iron, are producing good results where flow rates are between 0.3m/s and 10m/s. Widebore pipes of 1 metre diameter are possible and there is no intrusion into the process whatsoever, and Pulsar’s system will work with slurries through to liquids with as little as 200ppm entrained particles, the equivalent of hard water. Ultrasound is ‘fired’ through the pipe wall at 90º to the flow. The novel spread spectrum analysis technique employed by Pulsar is called RSSA (Refracted Spread Spectrum Analysis), which analyses and integrates data over a wide frequency range to derive a flow rate, which can then be output to SCADA or telemetry. The compact system is so easy to use, even mobile operations are possible with hand-held, batter powered versions of these devices. With relatively low cost per installation, this means that they can be more generally deployed within a process, so process managers can have real clarity of flow profiles within their operations.

FEATURED ARTICLE

ISO17025 If every process is only as good as the devices used to measure it, then every one of those devices needs to be as accurate as possible. The ISO17025 standard has been created to help ensure consistency in the way that equipment, including measurement instruments, is tested and calibrated in order that its accuracy can be relied upon by end users. Dr Jonathan Farrington of ABB explains more about the standard and what it means both for end users and providers of testing and calibration services.

D

espite the ISO17025 standard having been around since 1999, there is still a lot of uncertainty around who it applies to, what it means and its benefits for both end users and testing and calibration laboratories alike. The following is an attempt to cut through the confusion and explain the importance of the standard.

WHAT IS ISO17025? The main aim of calibration is to introduce a known standard against which the accuracy of a measurement can be made. For providers of calibration and testing services, it is necessary to show how that known standard As a UKAS ISO17025 accredited was itself arrived at, in order to facility, ABB’s Stonehouse provide the traceability needed laboratory is able to calibrate between the end measurement its own temperature, pressure and how it was arrived at. and electrical equipment as The purpose of ISO17025 is well as those of third parties. to introduce a recognised and verifiable level of best practice so that end users can be confident that a provider of calibration and testing services has undertaken the correct steps when calibrating their equipment.

THE STANDARD REQUIRES PROVIDERS TO BE ABLE TO PROVE: 1. That they operate and adhere to a clear set of management procedures which can be subsequently checked against in order to ensure that a test or calibration was properly carried out. Specific areas covered under this category include: - Organisation - Document control - Corrective and preventive actions - Management reviews - Internal audits 2. That they are technically competent to perform the tests and calibration they are offering. This category extends to: - Personnel, including their ability/experience in testing and calibrating specific equipment - Premises and environmental conditions - The test and calibration methods being employed - Equipment used to perform the tests/calibrations - The demonstration of measurement traceability - Sampling, handling and transportation of the equipment being tested and/or calibrated

- Assuring the quality and consistency of test and calibration results - Reporting the results

(UKAS), which operates in accordance with ISO17011:2004, a global standard governing the general requirements for accreditation bodies.

WHO AND WHAT DOES ISO17025 COVER?

WHAT DOES ISO17025 MEAN FOR END USERS?

The ISO17025 standard covers any organisation offering testing and calibration services. Its purpose is to ensure that anyone purporting to calibrate a device is competent to do so, in order to ensure the accuracy of the resulting data from their calibration process. Recognising that different laboratories often use different methods to test and calibrate a device, ISO17025 covers both standard and non- standard methods, as well as any procedures developed by the laboratories themselves. For end users, this means that as long as an organisation and its procedures have been accredited to ISO17025, they will be able to count on the credibility of the calibration and the conditions under which it was performed.

The efficiency of any industrial or utility process ultimately relies on accurate measurement. Whether the data from an instrument is used to help maximise product quality or as part of a critical safety system, it is vital that a plant operator can count on the accuracy of that device. For end users, the ISO17025 standard provides a basic level of confidence that a provider of testing and calibration services is capable of calibrating their device. The role of ISO17025 in ensuring that testing and calibration service providers are accredited to a single recognised standard offers a number of benefits. Firstly, in the event of a problem, the ability to demonstrate that they used an accredited provider will enable end users to show that they took every possible measure to ensure the accuracy of their measurement instruments. Secondly, it effectively enables end users to shop around between providers rather than being tied to a single provider, enabling them to explore different solutions for their calibration requirements.

WHEN WAS IT INTRODUCED? The current iteration of ISO17025 was introduced in 2005 in order to bring it up to date following the launch of the ISO90001:2000 quality standard. The original version was published in 1999 and replaced the ISO/IEC Guide 25 and EN 45001 standards which had previously applied to calibration and testing services to create a single standard setting down universal requirements for both management and technical competence.

WHO DOES IT APPLY TO? As mentioned above, the ISO17025 standard applies to anyone performing testing and calibration services, regardless of the number of people involved or the scale of the activities being undertaken.

WHY WAS IT INTRODUCED? Although there are recognised standard methods for testing and calibrating equipment, there is no single set that applies universally to everything. Manufacturers that also calibrate their own equipment, for example, will almost certainly operate methods that may differ both from the standard approach and those operated by other manufacturers. For this purpose, ISO17025 puts in place the required management and technical competence needed to ensure that a test or calibration result is consistent irrespective of the method used. A key part of this includes being able to demonstrate to an end customer how their equipment was calibrated and how the end calibration was arrived at.

WHAT DOES IT MEAN FOR PROVIDERS OF CALIBRATION SERVICES? ISO17025 is not a mandatory requirement but instead seeks to introduce best practice into testing and calibration services. Although it is not a mandatory requirement, ISO17025 is like any best practice standard, in that it will be used as the benchmark against which a provider of calibration services will be compared in the event of any consequences arising from an incorrectly calibrated product. As this may potentially include liability for personal injury and/or the destruction of plant leading to public injury or loss of life, the financial and reputational benefits of being accredited to the standard soon become clear. To become accredited, an organisation must have their procedures and competence inspected and ratified by a recognised accreditation body, which has itself been accredited to international standards. This last requirement, regarding accreditation to international standards, helps to ensure that an accreditation awarded in any particular country will be globally recognised as long as the organisation that awarded it was itself an accredited body. In the UK, all accreditations for testing and calibration are managed by the United Kingdom Accreditation Service

HOW CAN I CHECK WHETHER A CALIBRATION AND TESTING PROVIDER IS ACCREDITED TO ISO17025?

ABB’s flow calibration facility at Stonehouse can be used for testing and calibration of flowmeters sized from 1mm to 2.4 metres at accuracies down to ±0.1%.

Organisations offering test and calibration services in the UK that have been accredited by the United Kingdom Accreditation Service (UKAS) will be able to demonstrate a Schedule of Accreditation. The schedule features details including their UKAS laboratory number, the address of the accredited facility, the date it was issued and the types of testing and calibration that it has been accredited for.

WHAT HAPPENS IF THE ORGANISATION THAT CALIBRATED/ TESTED MY PRODUCT WAS NOT ISO17025 ACCREDITED? As mentioned previously, there is no legal requirement for testing and calibration laboratories to adopt the ISO17025 standard or to be accredited. The standard exists as a benchmark of best practice for the testing and calibration of equipment. It is not illegal to have a device calibrated or tested by a non-accredited organisation or to use it in your process. However, in the event of problems such as impaired product quality, injury or loss of life caused by a faulty instrument, it is highly likely that blame will be apportioned according to whether the parties involved took every reasonable step to avoid the situation from occurring. While a faulty or poorly calibrated instrument may not be the direct cause of the problem, its contribution to the chain of causation will almost certainly be considered. In such instances, courts and other regulatory bodies have a tendency to look towards recognised best practices as the minimum standard. This has an implication on both end users and testing and calibration organisations. For end users, there is the need to demonstrate that they did everything possible to make sure that their device was fit for duty. Where testing and calibration organisations are concerned, meanwhile, there is the requirement to demonstrate their competence. ABB in the UK operates two accredited calibration laboratories, both located at its manufacturing facility in Stonehouse, Gloucestershire. Both facilities are available for use by third parties.

CAN YOU BE SURE THAT YOUR VARIABLE SPEED DRIVES ARE RUNNING AT

MAXIMUM EFFICIENCY? While variable speed drives (VSDs) provide an important energy saving technology, Mitsubishi Electric’s Matt Handley questions how many of the installed base of drives are actually set up to run at their maximum efficiency.

E

nergy efficiency is now a prime consideration for machinery designers, plant engineers and finance directors - with a seemingly constant stream of new legislation designed to encourage industries to reduce their energy usage. As a result there are many technologies available that will now help organisations optimise their energy requirements and reduce their carbon footprints. Is all the applied technology fully optimised though? It is a frequently quoted statistic that electric motors account for 60% of UK industrial energy usage. It is equally well known that fitting a variable speed drive to control the speed of a motor can save energy – so much energy in fact, that the purchase cost is usually recouped within 16-18 months. Importantly, a variable speed drive also allows users to fit motors sized closer to their typical duty, affording further energy-saving potential.

Today there are hundreds of thousands of variable speed drives installed in countless applications across the country, saving users many thousands of pounds in energy costs. But are end users getting the most out of their variable speed drives? Are they reaping all of the energy savings that they could be? How many of these variable speed drives are actually set up to run at their maximum efficiency? It might be assumed, for example, that having fitted a variable speed drive, you have achieved your energy savings potential – end of story. The drive may certainly be optimising the speed of the motor by matching it to the requirements of the application. In high duty pump and fan applications for example, this will mean taking advantage of the inverse square law of speed to energy consumption to deliver some significant savings in energy use. However, to really deliver the maximum energy savings, variable speed drives have to be properly set up at the commissioning

could make the drive sluggish to respond to changes in the load. However, this is no longer the case, with best of breed products incorporate technologies that will eliminate the problem. For example, the FR-F800 includes our Electric’s Advanced Optimum Excitation Control technology, which automatically switches the drive between its energy saving mode and its high torque mode to best meet the requirements of the load at any given time. With this mode enabled, users can be assured that they are always achieving the optimum energy saving but without compromising performance.

AND THE SURVEY SAYS… stage; this can be as simple as activating one parameter to turn the drive intelligent energy saving mode on.

WHERE TO START LOOKING… The first area to always look at is nature of the load i.e. is it constant torque or variable torque. The drive can then be adjusted to match its output to the load, thereby maximising the available energy savings. While a drive in constant torque mode will still save energy compared to having no drive on the motor at all, optimum savings will only be achieved in variable torque mode if the connected load is a pump or fan, although it must be stated that some types of pump require the constant torque setting. This needs to be set up when the drive is installed; again this is normally as simple as adjusting one parameter. Further, many variable speed drives have specific energy-saving modes, with dedicated algorithms tailoring the profiles of the output to deliver greater optimisation. As an example, Mitsubishi Electric’s FR-F800 variable speed drive – a dedicated product aimed at pump, fan and compressor operations – offers specific energy saving modes that can achieve further energy savings up to 15% compared to standard operating modes. It also provides a number of advanced features specific to the industries relying on fans, pumps and compressors to deliver further improved performance within the application. Some users may have shied away from enabling such energy saving modes on variable speed drives, as historically they

It is also fair to say that energy optimisation is a constantly moving target. That means ongoing monitoring of energy usage is vital for identifying areas ripe for optimisation. Even more fundamental than that is the need to perform a post installation survey once a variable speed drive has been fitted. While there is a plethora of energy saving calculation tools that can make the case for fitting the drive in the first place, these tools make a variety of assumptions that may not always be accurate against real world operating conditions. While the tools certainly provide an indication of how much energy can be saved and show estimated payback times, only a detailed post installation survey can highlight real energy savings and show opportunities for

further optimisation. We can see, then, that while variable speed drives offer numerous opportunities to save energy – and are demonstrably doing so in a wide range of industries and applications – spending a little time to set up the technology correctly will deliver so much more. Hand on heart it’s impossible to tell how much more energy users could be saving if they really optimised their drives nationwide. What we have seen is that even after a VSD has been fitted, we can often increase energy efficiency by 10% or more quite easily. It also isn’t unusual to be over 10% which if you compare that figure to the relatively small gains in motor efficiency on offer by upgrading from an IE2 to IE3 motor for example, it really is substantial. The irony is that the capability is often already there, it just needs switching on.

WIRELESS PRESSURE GAUGES EMERSON INTRODUCES THE INDUSTRY’S FIRST WIRELESS PRESSURE GAUGE TO HELP PLANTS IMPROVE OPERATIONS The Rosemount™ Wireless Pressure Gauge delivers safer and more reliable readings, enabling better visibility of field changes both in the field and remotely AUSTIN, TEXAS -- Emerson Automation Solutions has introduced the industry’s first WirelessHART® pressure gauge. The Rosemount Wireless Pressure Gauge enables remote collection of field data, keeping operators updated on changing field conditions and improving personnel safety by reducing manual operator rounds and field exposure. Mechanical gauges are plagued with quality and reliability issues. These issues are commonly associated with overpressure, vibration, corrosion, extreme temperatures, and accidental damage. Additionally, mechanical gauges are unable to communicate a device status. Emerson’s new Rosemount Wireless Pressure Gauge utilizes field-proven piezoresistive sensor technology to deliver reliable pressure readings. With the flexibility to accommodate changing process conditions, the Wireless Pressure Gauge also gives up to 150X overpressure protection compared to traditional gauges, which provides for a safer field environment by using two layers of process isolation. Bourdon tube gauges have traditionally been a mainstay for taking pressure readings in the field, but are limited to visual indication of process conditions when an operator is present. Bourdon tubes also use moving parts, which can break or wear over time due to use and vibration, causing inaccurate readings or process to spill. The Wireless Pressure Gauge eliminates mechanical gauge common weak points by removing the components that inhibit the device from reporting/displaying pressure and providing up to a 10-year life, which reduces maintenance cost and time. The large 4.5-inch gauge face provides easy field visibility. “As part of our Pervasive Sensing™ portfolio, this new gauge design fundamentally changes how customers use pressure gauges by helping them make better business decisions,” said Bob Karschnia, vice president and general manager of wireless products at Emerson Automation Solutions. “Real-time insights provide actionable information that improves personnel safety while reducing facilities’ costs and time.”

FEATURED ARTICLE FOOD INDUSTRY FOCUS

GETTING TO GRIPS WITH GLYCOL:

A HIDDEN DANGER IN FOOD PROCESSING

After hygiene, p r e c i s e temperature c o n t r o l is of vital importance for the food and beverage industries; both in terms of regulating the working environment as well as specific production processes – to ensure consistent quality throughout the year. However, many manufacturers are mistakenly overlooking one element of their cooling systems which could pose a serious contamination risk when disaster strikes. Here, Brent Hall, Technical Manager at ICS Cool Energy, explores what manufacturers need to know about glycol and how they can ensure their cooling system is performing at its best and safely.

SETTING THE SCENE Glycol is a staple in all chiller-based cooling systems operating below 6˚C, and is effectively an anti-freeze solution with built-in inhibitors to prevent the heat transfer fluid from damaging chiller systems. This usually occurs from freezing, especially if the chiller is outside, or from the corrosion of internal parts. Used throughout industry in secondary refrigeration systems, glycol can be separated into two main categories: mono-ethylene glycol (MEG) and mono propylene glycol. Most food processing plants are well aware of the high toxicity levels of MEG and it is therefore rightly overlooked in favour of MPG for all food-related applications. An MPG offers low oral toxicity levels and for the last 20-30 years, it’s been perceived as the safe solution where there is a risk of incidental contact with food. In fact, MPG as a compound is actually used in some food colourings and flavourings, as well as e-cigarettes. However, MPG is fundamentally very corrosive. While it represents minimal risk to humans, an MPG, even when diluted with water, can prove to be highly corrosive when it meets metallic elements found within a chiller system, namely those made from aluminium, copper and steel. Therefore, the vast majority of suppliers recommend the use of inhibitors to counteract the corrosive nature of the glycol, and this is commonly accepted within the food and beverage processing sector.

THE HIDDEN TOXINS – CRUCIAL FACTS However, while these inhibitors are necessary to ensure the chiller system is able to operate efficiently and effectively, what’s often missed is that a lot of these commonly-used inhibitors do not offer the same levels of low toxicity as MPG.

32

Crucially, the glycol inhibitor toxicity information is frequently not reflected in the safety data sheets due to the relatively low volumes used, so they too are missed by the end-user. An uninhibited MPG and water solution would not pose a risk of poisoning if a leak were to occur and it came into contact with a product intended for human consumption. The same cannot be said, however, if the heat transfer fluid has been treated with the majority of anti- corrosion inhibitors available on the market. Ultimately, using the wrong inhibitors means the MPG solution creates a serious risk of contamination. Vitally, this fact is not known by many in the food industries.

SOLVING THE PROBLEM How can the food processing industry therefore start to tackle this potential contamination risk? Awareness is the first step. I urge all food and beverage manufacturers to check with their current glycol supplier whether the substance poses a contamination risk if it were to come into incidental contact with food. Next, consult with industry bodies. There are a number of organisations which can offer guidance on ‘food safe’ products, with the NSF being a key authority. The NSF can provide a list of products which are accredited as safe to use in food processing applications, and can therefore provide a reliable alternative to MPGs with potentially toxic inhibitors. These products, which include the NSF-accredited FlowCool-FS glycol from ICS Cool Energy, feature organic inhibitors which can guarantee the required levels of corrosion prevention and thermal efficiency, without posing a risk to human health if inadvertently consumed. These organic inhibitors have been developed by a team of skilled chemists which, when combined with an MPG, will offer end-users the desired peace of mind when it comes to avoiding potentially poisonous contamination.

PEACE OF MIND Ultimately, the food processing industry is a rightly risk-averse market sector. One small leak can cost a company its credibility and share of the market, and it is becoming increasingly hard to recover reputational damage in such a fast-paced and competitive market. Glycol is an ever-present fixture in most cooling systems in food and beverage processing plants across the country. However, many manufacturers may unwittingly be exposing themselves to serious contamination risks if a leak were to occur and the glycol used was treated with potentially harmful inhibitors. Fortunately, new products are entering the market which combine MPGs with organic inhibitors to deliver a heat transfer solution which is both reliable and, crucially, one hundred per cent safe for incidental human consumption if a leak were to occur. In an industry where there is no room for error, you can’t under estimate the importance of extra peace of mind.

5 TIPS FOR GETTING THE MOST OUT OF YOUR GLYCOL 1. ONLY USE INHIBITED GLYCOL Uninhibited glycol and water mixtures are very corrosive, often even more than plain mains water. 2. DON’T MIX GLYCOLS Different types and brands of glycol shouldn’t be mixed. Most modern glycols contain inhibitors and are dyed for identification. If accidentally mixed, incompatibilities can lead to separation and/or reaction, resulting in gel formation which will clog filters, strainers, and pump suctions. 3. CHECKING YOUR LOCAL ENVIRONMENTAL RULES Some areas have regulations regarding the use and disposal of particular glycols and antifreeze solutions, concerning things such as ground structure, the water table and drainage. Be sure to consult your local authority to check the local environmental rules. Bio- glycols are an environmentallyfriendly alternative. 4. USE THE CORRECT WATER Most systems use ordinary mains “tap” water. However, applying the appropriate inhibitors and biocide is of vital importance to prevent chiller system damage. Using one of the “Pure” waters – distilled, demineralised, de-ionised or RO Water – will remove all the unpredictability associated with town mains water. We recommend the use of pure water – distilled, demineralised, de-ionised or RO water – with a suitable (minimum 20%) inhibited glycol mix to give the ultimate system protection. 5. MAINTAIN YOUR CHILLER AND SYSTEM’S HYGIENE AND FLUID If either of the water/glycol solution or system pipework are deficient in any way, the chiller’s operation will be compromised and the heat transfer capability will be reduced. Filters/strainers should be installed and checked regularly, although the best policy is to tackle the source of any contamination. The chilled water system must be flushed, cleaned and sanitised prior to adding a new water/glycol solution. It must also be regularly sampled and tested to ensure there are no underlying or progressive contamination and/or corrosion issues.

SPECTROSCOPY THE BUZZ AROUND NANOSPONGE SERS AND TRACE-LEVEL DETECTION

OCEAN FX SPECTROMETER PROVIDES HIGH ACQUISITION SPEED

Sensitive spectroscopy tools help identify substances linked to honeybee population decline Ocean Optics has shown how highly-sensitive, trace-level Raman spectroscopy measurements can detect concentrations of insecticide that are less than a fiftieth of the level judged harmful to honeybees. Using a real-world example related to the problem of honeybee population decline, the company demonstrated the power of RAM-SERS-SP SurfaceEnhanced Raman Spectroscopy substrates’ proprietary gold-silver nanosponge alloy. By comparing the ability of new gold-silver substrates with that of traditional substrates to detect imidacloprid, an insecticide suspected to be dangerous to bee colonies, Ocean Optics scientists were able to demonstrate the enhanced sensitivity that RAM-SERS-SP substrates bring to Raman measurements. SERS substrates amplify very weak Raman signals by many orders of magnitude, with measurements of SERS-active analytes possible at even parts-per-trillion levels. Silver-only SERS substrates work best with 532 nm Raman excitation, while gold substrates are better suited to 785 nm Raman systems. By combining the silver and gold on one substrate the new SERS nanosponge substrates perform well with either wavelength. When used with 638 nm Raman excitation, the nanosponge substrates are enhanced to an even higher level of sensitivity. Recent high rates of honeybee loss have been investigated by US government regulators and other researchers. According to ongoing US Environmental Protection Agency (EPA) studies, the insecticide imidacloprid has been identified as a threat to commercial honeybee colonies, with the agency citing traces at concentration levels greater than 25 ppb as likely harmful to honeybees. To test the effectiveness of Ocean Optics substrates in detecting imidacloprid at these harmful trace levels, Ocean Optics scientists set up a lab experiment using the company’s gold nanoparticle and gold-silver nanosponge SERS substrates. They made a series of measurements using the gold nanoparticle substrates, in a setup with 785 nm Raman laser excitation, and a series of measurements using the gold-silver nanosponge substrates, in a setup with 638 nm Raman excitation. In the test, the gold-silver nanosponge SERS substrates delivered the best results, detecting imidacloprid concentrations as low as 0.4 ppb (well within the 25 ppb concentration rate cited by the EPA as harmful to bees). The substrates high sensitivity and low background noise made it easier to discern Raman peaks at these very low-concentration levels. Raman is a useful technique for fast, non-destructive analysis, with the enhanced sensitivity provided by SERS substrates allowing detection of trace levels of samples such as insecticides. Affordable and easy to use, the Ocean Optics SERS substrates are well suited to deployment in the lab or field.

Latest Ocean Optics device offers Ethernet operation, speed, sensitivity and spectral buffering The latest miniature spectrometer from Ocean Optics offers high-sensitivity CMOS detector performance, an acquisition speed of up to 3,000 scans a second and on-board spectral buffering to ensure data integrity during reaction monitoring.

FEATURED ARTICLE FOOD INDUSTRY FOCUS

IN THE PIPELINE successfully in thousands of different process applications, there are several recent innovations which provide superior temperature control, reliability and efficiency. These include:

For food manufacturers dealing with v i s c o u s products, the design and specification of appropriate pipework is crucial. Whilst jacketed pipework is familiar territory, what are the latest solutions available to minimise seepage and optimise temperature control? Stephen Forrester, MD of adi Process Pipework, provides his analysis.

TRIPLE JACKETING

V

MINIMISING SEEPAGE

iscosity plays a key role in any industrial process where liquid is involved, but it is particularly important in the food & beverage sector. For example, high volumes of liquids, ranging in viscosity from aqueous to pasty, must be carefully pumped through pipelines to ensure the quality of the product is maintained. Process pipework systems carrying viscous products must be sized correctly dependent upon the viscosity and operating pressure that needs to be achieved, to provide the appropriate flow rates to service plant items such as temperers and depositors. However, problems arise when fluctuations in temperature cause the viscosity or state of the liquid to change. Often, liquids carried in pipelines are much hotter than ambient temperature and, as such, experience heat losses if temperature control measures are not implemented. For example, concentrated sugar slurries used in confectionary production often require preventative measures to stop the formation of sugar crystals which can adversely affect seal performance in the pumps and valves. One of the most widely-used solutions in the industry is jacketed pipework. This involves is passed through to either heat or cool the liquid in the inner tube. This maintains a consistent temperature of the medium that is being transferred to ensure that a constant flow rate is achieved. While the concept of jacketed pipework is straightforward, and is used

The triple jacket system uses 316 stainless steel on the inner skin where the product is in contact with the pipe. There is a fully welded 304 stainless steel jacket over the tube, and fittings with an inlet and outlet connection which allow the flow of hot water through the jacket sections at a controlled temperature to heat the product. The triple jacketed system then has a further fully welded jacket which is filled with suitable insulation sections before welding. This design drives the heat inward, towards the product, which makes it more effective and efficient than conventional jacketing. This also means that the heat does not escape into the area and raise the ambient temperature of the building, therefore reducing the need for air conditioning. Whilst the initial cost outlay is higher than normal jacketing, the long-term energy savings provide an attractive return on investment. adi developed this system for a chocolate production installation in Poland in 2008 but this has since been rolled out across other manufacturers and contractors.

Fats in certain products often seep out of the flanged gaskets normally used such as nitrile and gortex. However, captured O-ring gasket systems are proven to prevent the seepage that often takes place. This is where a normal O-Ring, usually made of either of either Buna®-N or Fluorocarbon, is held between two aluminium retaining rings to form a vacuum seal. This is a more effective sealant than a flanged gasket as it provides a food hygiene grade encapsulated seal that has proven to be far more effective in the long-term prevention of degradation or seepage when in contact with viscous products such as sugar syrup, glycol or chocolate.

LONG RADIUS BENDS Long radius bends present a challenge to some manufacturers, as prefabricated jackets are not always available in the correct dimensions. In these instances, a bespoke solution is the best choice, however this can be costly and involve a number of different parties. Service providers such as us may also have the facilities to manufacture highly customised products which allow to incorporate long radius bends. For example, we can use long radius bends of up to three diameters for the inner bends and have also used triple jackets for pigging systems.

THE ALTERNATIVES The primary alternative to jacketed systems is trace heating. Trace heating involves running an electrical heating element – known as ‘heat tape’ - along the length of a pipe to maintain the temperature of the material within. The pipe must then be covered with a layer of thermal insulation to prevent heat loss and increase energy efficiency. With its useful thermal properties, such as the ability to transport heat over long distances while giving up its heat at a constant rate, steam offers a useful alternative to electrical heat tape in trace heating applications. Steam tracers can often use excess process steam that would otherwise go to waste, making them a highly efficient option. And in the absence of a live electrical current, steam tracing is inherently safe and suitable for use in all zones. However, the main issue with any trace heating system is the inconsistency of temperature it provides. Typical trace heating systems will generate hot spots that can bake off the product which are then compounded by cold spots in other locations. While a self- regulating tracer cable can adjust its watt output at any point along the entire length of the heater circuit, helping to prevent hot or cold spots, a triple jacketed system will still offer superior temperature consistency. As an example, we recently completed an upgrade of a trace heating system to jacketed pipework for a well-known UK biscuit manufacturer. The work involved replacing the old and expensive to use trace heated copper pipework with new stainless steel jacketed pipes and filters. Totalling 150 metres in length, the pipework feeds the syrup from the holding tanks to eight mixer facilities. The pipes were manufactured in 3m lengths at our manufacturing facility in Somerset and transported to site for installation. Since these production systems are in operation 24/7, it was crucial that there were no interruptions to the process and no bacterial issues. Therefore, all the pipework was both pressure and swab tested, with every weld undertaken by a specialist coded welder. The result was significant energy savings for the manufacturer. A costly process, which used a significant amount of electricity, was replaced with four heaters to provide a flow of hot water around the jacked pipework system. The second alternative to jacketed pipework is ‘limpet jackets’ or ‘limpet coils’. Limpet jackets offer a relatively inexpensive temperature control solution; however, as the system is not in close proximity to the product, heat transfer is inconsistent. As with trace heating, insulation is also required with limpet jackets to retain heat which is an added expense. An issue affecting both limpet jackets and trace heating systems is the inability to fully weld the insulation jackets required. Therefore, they are far more susceptible to damage, particularly when used in rugged industrial environments. Damaged insulation does not retain heat properly, meaning the product within the pipework is not maintained at the correct temperature.

POWDER CHARACTERISATION & PREDICTED PERFORMANCE FOR PROCESS DESIGNERS & ENGINEERS Predicting the performance of powder processing equipment can be a significant challenge but is vital for process designers specifying new plant. It demands a comprehensive understanding of the entire process and familiarity with the relationship between powder properties and process equipment, together with how they combine to deliver product with the intended properties and quality. This same understanding is also required by engineers working as part of the manufacturing team, who must use the specified plant to achieve optimal output.

ophisticated powder characterisation tools make it possible to predict powder behaviour within production processes and use this information to accelerate and optimise the selection of processing equipment. This article uses examples of two typical powder handling operations to illustrate this approach.

HOPPER DESIGN AND REFILLING PROTOCOLS Consider a blend flowing from a hopper into the feed frame of a tablet press, with the hopper being refilled every time the powder level falls below a certain point. With certain blends, the discharge flow becomes erratic shortly after the refill, resulting in inconsistent filling and plant stoppage. Not all blends exhibit this behaviour and analysis reveals that the material at the hopper outlet, which is already compressed by the weight of the powder bed above it, is further consolidated by vibration from surrounding machinery when the flow is paused during refilling. The powder’s response to vibration is, therefore, highly relevant and problems are more likely to arise if vibration causes a major change. Universal powder testers incorporate bulk, shear and dynamic flow measurements in a single instrument, measuring the powder in motion, and allowing the analysis of samples in a consolidated, conditioned, aerated, or even fluidised state. This enables the flow energy of a conditioned sample to be compared with that of a sample consolidated by compaction or vibration, yielding a quantifiable consolidation index (CI), and providing the necessary insight to rationalise the processing behaviour outlined above. Comparative studies of the die filling performance of two different powders, A and B, provide an illustration of this point. Sample A has a CI (tapped) of 1.11 while that of sample B is 2.32. This indicates that B, a relatively cohesive material with very fine (4 microns) angular particles, is significantly more affected by vibration than A. Die filling trials confirm that the performance of B deteriorates markedly if it is consolidated, as would be expected from the results, whereas A is likely to exhibit much more robust behaviour. A designer with access to the powder testing information has options - specify a more accommodating hopper with more steeply angled walls and/or larger outlet; pursue a policy for reducing equipment vibration; and/or install equipment for rapidly releasing a blocked hopper. This same information leads the manufacturing team to better operational practice with respect to hopper filling and an improved response in the event of blockage, with refilling the hopper with smaller quantities more frequently likely to be one of the best solutions. 36

By Tim Freeman, Freeman Technology CORRELATING POWDER PROPERTIES WITH SCREW FEEDER PERFORMANCE Process designers routinely use screw feeders to control the flow of material from hoppers. The properties of a powder will directly impact performance of the feeder and a poorly matched powder/feeder combination will typically be associated with low feed rates, high screw torques, and the accumulation of powder on the tube walls, decreasing both short and long term operating efficiency. The key screw feeder design variables that can be manipulated include: the size of the feeder (diameter and length); the geometry, drive and pitch of the auger; and the accessories used to ensure consistent flow, such as vibrational feeders and fluidisation or agitation in the feed hopper. Specifying the optimal screw feeder for a given application is critical to operational success, so characterising powders in order to predict is extremely useful. A collaborative study between Gericke AG (Zurich, Switzerland) and Freeman Technology Ltd (Tewkesbury, UK) investigated the properties of five different powders and their performance in two different types of screw feeders. The GLD is a compact, versatile feeder used for high accuracy feeding of dry solids, for pilot scale applications, and for those requiring frequent material changeover. The GZD unit is a compact, self-cleaning, twin screw extruder used for low capacity applications and is particularly suitable for materials with poor flow characteristics.

THE FIVE POWDERS TESTED WERE: - Calcium Citrate - Calcium Hydroxide - Cellulose - Maltodextrin - Milk Protein

Table 1 shows the dynamic, bulk and shear powder properties for the five powders alongside the volumetric feed rate for each powder type when run through the GLD screw feeder. Using multiple linear regression to identify correlations between these two sets of data, two dynamic flow properties were found to predict performance in the GLD feeder: Specific Energy (SE) and Flow Rate Index (FRI). SE reflects how a powder behaves when in an unconfined state and is heavily influenced by inter-particular interlocking and friction. FRI describes how a powder’s resistance to flow changes as a function of flow or shear rate.

Table 2 shows the powder properties again but now compared to volumetric feed rates when run through the GZD feeder. In this case, a simpler correlation was observed with Aerated Energy (AE) robustly predicting the actual feed rate. AE is the flow energy measured when the sample is aerated by air flowing up through it at a defined linear velocity - in this case PROCESS INDUSTRY INFORMER - MARCH / APRIL 2017


40 mm/s, hence AE40. Cohesive powders tend to have a relatively high AE, since aeration does little to reduce the resistance they present to flow, while for free-flowing powders AE can approach zero as the powders fluidise. The five materials tested exhibited a relatively broad range of AE values, but a robust relationship between AE and volumetric feed rate holds for all materials.

Figure 1 shows the measured feed rates for the five powders along with the predicted values. The predicted values accurately reflect observed performance in the GLD feeder. To challenge the predictive ability of this approach, two additional powders were tested - cement and lactose.

NETWORK & COMMUNICATIONS HARTING’S “SMART” HAN-MODULAR® ID CONNECTOR MODULE ENABLES INDUSTRY 4.0 HARTING is expanding its range of so-called “smart” connectors which can provide identification of key machine components or functional control elements and are also increasingly being deployed for machinery predictive maintenance. Communication can be performed using inexpensive bidirectional systems like the I 2 C bus, as well as standardised bus systems such as CAN Bus. Following on from the already established I 2 C ID module, the new CAN ID module is the latest product in the smart Han® series. Implementation as a Han-Modular® module ensures that identification is flexibly integrated into interfaces which comprehensively supply machines with power, data and signals, in the most optimum space-saving manner possible. The progress made by transferring identification functionality to the connector can best be illustrated by showing how such embedded intelligence features can be beneficial to the increasing trends for both modular designed processing machinery and machinery with multiple isochronous drives.

Case 1: ID module in modular designed processing machinery with exchangeable elements (Fig.1)

Figure 2 shows the measured feed rates for each of the original five powders, and the two new materials (shown in red), along with the predicted values. The same experiment was undertaken with the GZD feeder and Figure 3 shows the measured feed rates for all seven powders. Once again, the predicted values accurately describe the performance in the GZD feeder. This study demonstrates the feasibility of developing robust correlations between measurable powder properties and the volumetric feed rate delivered by different designs of screw feeder. In both cases it is dynamic powder properties which were found to be most relevant.

The Han-Modular ID module offers the double functionality of an identification tool and data storage device and paves the way for the customisation of the machine unit. In addition to local machine control, industrial Wi-Fi modules provide easy connection with the Industry 4.0 manufacturing environment.

Case 2: ID module in pluggable isochronous drives (Fig.2)

PREDICTING PERFORMANCE Multi-faceted powder characterisation provides an essential foundation for identifying properties that are most relevant to performance in any specific unit operation. Powder testers that enable this approach can therefore be extremely valuable for optimising a range of powder processes. MARCH / APRIL 2017 - PROCESS INDUSTRY INFORMER

Both conventional machinery and special-purpose machinery contain machine components characterised by movement processes made up of individual synchronously executing movements. The CAN bus, which operates in real time and is organised according to the “publisher-subscriber” principle, is ideally suited for the synchronisation of subscribers. The CAN ID module also enables the current configuration of the drives to be tested and the parameters that are determined to be transmitted to all other drives and the controller The machine may only start up if the drive is correctly configured. Start-up is blocked if any state exists other than the one desired. As a result, the CAN ID module offers advantages for both types of machinery. For Industry 4.0 applications, integration takes place via network-enabled devices or, in future, directly via an Ethernet interface. This in turn implements end-to- end networking of the data.

TACKLING MAINTENANCE COST ...THROUGH EFFECTIVE ASSET MANAGEMENT By Peter Jackson. BSc (Hons)Mech Eng. MIAM, Senior Consultant, MCP Consulting Group

L

eading manufacturing and service companies know that the effective Asset Management is a basic need for long term competitiveness. But even today, MCP has evidence that fewer than 10% of company sites in the UK have mastered this skill and hence the ability to claim to have ‘leadingthe-world’ status’. The overall UK profile of where sites are on the journey to becoming ‘world-class’ is shown in figure 1.

and techniques must be applied to mitigate the likelihood of its failure. The resulting annual maintenance schedules for each asset must be stored in the CMMS for reference in the maintenance planning process

3. PLANNING WORK. Weekly maintenance schedules are essential and should not interfere with output. A maintenance planner is mandatory, with tasks managed as Works Orders and results recorded. Maintenance best practice is to plan in advance more than 80% of the available resource man-hours

4. SPARE PARTS MANAGEMENT.

So, where is your company in terms effective asset management? You should consider the following 10 point asset management challenge… 1. Are you following a long term plan to apply asset management’s best practice ways of working? 2. Are you confident that each item of equipment (physical asset) has an appropriate, risk based annual maintenance plan? 3. Are you using a planning process such that technician or craftsman’s time is mostly planned one week in advance? 4. Are you sure you have the ‘right’ spares in stock? 5. Do you know that the total cost of your maintenance is correct for the current approach to asset management? 6. Is it clear that operations and project leaders care about the processes for effective asset management? 7. Do operational roles include asset management duties, tasks and objectives? 8. Do you apply specific asset management KPIs that are compared to targets and are actively used to drive continuous improvement? 9. Are there partnering arrangements with key outsourced providers or suppliers that allow for sharing risk and rewards? 10. Are you confident that the full scope of effective asset management is understood by all employees? If your response is NO to even a few of these challenges, then an effective asset management programme will deliver benefits to your organisation. Below we address the 10 challenges above for a sustainable asset management (AM) journey

Spare parts account for approximately a third of annual maintenance spends. The subject is gaining greater attention under the title Maintenance, Repairs and Operating Materials (MROM) management. From developments of techniques in Supply Chain Management (SCM) their application for engineering spares management is entirely appropriate. Traditional storemen are being encouraged to be ‘Subject Matter Experts’ (SMEs) in the complex world of MROM management.

5. COST OF MAINTENANCE. Guidelines suggest what should be the annual cost of maintenance relative to the replacement-as-new value of all the assets in a given portfolio. Depending on the business sector, world-class providers are expecting the maintenance budget to be between 1 and 3% for a highly developed AM system. Are you meeting this target?

2. MAINTENANCE PLANS After determining how important an asset is the appropriate tools

38

Measuring the management of workload and the effectiveness of the planning to ensure costs are in-line with budgets, and the equipment is performing at the design standards is a must. Visually showing the results as trends in a dash board format is current best practice.

9. OUTSOURCING. Is appropriate where there is a business benefit…but think before leaping into the arms of a provider hoping they understand the subject which is a mystery to you. If you cannot write a comprehensive user requirements specification (URS) for the outsourced subject you need to become knowledgeable before you outsource.

10. UNDERSTANDING AND COMMUNICATION. Regular communication of the progress and results of the full application of AM across the business is necessary to ensure a culture where application of world-class processes become ‘business as usual’. There are many examples of how such an asset management programme has achieved success, for example:

A LARGE SERVICE ORGANISATION An organisation’s asset base has grown by 80% in the past 4 years but with only a 20% growth in asset management costs. A multimillion cost avoidance through applying best practice ways of working following extensive re-training.

6. FUNCTIONAL INVOLVEMENTS.

A DRINKS MANUFACTURING SITE

AM cannot be delivered as an engineering initiative alone. Managers, project engineers, HR and finance all need to recognise their involvement in the delivery of an effective AM system.

Site productivity has increased from a starting position of 55% to 70% today over a 4 year journey. This was achieved through applying best practice asset care.

7. OPERATOR ASSET CARE (OAC).

A FOOD PRODUCER SITE Following a programme of training and then sustaining new practices the site has been recognised as the site of choice in the group and developing from an AMIS score of 54% in 2012 to 72% in 2016.

A DIVISION OF A MAJOR PHARMA COMPANY

1. LONG TERM STRATEGIC PLAN Improving AM has to be done in a formal strategic manner. ISO 55000 clearly indicates the need for an AM system that describes the policy and strategy for life long care of installed assets. The AM Policy and Strategy documents need to be ‘owned’ by those involved

8. KPIS.

For highly reliable equipment performance it is essential that those who operate (use) the equipment do so it a sensitive manner. OAC engages the user in the correct use of equipment and to do whatever maintenance they can do for themselves.

Over a 5 year period the division (18 sites in 14 countries) was guided and supported by MCP to introduce better working practices. The development of confidence at each site is always difficult to express, but highly valued by all involved. Some practical results included: • Identifying 5 % more assets than were not previously recorded. • A total across the division of 40% fewer breakdowns • Overtime reduced by 45% • Late PMs…a thing of the past • A total AM cost reduction approaching 20% lower costs
