HOW TO MANAGE VAPORISATION IN AN ANALYTICAL SYSTEM Doug Nordstrom and Tony Waters, Swagelok Company
AVOIDING FRACTIONATION FOR ACCURATE SAMPLING
4 WHAT'S NEW IN PROCESS TECHNOLOGY - NOVEMBER 2012
If the analyser in your analytical system requires gas but your sample is liquid, the only option is to convert the liquid to gas. This process is called vaporisation or flash vaporisation. The objective is to convert a sample of all liquid to all vapour instantly - without changing the composition.
t is not easy to vaporise a sample, nor is it always possible, so make sure it’s really necessary and possible before you try. You should always analyse a liquid in a liquid phase unless there are strong reasons for analysing in a vapour phase. If you proceed with vaporisation, it’s important to understand the difference between evaporation and vaporisation. Evaporation occurs gradually with an increase in temperature. Vaporisation occurs instantly with a drop in pressure. It’s not possible to vaporise a sample by increasing temperature. Heat causes evaporation and adding more heat simply makes evaporation happen faster. In a mixed sample, evaporation will allow some compounds to evaporate before others, resulting in fractionation. Vaporisation, done properly, ensures that all of the compounds vaporise at the same time, preserving the sample’s composition. However, it is possible for things to go wrong when vaporising. Instead of flashing the whole sample into a vapour, you could unintentionally cause a combination of vaporisation and evaporation, resulting in fractionation. Once a sample of mixed compounds fractionates, it is no longer suitable for analysis. With fractionation, a common scenario is for lighter molecules to evaporate first and travel on towards the analyser, while the heavier molecules remain behind in the liquid phase. Even if at some later point in the process a fractionated sample appears to be all gas, the mixture will not be of the same molecular proportions as it was before fractionation. It will no longer accurately represent the product taken from the process line. Let’s take a closer look at the process of vaporisation and how we can manipulate the variables - temperature, pressure and flow - to ensure proper vaporisation and an accurate analytical result.
Understanding vaporisation To vaporise a sample, one typically uses a vaporising regulator, also called a vaporiser, which is a pressure-reducing regulator with the capacity to transfer heat to the sample at just the right location.
Vaporisation consists of a three-stage process (see Figure 1). First, the sample enters the vaporiser as a liquid. At this point, the liquid should not be bubbling or boiling. Second, the liquid passes through the regulating orifice in the vaporiser, resulting in a severe and sudden pressure drop, which vaporises the liquid. At the same time, heat is applied, which enables the vaporised liquid to remain a vapour. Third, the sample, now a gas, exits the vaporiser and travels to the analyser to be read. Due to the immediate transition to the vapour phase, the composition of the gas is unchanged from that of the liquid, ensuring an accurate reading. In this delicate process, there are many variables or inputs that determine success or failure. For the purpose of this discussion, let’s say there are two main sets of inputs. The first set of inputs concerns the composition of the sample. Depending on the composition of the sample, it will begin to bubble and finish vaporising at different pressures and temperatures. We’ll need to know what these pressures and temperatures are to successfully manage the process. The second set of inputs concerns settings that you control in your sampling system: pressure, temperature and flow. Pressure and temperature are controlled at the vaporiser, while flow is controlled downstream at a rotameter (variable area flowmeter) and needle valve. We set these inputs based on what we know about the first set of inputs. Proper vaporisation requires a delicate balance of all inputs. Even when approaching vaporisation in a systematic manner like this, the process does require some trial and error, so we’ll also talk about how to diagnose and address problems.
Understanding your sample The best way to understand the first set of inputs is with a phase diagram. A phase diagram plots pressure and temperature, showing at any pair of conditions whether a substance will be vapour, liquid or solid. The lines indicate the interfaces between two phases.

Gases & fluids
Figure 1: The three-stage vaporisation process.
Phase diagrams for most pure gases are available on the internet, for example, at http://encyclopedia.airliquide.com. But diagrams for gas mixtures are very difficult to create without commercial software. Figure 2 represents a phase diagram for 20% hexane in pentane. When the sample is above the bubble point (blue line), it’s all liquid. We want the sample to be all liquid when it enters the vaporiser. When the mixture is below the dew point (gold line), it’s all vapour. The sample must be all vapour when it leaves the vaporiser. Between the bubble point and dew point lines is what we call the no-go zone. This zone is the boiling range of the sample. Here, the mixture is in two phases, part liquid and part vapour. Once a sample falls into the no-go zone, it is fractionated and no longer suitable for analysis. The objective in vaporisation is to set the temperature, flow and pressure so that the sample skips instantly from the liquid side of the no-go zone to the vapour side of the no-go zone. With pure and nearly pure samples, there is little to no boiling range or no-go zone. The bubble point and dew point lines are on top of each other or nearly so. Indeed, pure and nearly pure samples will convert to vapour of the same composition, whether through evaporation or vaporisation. Some industrial samples approach this level of purity and convert easily. On the other hand, some samples have such a wide boiling range or no-go zone that they cannot be successfully vaporised. There is no way to skip from the liquid side of the no-go zone to the vapour side of the no-go zone. We are unable to manipulate the

variables - temperature, flow, and pressure - in such a way as to avoid fractionation. Most samples fall between these two extremes. For example, in Figure 2, the band between bubble point and dew point is narrow enough that with the proper settings we can enable the sample to effectively skip from the liquid side of the no-go zone to the vapour side. At the same time, the band in Figure 2 is wide enough that we cannot afford to be careless. Indeed, we will need to be skilful in our manipulation of the variables or we will end up with a sample in the no-go zone.
Setting temperature, pressure and flow Let’s continue to work with the sample in Figure 2 (20% hexane in pentane) and see how we can set our inputs to ensure successful vaporisation. In general, at the inlet, we want high pressure and low temperature. At the outlet, we want high temperature and low pressure. But there are limits as to how high and low these parameters can be, and not all of them are under our control completely. Vaporisation is basically a balancing act between the variables. Here is a four-step process for setting your inputs:
Step 1: Determine the inlet pressure at your vaporiser This pressure, which is fixed, is your process pressure, provided your vaporiser is located close to your sample tap. In Figure 2, that pressure is 4 bar. Higher pressure is better because it allows you to keep the vaporiser temperature higher without boiling the incoming liquid.
6 WHAT'S NEW IN PROCESS TECHNOLOGY - NOVEMBER 2012
Step 2: Set your inlet temperature, or the temperature of your vaporiser There are two objectives. First, the temperature must be low enough that when the sample enters the vaporiser it is entirely a liquid and isn’t bubbling. In Figure 2, the bubble point at 4 bar is 88°C, but we want to build in a cushion, so let’s choose 80°C, a round number far enough away from 88°C to be safe. The temperature must be high enough to contribute to the complete flashing of the sample, because when you vaporise the sample, the temperature drops, in accordance with the laws of energy conservation. The sample temperature must be high enough at the outset so that after the pressure drop the sample is not in the boiling range or no-go zone. In Figure 2, the vapour temperature after the pressure drop is 60°C, just on the vapour side of the dew point line.
Step 3: Set the outlet pressure at the vaporiser Your objective is to drop the pressure below the gold dew point line. In Figure 2, the outlet pressure is set to 1.5 bar. If the outlet pressure were any higher in this example, the sample would fractionate.
Step 4: Set your flow Flow is set downstream at a valve and rotameter, not at the vaporiser. In a sampling system, high vapour flow is desirable because it moves the sample to the analyser faster. However, high flow can be problematic too, because high flow results in a greater drop in temperature at the time of vaporisation. In Figure 2, the purple line illustrates the temperature drop. As

flow increases, the purple line angles more sharply to the left.
Watching out for time delay While fractionation is one problem in vaporising samples, another is time delay. Time delay - the amount of time it takes for a sample to travel from the process line to the analyser - is always a challenge when employing a vaporiser. The industry standard for time delay is one minute, but it can take many times longer if you’re not careful with your vaporiser set-up. Time delay can be an issue on both the liquid and vapour side of the vaporiser. On the liquid side, the difficulty is caused by the sample’s degree of expansion when it is vaporised. A small amount of liquid creates a large amount of vapour. For example, the volume of methane increases about 600 times when it flashes from a liquid to a vapour. Hydrocarbons expand about 300 times. With such a dramatic difference between the liquid and vapour volume, it’s easy for liquid on the upstream side of the vaporiser to be sitting around for a while before it is vaporised. For example, with a vapour flow of 600 mL/min, the liquid flow may be less than 2 mL/min. If your vaporiser is located near the tap, the best solution to this problem is to install a bypass on the liquid side of the vaporiser, so the sample being vaporised is always fresh. In addition, try to minimise the volume of the probe and tubing preceding
the vaporiser. Less volume results in a faster response. To address time delay on the vapour side of the vaporiser, you may be tempted to increase flow, but as explained above, high flow in combination with insufficient heat at the vaporiser could result in fractionation, with liquid passing through the vaporiser to the downstream side. A better way to reduce time delay on the vapour side is to minimise volume. For example, move the vaporiser closer to the analyser or build a fast loop on the liquid side.
Heat transfer in the vaporiser Another variable influencing the temperature drop is the heat transfer capability of the vaporiser. Some vaporisers are constructed in such a way that heat transfers more efficiently to the sample. When the liquid sample converts to a vapour and its temperature drops, it draws heat from the stainless steel surrounding it. The critical question is: how efficiently can the vaporiser replace that heat and keep it flowing to the sample? The more heat the sample can draw, the less its temperature drops during vaporisation. In some instances, it is possible for the vaporiser to be hot to the touch on the outside but cold at the core inside. That’s because the vaporised sample is drawing lots of heat and the vaporiser cannot transfer enough heat to keep up. The best solution is to reduce the flow.
In sum, the angle of the purple line in Figure 2 is a product of the flow rate and the heat transfer capability of the vaporiser. With a good vaporiser and low flow, the line will become more vertical. Unfortunately, there is no easy way to calculate the location of the purple line, and it is not generated by any known software program. As a result, vaporisation involves some approximation. As a rule of thumb, keep the flow rate as low as possible without causing an unacceptable delay in the sample’s travel time to the analyser. It’s better to start with a low flow rate and experiment with increasing it than to start with a higher flow rate.
Troubleshooting Phase diagrams will enable you to approximate temperature, pressure and flow settings, but some troubleshooting will still be required. One sure indication of a problem is poor repeatability in analyser results. There are two possibilities when the sample is fractionating instead of vaporising, with Problem 1 being the more common:
Problem 1: Only part of the sample is being vaporised Liquid is passing through the vaporiser and sitting in the tubing on the downstream side. Eventually, it evaporates. When it does, it draws heat from the surrounding tubing, making the tubing cold to the touch or causing frost or ice to form.
NOVEMBER 2012 - WHAT'S NEW IN PROCESS TECHNOLOGY 7
Gases & fluids
• Signs of the problem: Vaporiser outlet and downstream tubing is cold to the touch or has frost or ice on it. (Note that in many cases, liquid on the downstream side of the vaporiser may pass beyond the area of the vaporiser and into other components, such as flowmeters and filters, where it can cause considerable damage.) • Solution: In the approach above, your best option would be to reduce the flow rate. Another option would be to lower the vaporiser outlet pressure, if that is possible. A third option would be to increase the heat to the vaporiser, but in this case you risk causing Problem 2 (see below).
Problem 2: The sample is boiling at the inlet to the vaporiser It is fractionating before it can be vaporised. Lighter molecules evaporate and create a ‘vapour wall’, which pushes the liquid back into the process. A portion of that vapour wall then cools and condenses. Finally, the liquid sample moves again towards the vaporiser, where the lighter molecules evaporate, starting the cycle all over again. Meanwhile,
the heavier molecules move on towards the analyser for an inaccurate reading. • Signs of the problem: The inlet tube to the vaporiser twitches, sometimes violently, and the measurement values oscillate. • Solution: Lower the vaporiser temperature.
Conclusion Vaporising a liquid sample is challenging. In many sampling systems around the world, vaporisers are fractionating samples and sending unrepresentative samples to the analyser every minute of every day. You can dramatically increase your chances of success by researching a phase diagram of your system’s particular mixture of compounds. You can further increase your chances of success by understanding what is occurring in the process - specifically, by knowing what the variables are (temperature, pressure and flow) and their role in influencing the process outcome. With this framework in place, you can come very close to the right settings, making adjustments in accordance with the signs and symptoms you observe.

TRANSPORTABLE HYDROCARBON DEWPOINT ANALYSER Michell Instruments has developed a transportable version of its hydrocarbon dewpoint analyser. The key function of this version will be to enable engineers to provide a fast response for investigations into the quality of natural gas, wherever it is needed. The Transportable Condumax II measures hydrocarbon and water dewpoint (key indicators of the quality of natural gas) in the same way and to the same accuracy as the online version. The analyser is fitted into a robust transport case with rudimentary sampling system suitable for performing supervised measurement sequences. A typical application for the Transportable Condumax II would be investigations into the performance of hydrocarbon reduction processing by natural gas producers. The analyser can be brought into operation quickly at any point in the process to help resolve issues. Gas pipeline transmission operators usually have online hydrocarbon dewpoint analysers installed at the entry and delivery points of their pipeline network; however, the Transportable Condumax II allows for checks of quality to be made at any point within the pipeline. Electricity-generating companies that operate gas turbines need to be sure of the superheat margin between the dewpoint and delivery temperature of the fuel gas to avoid damage caused by liquid condensate in the gas, as well as avoiding environmental levies on emissions.

Virtual plant planning, retrofitting and maintenance
Process plants have useful lives of 30 to 50 years, during which time they are routinely retrofitted. Virtual reality software simplifies and helps keep track of retrofit planning and testing. Fraunhofer researchers and BASF SE are jointly developing VR solutions for the plant life cycle. With over 110,000 employees, BASF is the world’s largest chemical company. At its headquarters in Ludwigshafen, the company runs over 160 production facilities, two steam crackers, two gas and steam turbine power plants and one sewage treatment plant. Virtual technologies are helping make information and data on every plant on the premises available digitally to planning engineers, process engineers, assembly coordinators, safety experts and asset managers. A virtual copy of a plant displays every possible view, whether in graphics or figures, in drawings or simulations. This expedites and improves the planning and implementation of new plants or additions and retrofits. Design reviews are an integral part of the planning process - a virtual model for design reviews realistically reproduces every component with the information related to it. The spatial representation makes hidden components or components aligned behind one another easily viewable. “We reviewed the design of a process plant retrofit together with BASF experts,” reports Sabine Szyler, virtual reality specialist at the Fraunhofer Institute for Factory Operation and Automation IFF. “The space in the plant can be determined far more easily. What sounds so obvious is really a giant leap in perception.”

The design was reviewed in the Elbe Dom of the Fraunhofer IFF’s Virtual Development and Training Centre VDTC in Magdeburg. “After all, the 6 m high, 360° projection surface projects a level of a plant which is virtually identical to the original. This gives viewers the sensation of standing directly in the plant,” explains the researcher. The three-dimensional data from BASF’s planning tools, including the metadata of the plant’s individual components, were exported into the Fraunhofer IFFresearchers’ special virtual reality software - the Virtual Development and Training Platform. This enabled plant operators, plant planners and their colleagues, such as piping contractors, equipment and instrument engineers, steel building contractors or safety supervisors to view details of the plant faithfully reproduced at full scale in the virtual model and clarify many questions such as whether all of the operating elements are easily accessible or all the safety valves are easily operated during an inspection. “We are so impressed by the design review with virtual reality that we have set up two VR stations in Ludwigshafen. That enables our planning teams there to review designs of other plants any time,” says Axel Franke, Senior Engineering Manager at BASF. A retrofit plant performs differently than it did previously and, in the worst case, incorrect operation could bring all plant operation to a complete standstill. Continuous safety training is therefore a top priority in chemical plant engineering. A virtual interactive learning environment is already being used for training in Ludwigshafen. Fraunhofer experts designed a scenario for the retrofit of a nitric acid plant, which enabled the team of operators to inspect and get acquainted with the plant before its commissioning. The Fraunhofer experts set up a mobile VR training station directly in the control room. The training module presents the complete 3D model of the plant. All of the metadata such as serial numbers, temperatures, pressures and media as well as training materials can be viewed. Workers were able to familiarise themselves with its new operation, identify new access points and learn new safety regulations. The experts from BASF and the Fraunhofer IFF agree that plant engineers will be unable to operate internationally in the future without virtual technologies. BASF is working on intensifying its use of virtual technologies in the future in order to maintain its leadership among chemical plant operators. The Fraunhofer IFF will continue providing conceptual support. Fraunhofer-Gesellschaft www.fraunhofer.de
GIGABIT ETHERNET SWITCHES Hirschmann has added two unmanaged gigabit ethernet switches to the Spider family. The Spider II Giga EEC Pro, available with either five twisted pair ports or two additional SFP slots for fibre-optic transceivers, supports QoS compliant with IEEE 802.1d. This allows prioritisation of data packets and means that the switch can be used for Profinet applications. The Spider II Giga EEC Jumbo is also available in two different 5-port versions, with or without SFP slots. Because both versions can handle Jumbo Frames with up to 9014 bytes of user data, they are particularly suitable for video applications. All switch versions conform to relevant industry standards for shock and vibration resistance as well as electromagnetic compatibility (EMC) and are built to comply with cUL508 safety requirements. Further features include 12/24 V power supply, IP30 protection rating, fanless cooling and an extended temperature range of -40 to +70째C. The switches can be cascaded as often as required, permitting implementation of locally structured networks with short transmission paths to the terminating equipment. The twisted pair ports have RJ45 sockets and support autocrossing, autonegotiation and autopolarity. The fibre-optic transceivers can bridge distances of up to 0.5 km (multimode) or 120 km (singlemode) and support autonegotiation and full-duplex mode. The switches are designed for mounting on DIN rails, and LEDs on the front panel indicate the device and network status. Daanet Pty Ltd Contact info and more items like this at wf.net.au/R842

LEVERAGING VIRTUALISATION ACHIEVING HIGHER BUSINESS CONTINUITY WITHIN INDUSTRIAL FACILITIES
© iStockphoto.com/Oleksiy Mark
Jim Frider, Product Marketing Manager, Invensys Operations Management
Virtualisation offers the promise of lower IT costs and higher levels of business continuity for industrial companies. This article provides a basic introduction to virtualisation and how it can specifically benefit industrial companies. High availability and disaster recovery scenarios are presented along with expected system performance targets for system downtime after an event or system failure.
oday, many of the world’s top companies are using software virtualisation technology to deliver significant cost savings, improved efficiency, greater agility, enhanced system availability and improved disaster recovery capabilities. The typical industrial facility, including manufacturing plants, utilities and processing companies, has many important software applications that can be virtualised. Software like HMI applications, process data historians and manufacturing execution systems (MES) along with other analytical and reporting applications can all be virtualised.
What is virtualisation? In simple terms, virtualisation is the creation and employment of a ‘virtual’ (software emulated) version of an ‘actual’ version of something. Broadly speaking, virtualisation can apply to physical devices, operating systems, network resources, device drivers or any actual thing for which a virtual equivalent can be substituted. Virtualisation is a form of software abstraction, which allows users to manipulate the virtual versions of things in ways which would be impossible for their physical counterparts. It is this fundamental ability to manipulate the virtual versions of things that provides the power and flexibility to derive so many benefits from the use of virtualisation technology.
Hardware virtualisation Hardware virtualisation employs software technology, like that offered by Microsoft and VMware, to transform or ‘virtualise’ a computer to create a virtual computer that can run its own operating system and applications just like a physical computer. With virtualisation, several applications and their required operating systems can run safely at the same time on a single physical computer with each having access to the resources it needs when it needs them. Today, this is all possible with commercial off-the-shelf computer hardware and operating systems. At the heart of the virtualisation process is a software component called the ‘hypervisor’, a term first coined during the early IBM mainframe days. There are two general categories of hypervisor. Type 1 hypervisors run directly on the physical host hardware and manage ‘guests’ or virtual machines so their operating systems can run concurrently on the physical host hardware. This is achieved by intercepting instructions from the guest operating systems and resolving them so that the guests function properly in their virtualised environment. VMware ESXi and Microsoft Hyper-V are examples of type 1 hypervisors. Conversely, type 2 hypervisors run on top of the host operating system and are not as commonly used with PC-based systems.
system resources are contained within a VDI and accessed from a network server. As none of the software runs on the user’s local machine, less costly computer equipment can be used. IT support responsibilities are reduced and the burden of data backup can be removed from the user. Besides the many IT-related benefits, VDI users have the added benefit of being able to access their virtualised desktop from a variety of other devices including their smartphone, tablet or home computer.
Virtualisation platforms Many companies are now using virtualisation at the enterprise level to create entire virtualised computing infrastructures that allow IT departments to automatically deploy computing resources when and where they need them, with a minimum of manual IT intervention. Cloud-based implementations promise even more flexibility and economy by outsourcing computing resources to other vendors such as Microsoft with its Azure platform or Amazon and others. Virtualisation platforms are already providing businesses of all kinds with tremendous IT cost savings and improved infrastructure utilisation.
History of virtualisation The high cost of mainframe computers in the 1960s led IBM engineers to develop ways to improve the efficiency of their equipment. By logically partitioning their machines they were able to offer multitasking. For the first time multiple applications could run at the same time - significantly improving utilisation. As low-cost, PC-based client-server architectures became the computing standard in the 1980s and 1990s the focus shifted to exploiting this new architecture by delivering more computing resources and applications to more users. Virtualisation was not a technology considered by most IT departments. However, by the late 1990s the sheer number of servers and desktop machines reached the point where virtualisation technology became viable as a cost reduction strategy. In 1999, VMware released its first virtualisation products and by 2005 processors became available that directly supported virtualisation. Today, a majority of large corporations are using virtualisation to reduce their IT costs.
Phases of adoption Industrial companies often adopt virtualisation technology in two phases; we will call them Virtualisation 1.0 and Virtualisation 2.0.
Besides the virtualisation of industrial applications, another area of virtualisation that is gaining momentum is the virtual desktop interface (VDI). Commonly used desktop applications and their required
In this first phase the emphasis is on IT and how virtualisation can be used to lower IT costs, improve IT staff efficiency and improve hardware utilisation. IT works on creating virtual machines of key applications and consolidating them on corporate servers. This first phase of virtualisation allows companies to reduce their hardware

costs, improve their server utilisation and improve their ability to operate and maintain a wide range of software applications. IT service improves because IT takes on the responsibility for managing applications which have been reluctantly managed by the groups directly using the applications, like operations or maintenance. HMI applications, process data historians and web report servers are examples.
of applications since fewer applications reside on local servers. Fast deployments can be achieved as self-contained virtual machines can be easily deployed without having to install the required operating system, prerequisite software or the application itself on a dedicated server. Corporate standard libraries of virtualised applications allow the creation of standardised application configurations that deliver maximum value to the business. 3. Support: The implementation of virtual desktops allows much more efficient management of desktop machines, and since application software doesn’t reside on each desktop machine, new applications can be rolled out to a large number of users much faster. This also allows for more effective backup procedures, since all data stays on corporate or cloud servers, effectively eliminating data loss.
Virtualisation 2.0 During the second phase of virtualisation, companies often deploy multiple instances of the same application to ensure business continuity or to improve application performance via load balancing. For business continuity, multiple instances of an application, and the data servers furnishing it with data, are run simultaneously so that if the primary application or data server fails, the secondary application instance and data servers automatically take over and downtime is minimised. If simultaneous application instances are run on servers located in different physical locations, disaster recovery is much easier. Some applications can be run in load balancing mode when the processing load is shared across two or more virtual machines, improving the overall performance of the application without having to invest in a second physical server.
Benefits to IT, operations and engineering Virtualisation of industrial applications can benefit many groups within a business. Let’s explore the benefits gained from virtualisation based on business function, namely IT, operations and engineering.
IT benefits There are three main areas of benefit from virtualisation for the IT organisation: 1. Cost reduction: Through consolidation of physical servers, virtualisation allows much greater utilisation of server hardware so fewer servers are required and a reduction in the energy is consumed in data centres. Virtualisation also extends the life cycle of applications because they are insulated from hardware or software technology shifts, generating more ROI for the business. 2. Management: Fewer hardware upgrades are required over time, reducing capital expenditure requirements and IT workload, and the use of virtual machines facilitates centralised management
28 WHAT'S NEW IN PROCESS TECHNOLOGY - NOVEMBER 2012
Operations benefits For operations, business continuity can be achieved because multiple instances of the same virtual machine can run in an automatic failover mode. If the failover instance is located in a separate physical location, disaster recovery is also enhanced. The reduction in physical server footprint leading to a higher return on capital and a reduction in the mean time to recover (MTTR), lowering operational cost, and thin client PCs on the plant floor running virtual desktops reduce the support burden.
Engineering benefits For engineering, development costs are reduced since fewer physical servers are required with fewer modifications needing to be made over time to keep applications running properly. Virtualised instances of object-based applications, like WonderWare ArchestrA System Platform, can be developed and deployed faster than conventional applications; and since multiple instances of a virtual machine can run at the same time, developers can work in a more collaborative and efficient manner.
Levels of availability When we speak about a ‘high availability’ solution we typically mean a solution with redundant software and/or hardware components that ‘fail over’ to an unaffected system to enable a predefined level of availability over a specific time frame. Levels of availability are detailed in Table 1.

High availability combined with disaster recovery
The goal of a high availability and disaster recovery (HADR) solution is to provide a mechanism to automatically shift data processing and retrieval for a critical industrial application to a standby system; for â€˜normalâ€™ failure scenarios to a standby system in the same facility or, in the event of catastrophic events, to a standby system located in a different geographic location. By combining HADR architectures, industrial applications can be made highly available and able to quickly recover from a disaster.
It is possible to achieve Level 2 or even Level 3 availability for applications like HMI and supervisory control using two, preferably identical, hardware servers (bought at the same time) each loaded with an identical virtual machine. Identical hardware and virtualised applications help ensure that if a failover occurs there are no deviations in system performance resulting from differences in hardware or software. To achieve Level 4 availability usually requires an investment in fault tolerant hardware, including servers, disk systems, power supplies and network cards. At this availability level, downtime is reduced to very low levels; less than 5 minutes per year, for example. The performance of any high availability (HA) solution is dependent on the quality and implementation of the HA architecture.
Disaster recovery implementations With the risk of natural disasters and a growing threat from terrorism, many industrial companies are exploring ways to recover faster from possible catastrophic disasters. Virtualisation provides a realistic and practical way to recover critical applications and their associated data more quickly and economically. Like high-availability implementations, if identical physical servers and identical virtual machines are run together in failover mode, but located in different geographic locations, a Level 2 or Level 3 availability can be achieved.
Summary Todayâ€™s virtualisation software solutions from Microsoft, VMware and other vendors provide a cost-effective way to improve the availability and disaster recovery capabilities of critical, industrial applications such as HMI and supervisory systems. Standard, off-the-shelf computer hardware and software can be used to lower costs and reduce the level of expertise needed to implement these types of solutions. Any manufacturer, processor or utility needs to evaluate these new approaches so that they too can mitigate risks and ensure continuity at their facilities.

CRYOGENIC VORTEX MASS FLOWMETER Sierra Instruments has introduced a cryogenic version of its InnovaMass 240 multivariable mass vortex flowmeter for advanced, more reliable measurement of liquefied gases, including liquid nitrogen, liquid oxygen, liquefied natural gas (LNG) and liquefied petroleum gas (LPG), at temperatures down to -200°C. Historically gauged by inexact turbine flowmeters, liquid gas flow can now be calculated with greater precision, since the InnovaMass contains no moving parts that will wear out or require service - an advantage that provides stable readings and an increased service life. The cryogenic version has undergone extensive testing and field validation over the last several years, proving that the meter is preferred versus traditional turbine meters for measuring mass flow rates of cryogenic fluids down to -200°C. Using a special cryogenic temperature RTD, mass calculations are done with the latest density equations of state for liquid oxygen, nitrogen, argon and carbon dioxide, and it can provide direct readings of mass flow rate, volumetric flow rate, temperature and density. Smart electronics extends the range down to a Reynolds number of 5000. The flowmeter can be loop powered with power in, a programmable analog output and a HART or Modbus signal riding on the same two wires. Field-configurable ranges, alarms, outputs and displays can be configured via six push-buttons or via a magnet through an explosion-proof window.

LARGE-CHARACTER PRINTER/LABELLER The Linx IJ355 and IJ375 high-definition case coders are two new large-character printers from coding and marking specialist Linx Printing Technologies. Claimed to be able to cut production costs while maximising line uptime and print quality, the printers provide a cost-effective, easy-to-use alternative to other largecharacter printers, and to the labelling or pre-printing of secondary packaging. The printers use ReFresh ink recirculation system, have a robust design and printhead protection technology which result in reduced downtime and savings on consumables. The ink recirculation system’s technology provides good print quality and also avoids wasted ink during printhead cleaning, thus saving time and money ordinarily wasted on purging procedures. Ink and dust that collect on the nozzles is removed with an air knife, an ink purge takes place, then ink from this procedure is collected, passed through a high-performance filter to remove impurities from the system and recirculated. Operators only need to perform quick, simple maintenance on a regular basis in order to keep the printer in optimum operating condition. The tough stainless steel nozzle guard protects the printhead from possible damage, caused by impact with the boxes on the line, while remaining close enough to the packaging to ensure print quality is maintained. The robust stainless steel lower casing and printhead protection mean the Linx IJ355 and IJ375 are robust enough to cope with the most demanding production lines, delivering savings on consumables and minimising downtime. The printers come with a full-colour LCD interface and touch-screen operator controls, with print preview and icon-based message selection. The control unit is detachable for handheld use or for mounting in a more convenient location. A set of robust accessories is also available from Linx to provide simple and accurate mounting of the printer onto the production line.

COMPACT PRESSURE SENSORS Suitable for pneumatic applications in robotics and handling, ifm efector’s PQ compact pressure sensor series is now equipped with NPN circuit. Using a sealed measuring cell, these sensors detect the pressure in the vacuum and overpressure range. The piezoresistive silicon cell measures, depending on the selected unit, between -1 and 10 bar or -1 and 1 bar. Due to the special sealing of the measuring cell, the pressure sensors are insensitive to liquids such as condensed water and deposits that might occur in the system. The sensors have good overload resistance and an accuracy of less than ±0.5%. The sensor’s slanted 4-digit display can be electronically rotated by 180° and read at a distance, from the front or from above. The display colour is selectable, with a green display colour for the acceptable range and red when the switching point is exceeded or not reached. Two programmable switching outputs or one switching output and one diagnostic output provide flexible use. The sensors are easy to install by means of integrated mounting holes

Reliable stormwater measurement In the course of modernisation of one of its stormwater basins, the wastewater treatment plant Waiblingen-Hegnach decided to implement radar measurement technology from VEGA. The basin, which is 5 kilometres away from the treatment plant, is monitored reliably by three radar sensors. The employees of the sewage treatment plant at Waiblingen-Hegnach, Germany, certainly cannot be accused of not being close to nature. Yet they do have mixed feelings about spider webs! Spun beneath the ultrasonic sensors, spider webs used to cause measurement uncertainties again and again. But animals and insects were not the only culprits: foam and even sunlight also had adverse effects on
The shaft of the sewage pumping station is located in the middle of a floodendangered area, so the radar gauges were designed with an IP68 protection rating.
the ultrasonic measurement. Indeed, the Waiblingen staff has really had enough of foam. Once, the wastewater discharge from a nearby shampoo manufacturer caused major problems for the ultrasonic measurement due to the huge amounts of foam generated. While planning the new instrumentation for the stormwater basin, plant manager Frank Sura knew exactly what he wanted. “As a matter of principle we use non-contact methods for wastewater wherever possible. Because of the oil, dirt and debris in the water, ultrasonic technology was often deployed, accompanied of course by the very well-known difficulties of using that method.” That is why, in the course of modernisation of the stormwater basin, Vegapuls WL 61 radar level sensors were used instead, at three different measuring points. Since May 2011, the instruments from VEGA have been delivering reliable and stable readings. “It is certainly not a particularly difficult application, but it has to function reliably,” explains Sura. “Beside their reliability, what really convinced us about radar instruments was their price, which was hardly different from that of ultrasonic devices.” All plant components are connected via a control system, so the team working at the sewage treatment plant has access to all functions at all
times. This is important because such mid-size treatment plants tend to be minimally staffed and many different areas have to be monitored. A remote control system provides security, setting off an alarm in case of damage or contamination by toxins or other hazardous substances. The stormwater basin, one of a total of 13, is 5 km away from the treatment plant and situated directly on the banks of the river Rems. The measurement data is transmitted every half hour to the control system via a mobile phone network, and the radar sensors are deployed at three measuring points. All units have Ex certification, a necessary precaution since fuels or solvents can also be present in the wastewater. Location Number 1 is directly in the open stormwater basin. There, the sensor monitors the level in the basin and, if necessary, puts the discharge pumps into operation. In the nearby sewage pumping station, another radar sensor is installed in the pump shaft. Previously, this measurement was achieved via a pressure measurement. The entire facility is located in a flood-prone area - the Rems has a small channel, but a large drainage area, and as a result, the water level can rise substantially within a few hours. That’s why the measuring instruments have an IP68 protection category, which allows them to be immersed in floodwaters. The third instrument is located some distance away, hidden in the middle of a meadow. There, a vortex valve regulates discharge into the sewer line. Most of the water generally flows past the basin. Only when there is a heavy rain, for example, and the rainwater runoff increases to a multiple of the normal wastewater flow, do the stormwater basins come into play. They buffer the dirty water and take the load off the treatment plant. The tank contents stored during the heavy rain are forwarded to the sewage treatment plant little by little after the rain event. To ensure proper control of this process, the vortex valve has to work flawlessly. “Very few people have an idea of what can be found in sewage. We’ve already had to remove boulders, two-by-fours and flashlights. A large tree branch can block the vortex valve very quickly,” continues the plant manager. In the past, someone from his team always had to go and check if there was really a blockage or if it was just another industrious spider that had built its web under the ultrasonic transducer! This is no longer necessary, since a radar level gauge is keeping watch there now. Further upgrades, including additional stormwater basins within the catchment area of the wastewater treatment plant, are planned for the future.

LED OPEN FRAME MONITOR
The IDS-3110 is a 10.4″ SVGA industrial LED open frame monitor. The open front bezel design enables flexible and customised face plates for easy re-engineering and is suitable for any embedded application. The versatile mounting methods include rear and VESA mounting (75 x 75 mm or 100 x100 mm). The IDS-3110 comes in two versions: IDS-3110 standard and IDS-3110E. IDS-3110 standard provides 400 nits brightness and -20 to 60°C wide operating temperature with dual VGA and DVI signal interfaces. IDS-3110E is a more economic version which supports 230 nits brightness and 0 to 45°C operating temperature with VGA signal interface only. The IDS-3110 incorporates a simple 2-piece metal frame structure for a slim design 30 mm thick (non-touch solution) while most models are over 40 mm thick. This is a space saving of 20% and a weight reduction from 2 kg to 1 kg for non-touch solutions. Compared to traditional CCFL backlights, LED backlights allow for thinner panel designs and low power consumption. The IDS-3110 comes with an industrial-grade panel and LED backlight which saves 20-30% on power consumption and reaches higher brightness. The 400 nits brightness and 700:1 contrast ratio together brings much better visibility than common monitors, particularly in environments with strong ambient light. The wide viewing angle of 160° horizontal and 140° vertical provides a wider range viewing area for end users. In addition, IDS-3110’s wide range operating temperature of -20 to 60° C makes it suitable for harsh environments. Advantech Australia Pty Ltd Contact info and more items like this at wf.net.au/R068
DATA ACQUISITION SYSTEM The Dewetron DEWE2 data acquisition system allows for mutliple simultaneous sampling Trion plug-in modules, combining the modularity of PXI with a larger front panel capable of containing eight RJ45 connectors for strain gauge sensors, six or eight IEPE sensor connectors, or four or eight isolated high-voltage inputs on a single Trion module. The modules are inserted from the front of the DEWE2 chassis. Each module can be combined and exchanged directly by the user in seconds. They plug in and out using the same locking/ejector mechanism made popular by the PXI standard. This allows the adaptation of DEWE2 instruments for every sensor and every application quickly. The function of each measurement channel as well of the connected sensors can be proofed easily via a system check. This results in a reduction of user errors, which saves valuable time. Different chassis, most with a battery pack for independent power supply, are available. The series is ruggedised and provides a high channel density. Analog, digital, CANbus, GPS, counter and video signals are hardware synchronised already during the measurement, due to the built-in Sync-Clock technology. There are instruments offering from 4 to 18 Trion slots, with or without a built-in computer. The DEWE2-A4 is an all-in-one platform with four slots for any combination of Trion modules, and features an Intel i7 processor running Windows 7, and a built-in display and keyboard.

INTEGRATED PNEUMATIC ACTUATORS Norgren has launched a high-performance range of cylinders, designed to significantly reduce energy usage and operating costs for OEMs and end users in a range of processing applications. Conventional pneumatic control involves an arrangement of valves or valve islands, actuators, flow controls and sensors, along with connectors and accessories. In typical applications, up to 13 different components can be required for each actuator function. This complexity presents some intrinsic disadvantages and performance constraints. Norgren has developed IVAC (integrated valve and actuator control) - an integrated unit which combines the valve, flow controls, cushioning and sensors in a single actuator package. IVAC is a weight- and space-optimised actuator, suitable for a range of bore sizes from 40 to 80 mm, featuring an integrated valve and magnetically operated switches for complete actuator control. Able to be retrofitted or integrated within new systems, each unit requires only one pneumatic and one electrical connection, eliminating the need for multiple valve islands, components, tubing and accessories. A number of options and varieties are available including cleanline versions for industrial cylinders, industrial slave cylinders and easy washdown, helping OEMs comply more easily and cost effectively with hygiene regulations. The design of the integrated actuator is based on modularity to allow all components to be easily assembled and disassembled. The IVACâ€™s modular concept includes a special pilot module which is placed directly at the end of the actuator barrel, and the integration of a pneumatic interface, position sensing, display for status and electrical connection.

EXTEND YOUR CONTROL: DIGITISATION OF THE INDUSTRIAL WORLD
n today’s real-time and highly connected world, digitisation is radically changing day-to-day life. The digital world pervades our every waking moment and sometimes our sleeping moments too (check out the popular snoring app!). The world’s volume of digital data more than doubles every two years (Source: Discovery Institute’s Technology and Democracy Project, January 2008). By the end of 2012, 20 typical broadband households will generate more traffic than what flowed across the entire internet in 2008 (Source: AT&T). The majority of businesses (83%) believe they will be doing more than 50% of their services on the cloud. These statistics are indicative of the digital wave that has flooded our personal world and is now impacting our industrial world. The industrial automation space has traditionally been conservative, with a focus on reliability and high availability. Today, with these principles common across the digital world, many production plants, facilities and industrial businesses are expecting the same real-time, connected and mobile digital experience combined with the traditional principles of data resilience and availability in order to meet their production needs. Technology streamlining processes Complicated, multiple workflows of different roles in an industrial business can be managed in the digital domain but the seamless interoperability across the entire process control system enables the rapid identification of production losses and root cause, and immediate rectification of the fault - all minimising process downtime, the key contributor to profitability. These integrated solutions featuring enterprise-wide centralised control, mobile technologies and industrialised PCs at local control stations form the backbone of industrial digitisation. Put simply, with industrial digitisation, that which used to take hours (if not days) now takes minutes. The first critical piece of the industrial digitisation architecture is enterprise-wide centralised control. This can be achieved through the consolidation of disparate sitebased monitoring, control and operations intelligence solutions into one holistic production
management system that operates across all sites in the demand chain. Centralised control embeds standardisation in automation across the demand chain - emphasising the need for common visualisation and control standards. The second critical piece of industrial digitisation leverages the strength of mobility solutions, such as tablets and smartphones, which provide the flexibility necessary when consolidating operations for centralised control. The third key piece of industrial digitisation architecture is the use of localised, industrialised PCs (iPCs) in local stations. This is critical to centralised control and the strength of the industrial digitisation model. It is also important for production processes requiring high-maintenance activities (a physical presence) together with the need for digital visibility (SCADA). Building blocks for industrial digitisation Enterprise-wide centralised control combined with mobility solutions and local control station (iPC) architectures are the fundamental building blocks for industrial digitisation. With these in place, industrial businesses are leveraging the rapid paced digital world - effectively combining the real-time, connected and mobile, digital experience with traditional industrial automation principles of data resilience and high availability. Industrial companies that take up the industrial digitisation challenge drive more effective, agile and ultimately profitable businesses as their workflows are streamlined across their operations.
