AN ENGINEER’S VIEW

Money Engineering: 101

A

s engineers we spend most of our formative years expanding our technical and managerial experience, but rarely do we invest in cultivating the business acumen required to operate and run a profitable venture.

In lieu of this enterprise culture, we resort to the primal essence of a business, which for most of us means adopting a daily mantra of “job out - money in” the hustle of a small engineering company.

As many an entrepreneur would know, managing a small business is more than just balancing the books and accounting for expenses, it’s about charting a course, sailing a ship and keeping it afloat. It’s about cash flow.

But do engineers make for good business owners? While it is inherent in engineers to itemise, systemise and optimise, we would sooner bury our heads in advanced triple integration, than formulate a 3 month cash flow prediction. For the most part, we lack the insight for trade and commerce, and cannot comfortably adopt these concepts without intentionally endeavoring into the finance-discipline.

Without these basic business essentials, engineers are short a tool to effectively and profitably trade our intellectual property as a small business owner.

This, in turn, limits both the expansion of independent specialised engineering consultants within the engineering industry, as well as the individual life-span of these companies.

Ultimately, we require the empowerment of engineers, not so much with the principles of accounting, but rather with an economic–conducive ‘school of thought’. This would create appropriate flexibility in our thinking and assist us to incorporate relevant factors and dynamic variables into the functioning of a business. Paired with our natural ability for

problem solving, good business savvy would prove highly effective in establishing smart and operational business strategies.

As many an entrepreneur would know, managing a small business is more than just balancing the books and accounting for expenses

Substantial efforts have thus been made to ensure educated engineers are capable of designing and building fully functional ships, perhaps then the next step is to equip us to navigate the seas and sail.

COVER STORY

Specialised Demolition Furnaces in the steelmaking, glass, or general manufacturing industries have a finite lifetime before requiring significant maintenance and repair work. Jet Demolition offers a myriad of specialised services easily adapted to suit the challenging conditions of a furnace demolition project.

T

he company owns a variety of specialised machines and equipment modified specifically to work within the confined space of a furnace structure. “These machines offer us the best chance of improving on project schedules, resulting in decreased downtime for our clients,” says Kate Bester, Jet Demolition Contracts Manager.

Jet Demolition has modified various items of its equipment, significantly reducing the overall size, enabling them to fit and manoeuvre in incredibly confined spaces “More often than not, furnace shutdowns are planned over cold winter months, and will be on a 24-hour schedule so as to best minimise production downtime,” Kate explains.

THE SOUTH AFRICAN MECHANICAL ENGINEER

The elements that require demolition depend greatly on the extent of the maintenance or repair work to be undertaken. Smaller, less serious shutdowns often require only the burden and solidified product from within the furnace to be removed, so as to allow for localised repairs to the refractory and/or insulation lining. Other extensive repairs may call for the demolition and removal of the refractory lining, sections of the shell-plate, or even entire furnace structures so as to facilitate modernised installations.

Tight space are no problems

Jet Demolition has modified various items of its equipment, significantly reducing the overall size, enabling them to fit and manoeuvre in incredibly confined spaces. It has also recently lifted modified mini excavators onto engineered scaffolding, enabling it to demolish refractory lining at height.

“This activity has historically only ever been done by hand at this specific facility,” Kate reveals.

“We use specialised lances and tubes, affording us a better burn-rate through solidified iron, and have applied metallurgical research into develop-

VOL 69 June 2019

ing unique wire-packs suited specifically to the base-metals within the furnace to be demolished,” Kate continues.

Demanding working conditions

In addition, it is inevitable that furnace demolition activities have an array of extreme conditions and circumstances associated thereto. These range from working in a wet environment during quenching and cooling to working in an extremely hot environment with restricted visibility during lancing activities.

Specialised lances and tubes offer a better burn-rate through solidified iron “Just about every element of a furnace structure is large and heavy, and has the potential to cause harm. Thus it is imperative that there is no slip in focus or attention throughout all phases of the works,” Kate concludes.

Tech to Remove Harmful Gases New South African legislation decrees that by April 1 2020 existing plants must comply with Minimum Emission Standards (MES) in terms of meeting NO x (Nitrogen Oxides) levels of less than 350 mg/Nm 3. Some nitric acid plants are already compliant with the 2020 MES standards in terms of NO x. However, for other plants compliance with NO x emission requirements is border line, making it necessary to put new technology in place.

I

n chemistry, NOx is a generic term for the nitrogen oxides that are most relevant for air pollution. Nitrous oxide (N2O), commonly known as laughing gas, is produced as a by-product in the manufacture of nitric acid, an important raw material used among other things to make fertilizers. Nitrous oxide is a potent greenhouse gas implicated in the destruction of the ozone layer.

“Operators are under increasing pressure to produce more and more efficiently both from an operational cost and environmental point of view,” notes Neville Eve, General Manager of thyssenkrupp. “To meet the challenge of managing emissions to minimum levels and still be up on production requires proven technologies that allow cost-effective set-up and operation and at the same time make a significant contribution to environmental protection.”

The EnviNO x process is capable of removing NO x, and if required the greenhouse N 2O gas Turning gas into water

The EnviNOx process from thyssenkrupp is capable of removing NOx, and if required the greenhouse N2O gas, turning it into harmless nitrogen and water. The technology has been proven on an industrial scale with around 30 plants using the EnviNOx process around the globe, with two of these plants located in South Africa.

The EnviNOx reactor removes NOx through a process not dissimilar to what is used to reduce emissions in modern vehicles, namely selective catalytic reduction (SCR), which uses a catalyst and a small amount of ammonia in the reaction process.

ENVIRONMENT

Combating DISEASE Outbreaks The recent spilling of sewage into the Durban harbour has something in common with another recent event. Two hundred SANDF technical team members were called out to the Vaal Dam in November last year.

T

he water that thousands of people rely on is contaminated either by sewage or by pollution, putting people at risk of waterborne diseases.

We started asking ourselves: ‘Do we really have to build a field lab every time we go out to test water?’ That’s where the mobile lab idea was born”

In these situations, it is critical to test water and get the results quickly so the water can be made safe.

But these events usually happen far from big cities.

And that’s where the laboratories that can analyse water samples are. So driving back and forth means it takes much longer before people have safe water.

Mothers and water

“The idea for a mobile lab started a few years ago.

The moment that really sticks in my head happened during the Carolina diarrhea outbreak. The thenminister of water and sanitation said ‘I had to listen to moms crying about babies who were critically ill, asking: ’Why can’t we sort this out now?’’ And we knew we still had to go sample and drive three hours back to the laboratory, before we could even start the analysis,” says Prof TG Barnard, Director of the Water and Health Research Centre, University of Johannesburg (UJ).

“We knew if we had a laboratory on site, we could do things much faster. We could start testing water at a household level, telling people to bring their water and give immediate results,” Prof Barnard continues.

Building labs from scratch

In the past, the research team drove for hours to deep rural communities to test water and had to build a field lab from scratch.

“We started asking ourselves: ‘Do we really have to build a field lab every time we go out to test water?’ That’s where the mobile lab idea was born,” adds Dr Kousar Hoorzook. Research coordinator at the process energy environment technology station (PEETS) at the University of Johannesburg.

“For each trip, we packed up everything we needed

from the UJ laboratory, and carried it out of our building to a trailer outside. It would take nine hours to drive to the site. When we got there at 5pm, we would find we have a derelict hut to work in,” she says.

“Then we started cleaning the space. After that we would sterilise it. Only then could we start testing the water samples, and it would be 10pm already,” she adds.

Kousar is the co-designer of the lab with Prof Barnard and Robin Robertson, an industrial designer.

Off-the-grid

The laboratory design is really a ‘shell’ that can be customised, continues Prof Barnard.

Cholera Vibrio Cholerae human biopsy

The mobile lab runs its sample fridge and incubator, analysis equipment and air-conditioning on solar panels, a generator and batteries “The space inside was set up so we can bring in different types of equipment for various tests. We designed it with the idea of transporting as much equipment to test for as many viruses as possible.

The mobile lab runs its sample fridge and incubator, analysis equipment and air-conditioning on solar panels, a generator and batteries. It carries its own safe water supply and a side tent to accommodate more testing equipment and staff needing shelter.

Because it can operate without grid electricity or water, the mobile lab can stay on site for several days if needed,” he concludes.

INVESTMENT

Scaling up FLSmidth has relocated the manufacture of its core screen media products to the modernised Delmas Supercenter facility, providing a cost-effective base from which to grow its sub-Saharan markets.

“

The targeted efficiency improvements for the production lines at the facility will allow us to better serve our installed base of FLSmidth equipment in the sub-Saharan Africa and Middle East region,” says Stephan Kruger, FLSmidth Director for Manufacturing and Warehousing in the region.

This follows the 2017 decision by FLSmidth to proceed with an investment at the 120 000m2 premises in Delmas.

In-house manufacturing

In line with this strategy, FLSmidth has opted to focus on the in-house manufacture of three core product lines, polyurethane, wedge wire and ceramic wear solutions.

Fettling and cleaning before final quality checks are conducted on FLSmidth polyurethane screen panels

The company concluded the sale of its non-core screen media product lines, including woven wire screens, perforated plate and wire conveyor belts, to crusher support services. During this process, FLSmidth secured a preferential supply agreement to support local industry customers with the continued supply of these products.

Opted to focus on the in-house manufacture of three core product lines, polyurethane, wedge wire and ceramic wear solutions The transaction has also preserved 79 jobs in the manufacturing sector, retaining a considerable production capacity within the country. Thirty of the employees have been relocated to the FLSmidth Delmas operation.

Optimised production costs

“We have invested in state-of-the-art equipment, including full Computer Numerical Control (CNC) machining capability,” says Stephan. “The new facilities include 5-axis and 6-axis machining centres, introducing a high level of technology to support the product lines in our business while optimising production costs.”

The Delmas operation includes a 10 500m2 workshop with 120 ton lifting capacity and 11,5m under crane hook. More than 100 staff members are currently employed at the facility. It hosts modern offices, warehouse facilities and a dedicated training centre that can accommodate up to 65 people for technical training purposes.

TECHNOLOGY

Putting Digitalisation Into Practice There has been much conversation about the Industrial Internet of Things and Industry 4.0, but the focus has generally been about the concept and the technology surrounding this revolution, rather than about the ways it can be put into practice.

“

Recent improvements in connectivity, control and analytical capabilities have unlocked the potential for significant improvements in the cost, quality and productivity of industrial operations. However the secret to truly successful digitalisation for these companies lies in putting the technology to use in such a way that it delivers real and measurable customer value,” says Mattias Årstadius of SKF. The mistake that is often made is to focus on developing a system solution, rather than looking at the customer’s specific needs.

Digitalisation should be about improving customer performance. So, the first step needs to be to determine what value means to that specific company and what they consider to be their key performance indicators (KPIs).

The digitalisation of predictive maintenance

SKF has been working with a large pulp & paper company in Sweden to deliver one of their KPI’s, operational efficiency. With high levels of unplanned stoppages, condition monitoring was introduced.

Mattias Årstadius, SKF Industrial Sales Unit Manager Sweden

“Not only has this move to

predictive maintenance saved the paper mill several hundred thousands of euros in terms of downtime reduction, but the monitoring system is delivering real-time noise, temperature and vibration data to allow SKF to not only solve present issues but avoid future ones,” says Mattias.

Thanks to the introduction of 4G and 5G and real-time connectivity, the door is beginning to be opened to the next stage in predictive maintenance, the bigger picture.

Thanks to the introduction of 4G and 5G and real-time connectivity, the door is beginning to be opened to the next stage in predictive maintenance, the bigger picture Real-time data is also opening the door to far greater integration across the supply chain. For example, in the very near future, component manufacturers will be able to access customer machine data and will be able to manufacture replacement wearing parts before each asset actually needs replacing.

How digitalisation is transforming business models

Through condition monitoring and the digitalisation of the industrial process, traditional transactional models are increasingly being replaced by performance and functional based contracts.

“SKF is beginning to see this shift, with more companies choosing either its performance, or functional based contract models. The former is a base fee paid monthly, with a bonus performance payment added at longer intervals if the customer’s KPI’s have been reached. Functional model agreements however commit the provider to deliver in terms of functionality for an agreed fee. There are real advantages for both sides to these models and we believe we will continue to increase in popularity, as more companies begin to exploit the potential of digitalisation to create different ways of financing operational performance,” adds Mattias.

A case in point is a mining operation where SKF has placed 8 000 sensors on the production lines, monitoring 2 400 assets, such as pumps, fans, gearboxes and large rotating grinding mills. A continuous service agreement is in place with the mine owners and as a result of digitalisation, SKF has been able to document that the predictive maintenance measures being carried out are saving the company almost i8 million per year.

INFRASTRUCTURE

The Gift Of Water The port city of Pemba in the Cabo Delgado Province of Mozambique is receiving a gift of life with the area soon to extend its clean water supply following the installation of the 42 kilometre long bulk water pipeline which will provide water for the city’s growing population.

T

he new 500mm diameter ductile iron pipeline forms part of a larger project which includes new pump stations and the expansion of the well field to double the volume of water that can be supplied to Pemba. The pipeline is due to be completed and commissioned in August 2019 following 12 months of activity on site.

Tshwane based Nyeleti Consulting Engineers is part of an international project team entrusted by the Mozambican government’s Water Supply Investment and Assets Fund (FIPAG) to complete this project. Nyeleti’s services included the preliminary and detailed design of the 42km DN500 ductile iron transmission main. Some of the major tasks that have been completed include hydraulic and surge design of the new transmission main, route selection and an external condition assessment of the existing transmission main.

MAINTENANCE

Plugging Leaks Presently in South Africa, boiler tube leaks are something of a hot topic, as the country’s national power supplier continues to contend with various complex challenges, including that of boiler maintenance issues caused by, among other factors, boiler tube leaks.

T

his is not a uniquely South African issue, as the US-based organisation, the Electric Power Research Institute (EPRI), reports that power generation plants in the US and Europe have, on average, around 6% loss of plant availability due to boiler tube leaks, a major loss factor for these facilities.

Early leak detection

However, in South Africa, industrial solutions provider RTS Africa Technologies has an effective solution to the challenge of boiler tube leaks.

This is in the form of a boiler tube leak detection system from UK-based Procon Engineering.

“Early detection of boiler tube leaks include increased operating profit, personnel safety, availability and tube life,” says Ian Ian Fraser

Fraser, Managing Director of the RTS Africa Group.

“In addition, early tube leak detection means unscheduled outages can be avoided or at least reduced as can repair costs and secondary damage, with the attendant reduction in financial penalties and insurance costs,” he adds.

Picking up frequencies

Commenting on how the technology works, Ian says that Procon manufactures microphones which bear little resemblance to conventional audio microphones.

These microphones detect the very particular noise made by steam leaking from a boiler tube.

“The sound of a boiler tube leak has a particular frequency which these microphones are selectively able to detect. In itself, this is quite a technical feat, as the firebox of a boiler is a fairly noisy environment,” he explains.

The operational importance of the leak detection system is that it can detect small leaks before they become catastrophic failures.

A further key advantage lies in the number of microphones installed in a boiler. For example, a typical power station might have as many as 24 of these acoustic devices installed in a boiler. The output from the microphones is fed into an IT controlled display with each microphone being represented by a bar on the display. This shows the sound levels from each microphone inside the firebox. For recordkeeping purposes and system analysis, it is possible to print out the data from a Procon system.

When the leak occurs, the microphone nearest to the leak will display an elevated bar level. What is particularly useful is that other microphones in the area will also pick up the noise.

“The system has been designed not only to serve power stations, but also the range of boilers used in the broad spectrum of industry,” Ian explains. “With boilers which might service manufacturing or production environments, prevention of major failures will also assist in the avoidance of punitive financial penalties, and ultimately bring about a marked improvement in the company’s bottom line,” he concludes.

Sealing ventilation walls safely and easily Developed to assist coal mines to seal their ventilation walls and air-crossings, the Chryso Vent Block Sealer can seal any porous substrate quickly and cost-effectively.

Chryso responded to the coal mining industry’s need to address ventilation wall leakage, according to the company’s new business manager, Frans Bakselerowicz. The styrene acrylic copolymer sealer efficiently addresses the challenge of hollow blocks and joints in the walls.

“The conventional use of a bitumen emulsion paint-on application product had proved to be very labour-intensive and costly,” says Frans. “By contrast, the Chryso Vent Block Sealer is a spray-on product, using a knapsack pump which does not need any compressed air to spray. This allows its application even in back areas of a mine, where there are no electrical and compressed air services.”

The ventilation walls in a mine are usually made of concrete hollow blocks, clay bricks and corrugated iron sheets.

However, he emphasises that any porous substrate can be sealed, as well as gaps of up to 1mm in magnitude.

Any larger crack or hole can be repaired with a.b.e. paintable flashing tape and then sprayed over. In high leakage areas, a second coat can be applied if required.

An attractive cost saving Fast payback from steam turbine cogeneration systems makes this power source an attractive option across numerous industries. This is according to Leandro Magro, manager of steam turbines at Zest Weg Group who says that any factory with a boiler installed has a potential for cogeneration using a steam turbine.

that typically, industrial steam turbine models start from a 30kW capacity and go up to 150MW. “These turbines can operate at a very low steam pressure (5 bar or less) or a high steam pressure up to 140 bar, saturated or superheated steam up to 540°C,” he explains.

“Steam turbine cogeneration is not only

suitable for large installations but can play a vital role in medium and small applications, saving the end-user a significant amount in energy costs,” Leandro concludes.

Zest Weg Group , Tel: (011) 723-6000 Email:info@zestweg.com www.zestweg.com

“The electricity cost savings usually pay back the investment in less than three years, but this payback period can be further reduced depending on the applicable electricity price tariff in effect,” he says.

Power plants, sugar mills, pulp and paper mills, steel mills, petrochemicals, oil and gas installations, food and beverage manufacturing operations and many other industries including commercial and institutional facilities use steam turbines for electricity production or to drive mechanical equipment such as compressors, fans, mills and blowers.

When used for the production of electricity, the steam turbine is coupled to a generator, which is commonly referred to as a steam turbo generator set. Leandro says

High pressure efficiency Building on its success with ELGi’s range of high pressure, diesel-driven compressors, Integrated Air Solutions has introduced the ELGi EG Series of electric air compressors.

ELGi’s electric screw air compressors are available from 5.5kW to 15kW for smaller air requirements (EN Series) and from 22kW to 250kW for medium and large applications (EG Series).

Reduced pressure losses and increased efficiencies are what most customers are looking for in a compressor and the ELGi electric range has been designed with that in mind. Packed with state-of-the-art technologies, these compressors present a giant leap in design and performance from the unique encapsulated airend (EN Series) to the efficient three-stage air-oil separation system.

“The result is a compressor that delivers air efficiently and reliably with minimum pressure drop. This, combined with a low lifecycle cost, places the benefits of a lower total cost of ownership in the hands of customers and end-users,” says Trevor Volker, Integrated Air Solutions product manager for electric compressors.

Airend encapsulates all major functional systems such as intake, compression and separation within a common frame, ensuring silent operation. The efficient three-stage air-oil separation system reduces oil particles to less than 3ppm.

The robust air-cooling system comprises high efficiency coolers and cooling fans to ensure low operating temperatures,

extending compressor life. The two-stage air filtration system facilitates air to enter through a pre-filtered enclosure, thereby enabling cleaner suction which keeps internal components clean and increases the life of consumables.

Securing railway coaches BMG supplies the local railways sector with custom-designed planetary gearboxes for use in railway maintenance programmes.

“Dinamic Oil gearboxes, which are supplied with 22 kW brake motors, are used to lift, turn and hold railway coaches securely in place during maintenance procedures, like welding and machining,” says Kelly Mac Iver, gears manager at BMG. “A notable feature of this system is enhanced safety during operation. Prior to the introduction of these planetary gear units, large overhead cranes were used for lifting, turning and holding during maintenance and which was a highly dangerous operation.”

These planetary gear units have a nominal output torque of 210 000 Nm and turn 15 ton railway coaches at 1rev/min. Other advantages of these energy-saving units include efficiency at low RPM’s, easy access for maintenance, a smaller box for a given load and a wide range of ratio permutations.

Environment friendly lubricants In a rapidly changing global climate and with every industry under pressure to mitigate environmental damage, even wire rope lubrication can play its part.

Engineers South Africa, explains that in the maritime sector, having a non-toxic lubricant for wire ropes, moving chains and cable parts is particularly important for preserving marine life.

Wire ropes need to be well lubricated to withstand increasingly harsh climate conditions, especially in the maritime and mining industries, but the lubricants used on them can negatively affect the environment. Products are now available that help to minimise adverse effects.

While environmentally friendly lubricants have long aimed to be biodegradable, the value of products like the Earthwise range supplied by Lubrication Engineers (LE) is immense because of its focus on non-toxicity. LE’s Earthwise EAL Wire Rope Grease (3353) is a certified environmentally acceptable lubricant and is recommended for use in applications on or near waterways. It is readily biodegradable, exhibits minimal aquatic toxicity and will not accumulate in the cells of fish and other aquatic life forms.

Llewellyn Owen, National Marketing Manager for Lubrication

LE also supplies a wire rope lubricant, Wirelife Almasol Coating Grease, for the mining sector.

This lubricant is highly tacky, ensuring that it sticks to the rope and doesn’t fall onto the ground and affect the earth’s surface where it is used.

Robots slash document reporting time While the manual compilation of a Safety, Health, Environment and Quality (SHEQ) documentation reporting can take up to 20 man hours, Passport 360 has slashed this time to three minutes.

This is thanks to built-in Robotic Process Automation (RPA), which allows for custom documentation to be compiled in mere minutes. “It provides for a greater level of real-time intelligence and insight into SHEQ,” Passport 360 Director and Co-Founder, Siobahn Whitehead, comments.

In addition, the dashboard view feature consolidates all contractor SHEQ documentation into a high-level dashboard, again for real-time access of all data, which can be managed and interpreted accordingly.

Without consistent monitoring and review, SHEQ information quickly becomes outdated, thereby ramping up the risk considerably. Digitising these records and then applying Passport 360’s built-in RPA allows for mining operations to better pursue the industry’s ultimate goal of zero harm.

This also has significant implications for clients in terms of transparency and security, Siobahn highlights. “Passport 360 allows contractors to access client systems and information without exposing those internal systems,” she concludes.

Saving screens with high-quality motors Harsh operating conditions on vibrating screens demand high quality engineering and the strictest tolerances for unbalanced motors and gearboxes, or they simply do not last.

Kenny Mayhew-Ridgers, chief operating officer at Kwatani says, “We design our own motors with local conditions in mind, giving the customer a high performance and long lasting product.”

This includes optimal sealing arrangements for keeping electrical components dry and clean. The design must consider various orientations of the motor, depending on the angle of installation. Dusty conditions on mines also present a challenge.

“Dust ingress can compromise the sealing configuration of the lid,” he says. “Our design is therefore like a top-hat, so the O-ring is not on a flat surface but rather on a cylindrical, vertical surface.”

He also highlights the massive centripetal forces that are exerted on the screening machine by the unbalanced motor and gearbox. This makes it vital to secure them well to the screen.

“To achieve this, we specify our own fabricated bolts, nuts and washers,” he says. “If sub-standard fasteners are used, components can come loose and cause extensive damage,” concludes Kenny.
