Saving energy and protecting the environment with the right compressed air solution

With Europe experiencing soaring energy prices, and compressed air accountable for between 12 to as much as 40 per cent of all the industrial energy consumed[1], many businesses are considering what steps they can take to minimise costs and improve the efficiency of their operations. Now is an opportune moment for energy-intensive organisations to take advantage of heat recovery, oil-free technology and digital analytics, says one of the industrial compressed air leaders, CompAir.

In the first quarter of 2022, short-term gas prices on the largest European exchange were five times higher than their 2021 average[2], and future markets are pricing European gas at up to three times its 2021 levels for at least the next three years. However, CompAir is advising compressed air users that action can be taken now to help protect their investments for the future.

Here are some top tips that CompAir recommends, with advice on the company’s latest compressed air technologies, to help lower energy costs and optimise efficiency levels.

 

Opt for oil-free screw compressors

While most production-sensitive environments, such as those in the food and beverage or pharmaceutical sectors, will opt for an oil-free compressor, many other businesses would benefit from the efficiencies that an oil-free model can deliver. In many cases, whole life costs are reduced, with businesses able to save on the cost of oil replacement, and there’s no requirement for additional products such as oil separators.

CompAir offers a wide range of oil-free compressor technologies, including screw and piston machines.  Its advanced Ultima compressor operates completely oil-free, with the cooling of components achieved via a closed water circuit.

Each airend is driven individually by a variable speed, permanent magnet synchronous motor, offering exceptional levels of efficiency versus traditional oil-free technology.

Take advantage of the latest oil-lubricated screw compressor technology

However, for those seeking an upgrade to an oil-lubricated system plus air treatment, the latest oil-lubricated technologies have been developed to optimise sustainability throughout the compressor’s lifecycle. CompAir’s FourCore range combines best-in-class compressed air efficiency with a small footprint and sustainable design for eco-conscious businesses.

For example, when carbon emissions from a new 160 kW FourCore model are compared with a traditional compressor, running for 8,000 hours a year, the FourCore system reduces the equivalent greenhouse gas emissions of 32 passenger cars, or 371,800 miles driven by a passenger car, over the course of one year. This is the same amount of carbon sequestered by 181 acres of forest.

Furthermore, when compared with a conventional two-stage compressor, the new 200 kW model uses 22 per cent less materials and can help cut waste by up to 19 per cent.

And when compared with previous single-stage compressors in this size range from CompAir, the new models are up to 8 per cent more efficient, offering a best-in-class oil-lubricated solution for decision makers.

Treat air correctly

Modern production systems and processes demand compressed air of ever-increasing purity. The proper specification of downstream equipment will not only further improve the quality and efficiency of a compressed air system but reduce its environmental impact too.

CompAir offers a wide range of compressed air treatment solutions including filtration, refrigeration and absorption dryers and condensate management systems. High-quality consumables, such as filter elements with a long service life, ensure low component wear and consistently low differential pressure.

Heat recovery

Meanwhile, taking advantage of measures such as heat recovery represents a considerable opportunity to lower energy costs, by recycling excess heat and using it to a site’s advantage. With typically only 10 per cent of the electrical energy input being converted into compressed air, the remaining 90 per cent is generally wasted as heat. By fitting a heat recovery unit to a compressor, the system can ‘recapture’ energy lost during the compression process and use it for other useful purposes. For example, it can supplement the electricity, gas or oil needed to generate hot water for washrooms or process water. Alternatively, it can be transferred as direct warm air into a workspace or facility.

CompAir offers multiple turnkey heat-recovery solutions for its oil-free and oil-lubricated screw compressors, both factory fitted and retrofittable. This allows for easy ‘plug-and-play’ installation and an immediate realisation of energy and cost savings.

Drive improvements with digital insights

The Internet of Things and data analytics can help operators to understand how efficiently a compressor is running, and whether any improvements can be made. These insights will not only help highlight any potential issues now, but also enable operators to forecast any potential future problems, based on deteriorating machine performance.

Predictive maintenance models based on real-time data can be established to help reduce energy consumption, improve process efficiencies and limit any risks. Connectivity continues to be a key focus in the CompAir portfolio, with the company’s iConn service offering intelligent insights that help operators monitor a system’s performance in both real-time and remotely.

 

Accessible from smartphones and tablets, the browser-based system ensures users can proactively manage any potential issues that arise at all times, reducing associated downtime and guaranteeing the system is performing as required.

Guaranteed assurance with service agreements

To help companies avoid unplanned and unbudgeted downtime, as well as production interruptions, CompAir has launched a series of new Assure service agreements. Available to all compressed air users, no matter the manufacturer or age of the equipment, these help businesses optimise operational efficiencies, mitigate risks, and streamline working practices by ensuring customers only need to deal with one compressed air supplier.

From the entry level, AssurePLAN, which covers the timely replacement of consumable components such as oil and air filters, separators, and oil, with a 12-month warranty on these assets, to the most comprehensive, AssureCOMPLETE, which ensures all operational risk for a compressed air system is transferred to CompAir, a service agreement is available to meet a business’ exact needs.

In addition, these agreements include genuine spare parts. While a non-genuine part may be cheaper, it can compromise the compressed air investment in the long run and end up costing a business more. In contrast, genuine parts are manufactured to meet the same high standards as the compressors they are intended for.

 

Don’t leak profit

It’s essential to manage pipework leaks. Air leaks are the leading cause of energy loss in industrial air systems, wasting as much as 20 to 30 per cent of the system’s output. There are many reasons for leaks in a compressed air system, including shut-off valves and manual condensate valves being left open, as well as leaking hoses, couplings, pipes, flanges and pipe joints.

With a leak as small as 3mm potentially costing over €800 in wasted energy[3], one solution is a simple leak detection survey, which can identify any problems quickly so remedial action can be taken. Alternatively, a flow meter is a reliable means of evaluating compressed air generation and downstream inefficiency costs. Indeed, finding and repairing one 3mm leak could potentially save enough money to cover the cost of purchasing one.

Undertake an energy audit

Whether it’s buying a new compressor or upgrading an existing system, a sensible starting point is to always undertake a full site energy audit. This will establish current compressed air usage and costs, help identify air leaks to determine where energy is being lost and where cost savings could be made, and test air quality to ensure the compressed air generated meets the right standards. Not only does an energy audit help lower a business’ total cost of ownership, it also helps reduce environmental impact too.

Sandvik CRIBWISE launches white paper to help tackle cybersecurity in machine shops

Sandvik CRIBWISE, the tooling inventory management software business, has published an in-depth white paper addressing the cybersecurity concerns of machine shops that are preventing the adoption of the latest technology, including cloud-based software.

Elvira Cedergren, Head of cybersecurity at Sandvik’s Design & Planning Automation division, which includes CRIBWISE, explains how machine shop vigilance needs to start with the basics after escalating cyberattacks over the last year.

The white paper addresses cybercrime, specifically for manufacturers, and the straightforward, common-sense steps that can be taken on-site to protect machine shops of all sizes.

Elvira says: “Supply chain attack which affected 40,000 businesses worldwide and infected over a million systems, caused a lot of disruption last year. It is a myth that criminals only target large businesses; cybercrime can affect all businesses, both large and small and it is necessary to have basic processes in place to mitigate risk.”

Elvira’s insights in the white paper, will reassure manufacturers reluctant to move to digitalisation as it outlines the questions that should be asked of vendors at the procurement phase to mitigate risk.

She adds: “It is natural for businesses to be wary about investing in cloud-based software and services that run on the Internet. After all, if you limit the exposure of your business to the Internet, you also limit your exposure to the criminals that inhabit it. You would, however, also be seriously limiting the potential of your business to grow. Systems like CRIBWISE are invaluable tools for improving operational efficiency and reducing costs. There are advantages of adopting cloud-based systems —both from security and productivity perspectives."

She concludes: “Cybercrime should be taken seriously and there are simple processes that businesses can take, on-site, to protect its machine shop. A responsible software company, like CRIBWISE, takes a great deal of pride in the levels of security it provides its customers. This white paper provides clear and practical advice that can protect CNC machines and other systems, so that manufacturers can reap the benefits while still protecting its supply chain and business.”

CRIBWISE helps manufacturers to take control of their tooling inventory and related processes. It is modular, customisable and easy to integrate for all sizes of machine shops. It helps improve productivity and machine life by reducing administrative time, hours spent searching for tools and production and maintenance delays. It also cuts unnecessary expenditure due to over-purchasing and over-stocking. 

Head of CRIBWISE, This email address is being protected from spambots. You need JavaScript enabled to view it., says: “The pandemic has led to manufacturers really embracing cloud-based solutions over the last couple of years and are seeing the cost-saving benefits from reduced tooling and equipment inventory costs. Some companies have seen costs go down by as much as 20%.

He adds: “Manufacturers should be concerned about cybersecurity but by planning and understanding how to manage any potential risk, businesses should embrace new technology and cloud-based software. This will undoubtedly help businesses stay competitive in challenging times.”

Whitepaper shows how EAM technologies can help logistics operators tackle the threat of downtime

Ultimo has published a new whitepaper to help logistics businesses optimise uptime and cut costs. According to a recent survey (EAM Trend Report 2021), 42% of asset managers in the logistics sector suffered unplanned downtime last year. Worryingly, only 4% knew how much downtime cost their organisation, highlighting the risks inefficient maintenance practices and lack of operational data pose to profitability. The whitepaper explores these challenges and explains how leveraging the latest Enterprise Asset Management (EAM) technologies can help give logistics managers better control over the cost and performance of fixed and mobile assets.

Logistics sector: Vulnerable to risks

“The logistics sector is very vulnerable to the risks associated with downtime, as any incident can quickly escalate down the supply chain,” says Chris van den Belt, Team Leader Project Management, Ultimo. “Access to reliable asset data is vital for mitigating these risks and protecting profitability. However, 56% of logistics managers lack the data they need to benchmark performance, making identifying and correcting inefficient and costly maintenance practices difficult. The figure is high compared to many other sectors, highlighting the urgent need for the logistics industry to adopt a more data-driven approach to maintenance. This whitepaper highlights the issue and explains why data needs to play a key role in all futureproofing efforts.”

What are the causes of downtime – and how to address them

The whitepaper explores typical causes of downtime in the sector, such as ageing assets and poor communication between teams. It then explains how operators can leverage cloud-based EAM technologies to address them, reducing risks and cutting costs.

It also discusses why operational data is an invaluable tool in helping improve knowledge-sharing – a crucial step in enhancing the response to unprecedented events, mitigating the challenges associated with experienced workers retiring, and bridging the emerging skills gap in the industry.

Waste to Energy Plants Suffer from Unplanned Shutdowns Caused by Boiler Failure

A 2021 Prewin Network Unplanned Shutdown Survey has revealed that equipment failures in Waste to Energy (WtE) and Biomass plants were responsible for a total of 22.9 days of unplanned shutdowns in 2021, and 43% of equipment failure classifications were boilers.

Over 43 per cent more gas (!) as Hayley Group wows customer with new AD/Biogas mixing system

A leading food waste-to-energy operation has increased its biogas yields by an average of more than 43% - due to a new digester mixing system.

 After evaluating the performance of the facility’s first digester, built a decade ago, engineering component specialists Hayley Group were consulted about the availability of an alternative, superior mixing system for its customer’s second digester; mixers that unlike those in first tank, would eliminate typical biogas process problems such as foam, blocking and crusting – and in doing so, help boost the levels of methane.

 Hayley Group’s Engineer, Rob Bentley, said: “We constantly look to help customers improve efficiencies. This project is of particular note, because with the new, superior mixing system, the increase per cubic metre in gas from the second digester is over 40%. This is extremely encouraging to say the least, especially when you consider that the second digester also has 10% less capacity than the older first tank”.

Anti-slagging Boiler Coating Facilitates Fuel Diversification

Introduction
In 2020, a large power generation company in Southeast Asia commissioned the production of a new 600MW Pulverized Coal (PC) Boiler at its plant. The company had a requirement to be able to burn the full range of its coal, which had proved challenging due to the high calcium content of the fuel. As a result, a new boiler had been built and commissioned by a reputable manufacturer.
Since the boiler has been in operation, the plant has suffered with a build-up of slagging on the tubes. The plant’s requirement to burn the full range of coal means that some ranges had to be burned at an increased temperature, which had been causing excessive slagging at the bottom of the boiler. To fix the problem, the build-up was being regularly blasted, which was time consuming and inefficient.

The Issue of Boiler Slagging

Pulverized Coal boilers experience slagging as the molten ash adheres to the surrounding substrates. This is also commonly referred to as slag. The amount of slag is primarily dependent on temperature and the types of coal being used and whether it is anthracite, bituminous coal, subbituminous coal, or lignite. Boilers will often slag in the upper sections of the furnace where the temperatures are higher near the superheat pendants, but slagging may also occur on the waterwalls. The build-up has a negative effect on boiler operation. The slag acts as an insulation to the tube substrate and this loss of heat transfer is detrimental to performance. When the slag builds up on the tubes, the heat transfer decreases lowering the temperature of the steam going to the superheated portion of the system, therefore decreasing the overall efficiency of the system. Finding a solution to excessive slagging can have tremendous benefits for a boiler operator’s bottom line.

No more FOG, as major crust problem caused by Fats, Oils and Greases is defeated

Throughout Ohio there is a large a number of meat/food processing plants and municipal sites whose wastewater system is plagued by fats, oils, greases (FOG) and debris. 

Many of these may already have some sort of pump/mixer - perhaps sold on the basis of it being supposedly ‘non-clog’ - but staring down at a tank crusted over so badly that you might not be able to see any wastewater, tells you immediately that this isn’t the case. Chances are that the odor from the tank/collection system is so bad that even a new visitor to site - blindfolded – could locate it in seconds.

A classic example of this came to light just recently, when a leading meat processor, bogged down by reoccurring costs, foul odors and poor performance of its wastewater treatment system, looked for a cost-effective, long-term solution.

The problem at this particular site was so bad that you could (not that anyone in their right mind would) walk on or jump up and down on the layer of the tank’s crust because it was so thick!

Pressure on for safe cleaning

The Water Jetting Association is introducing a new code of practice for pressure washing to counter ignorance about the risks associated with the cleaning technique and to improve safety for operatives and others in the workplace.

The code lays out, in plain terms, the steps needed to optimise the safe use of pressure washing equipment. It also explains why these steps are important and what needs to be done if something does go wrong.

The Water Jetting Association (WJA), the UK’s trade body for the water jetting industry, says awareness of water jetting risks has not, until now, stayed in step with the development and increasing availability of pressure washing technology.

WJA Training and Safety Committee Chairman Darren Hamilton said: “Over recent years, companies and individuals have been able to buy evermore powerful pressure washing systems.

“However, many people don’t realise the risks they face if they don’t handle this equipment properly or if it malfunctions. Our new Pressure Washing Code of Practice addresses these issues, giving users of this very useful technology the guidance needed to work safely at all times.”

The WJA points to incidents like an experienced operative who suffered severe injuries, including 4th degree burns, when a 3,000 pounds per square inch pressure washing jet pierced his boot, filling it with 1100C water.

This incident is just one of many pressure washing injuries. In another, a dockyard operative slipped due to the unexpected power of a pressure washing jet, allowing the nozzle to swipe across his supervisor, lacerating his upper thigh.

The WJA has already developed two codes – the Blue Code for high pressure and ultra-high pressure water jetting, and the Red Code for water jetting used for drain and sewer cleaning.

The new pressure washing code will support safe and productive water jetting at lower pressures, introducing a new operational standard and health and safety support for companies and agencies that carry out pressure washing and who rely on its advantages.

The code of practice gives the WJA’s definition of pressure washing, or power washing as it is also called. This is any jetting activity with a water pressure of up to 3,000 psi, or 207 bar (20.7 MPa).

Pressure washing is used to clean equipment and machinery in factories and engineering environments. It is also used to clean brickwork, remove graffiti, and clean mud and oil from the carriageway during highway repairs and construction.

In all these tasks, without a clear operational framework that a code of practice provides, there is opportunity for field teams to improvise and develop both unsafe and suboptimal practices.

The new code of practice includes sections on training and competency, site and equipment set-up, and the different types of pressure washing pumps and equipment, including hot water systems.

There is detailed advice on risk assessment, including a pre-start checklist, and emergency first aid specifically for the risk of fluid injection injuries that can be sustained during water jetting.

The WJA is the UK’s main provider of water jetting training. This includes a City & Guilds accredited pressure washing course which lasts at least five hours and is delivered by WJA-approved training providers and instructors.

Pressure washing contractors who are WJA members have welcomed the new code of practice, which is due to be published in early 2022.

Kris Jasinski, owner of TPC Brickwork Cleaning, in Southampton, said: “Having a code of practice to work to will benefit our industry greatly. People will be able check that standards are being set. The advice the WJA gives is central to how we go about our work and to our business success. I have no doubt about that.”
