Atlas Copco Rental provides large volumes of compressed air – fast!

When a global leader in specialty chemicals needed help generating large volumes of compressed air — with extremely little time available for getting the needed equipment in place — Atlas Copco Rental had a powerful answer, and was able to provide it quickly.

After the company’s chemical facility in northeastern Mississippi suffered a stationary compressor failure, the need for supplemental air was urgent — without it, the plant would have to be completely shut down. Time was of the essence, and only the right equipment could meet the need.

A successful solution

Fortunately, Atlas Copco Rental’s Covington, Georgia, branch had the needed equipment on hand, and could get it to the plant on short notice. Personnel from Atlas Copco Rental delivered and installed a ZH 9000 oil-free centrifugal air compressor within 10 days of getting the call.

Provided as a plug-and-run package, the ZH 9000 was delivered directly to the worksite in its integrated, 40-foot-long, weatherproof transport container to become a stand-alone mobile air power plant, with only electrical and water hookups needed for the equipment to spring into action. Once placed, the high-volume compressor was capable of providing compressed air at 140 psi (10 bar), offering a maximum flow of 9,000 cfm (254.9 m3/min) — and could do so with an energy-saving design and guaranteed reliability. Further, the provided unit was able to meet needs for constant air or could handle processes with fluctuating air demands. And with its ISO 8573-1 Class 0 certification, the 100% oil-free air supplied by the ZH 9000 was guaranteed not to contaminate the plant’s end products.

When the client needed powerful, high-quality equipment in a short period of time, Atlas Copco Rental met the need fast — and kept the plant’s work on track.

Capitalizing on synergies to commission Omani plastics project in record time

Getting process piping ready for commissioning typically involves a complex array of tasks. And since they usually come at the end of an equally complex construction process, those tasks also typically involve extremely tight deadlines!

In such situations, being able to count on a reliable partner with a proven track record often means the difference between making or missing your project deadline. So it’s little wonder that GS Engineering & Construction called on Atlas Copco Rental to work around the clock – and often against the clock – to help complete their contribution to Oman’s ambitious Liwa Plastics Project.

A high-profile project

The Liwa Plastics Industries Complex is the cornerstone of a major expansion project within the Suhar Industrial Port Area refining and petrochemicals cluster. Once operational, it will not only boost Oman’s export trade but most importantly, stimulate the development of a whole new downstream processing industry within the sultanate. As such, this flagship project has been the subject of considerable media attention. As the main EPC contractor for the project, GS Engineering & Construction was under significant pressure to deliver the project on schedule.

Multiple challenges

GS Engineering & Construction is responsible for the construction of a NGL extraction plant within the Liwa complex. The plant had already incurred significant delays during the construction phase. Now the South Korean-based contractor faced an uphill battle to fast-track the commissioning phase and get the project back on schedule. The lack of time, however, was not the only obstacle in their path. Getting the plant online meant performing multiple testing and commissioning tasks simultaneously. Which in turn meant that demand for the nitrogen and other gases required for drying, purging and pressure testing was difficult to predict and subject to significant fluctuations. On top of that, the plant’s remote location ruled out the possibility of obtaining a sufficiently stable supply of liquid nitrogen. And so an urgent request for quote was launched.

One solution, multiple applications

GS Engineering & Construction came to us with an urgent request for equipment and personnel to perform a wide array of functions. From air blowing and dewatering to purging and high-pressure leak testing… These diverse tasks all call for different gases at a wide range of pressures, flow rates and levels of purity and dryness. Nevertheless, we were able to propose a flexible and modular solution that capitalized on certain synergies to complete the project effectively, efficiently and most importantly, on time.

Area Rental Supervisor Qatar & Oman, Atlas Copco Rental Middle East

The required 8,000m3/h of dry, oil-free air required for air-blowing and dewatering, for example, was delivered by a package of 3 x PTS 916 100% oil-free air compressors which worked in tandem with 3 x PHS 1600 dryers. At the same time, 3 x XRVS 1000 compressors fed our state-of-the-art NGM 2000 mobile nitrogen-generating membrane package for purging the plant’s tanks and process piping.

This same package was also used for a comprehensive high-pressure leak test thanks to the addition of a B7 nitrogen booster, delivering the required 1,500m3/h of 98% pure N2 at an impressive 100 bar of pressure!

The solution also included all accessory hoses, manifolds, fuel tanks and so on, as well as an on-site team who took care of transport, assembly and round-the-clock operation for the duration of the project.

Clear added value

Our solution for a reliable, stable, cost-effective and fully mobile source of dry, oil-free air and pure, high-pressure nitrogen proved to be a critical element in completing the commissioning of the Liwa plant successfully:

We compared multiple options during the bidding stage. Finally we selected Atlas Copco Rental’s nitrogen generating membrane package because it was much more effective and economical.

Commissioning Lead Engineer, GS Engineering & Construction.

What really earned us the praise of GS Engineering & Construction, however, was our speed and efficiency at every stage of the project. From our quick response in providing a quotation to the flexibility and versatility of the solution itself and the expertise and proactivity of our on-site operators… Our local team ensured that every single piece of the puzzle fit together with precision, and always with a view on the bigger picture.

A long-standing partnership

The Liwa project is just a part of a long-standing partnership with GS Engineering & Construction in the Middle East. And it was yet another opportunity for us to demonstrate that we not only have the state-of-the-art equipment they need to get the job done, but also the knowledge, expertise and experience to add maximum value to their large-scale projects. We are already looking forward to the next challenge!

Maximum performance with minimum downtime for Chinese chemicals plant

How do you purge and dry a 660,000 ton/year propane dehydrogenation unit and 400,000 ton/year polypropylene unit without electricity? That was just one of the challenges put to Atlas Copco Rental by its customer, a downstream chemicals plant as part of a large-scale maintenance operation. The other? Speed!

Fortunately, we are well accustomed to working against the clock and under challenging conditions. And when you put superior technology and the unwavering dedication of our local team together, anything is possible.

Against the clock

“Time” is and always has been “money”, no matter what industry you’re in. But in today’s extremely competitive downstream chemical processing sector, the old adage seems to be doubly true.

So when planning a maintenance operation of this magnitude, finding a fast, efficient and reliable solution was a top priority. But drying and purging the plant’s enormous production units on schedule meant being able to deliver an extremely high flow of oil-free air of 80m3/min.

Dryer than dry

In addition to the high output requirements, the resulting air flow also had to be extremely dry to avoid compromising the propane dehydrogenation unit’s distillation system during maintenance. To put it in perspective, the moisture limit of 1 part per million (with dew point of maximum -80°C) is around 5000 times dryer than the air above the Sahara Desert!

On the move

To complete the entire operation on time, the plant also decided to perform the necessary maintenance on its power lines at the same time as the rest of its systems. This meant that our solution also had to be fully self-sufficient as well as portable and weather-proof, to be able to service the plant’s numerous components spread over a significant surface area.

Cutting-edge technology

With all these constraints in mind, the project represented yet another opportunity for us to demonstrate the industry-leading performance of our diesel-powered PTS 1600 oil-free compressors.

The package designed by our local team comprised 2 PTS 1600 units in tandem with 2 adsorption dryers (the PHS 1600 and CD 760), 2 after-coolers and 1 cooling tower.

The solution well and truly met the customer’s strict requirements in terms of flow rate, air purity, dew point and dryness.

One satisfied customer

This was the first project we had the pleasure of delivering for this particular customer. And it took multiple presentations and technical meetings and all of our Rental Sales engineer Hyway Zhang’s skill, knowhow and perseverance to secure the business:

The customer was extremely satisfied with the performance of the two compressors and the seamless commissioning of their systems following maintenance. They were especially pleased that we could help them reduce maintenance time with around 7 to 10 days. So much so, in fact, that future collaborations are already in the pipeline!

This successful project is just one of many that have contributed to Atlas Copco Rental’s strong and long-standing reputation in China’s downstream processing industry.

Oil-free air used for the Great Bubble Barrier in Dutch waterway

When we think of bubble curtains, large offshore applications are usually the first thing that come to mind. However, the possibilities are not limited to the vastness of our oceans. The Great Bubble Barrier uses the same concept, but scales it down to local waterways, offering a smart solution to plastic pollution.

Plastic not so fantastic

Plastic waste is not something we only find on the other side of the world, or in the ocean. It is present in local waterways as well, where it brings great harm to the environment and human beings. Aquatic animals are tangled in plastic, microplastics pose a health risk from the smallest to the largest organisms and ships suffer damages. Different institutions worldwide, such as the United Nations, Ellen McArthur Foundation and the World Health Organization, recognize this increasing problem.

The Great Bubble Barrier has designed a solution that intercepts plastics in rivers and canals before it reaches the ocean.

For a large part, the way The Great Bubble Barrier uses the Bubble Barrier, is similar to what is used for offshore projects. However, there are a few differences. For example, the barrier is placed diagonally in the waterway, allowing it to use the natural current to guide the plastic to the catchment system at the riverside. Both ships and fishes can pass the Bubble Barrier, but plastic will be stopped. Besides the capture of debris, the Bubble Barrier has other positive side effects. Oxygen levels within the water increase by a Bubble Barrier, which stimulates the ecosystem and stops the growth of toxic blue algae.

Bubble it up

For the creation of the bubble curtain, Atlas Copco Rental installed an electric driven oil-free air compressor. The advantages of this energy-efficient solution are a fast start-up and low noise during operation.

The role of oil-free is vital for environmental reasons as the air is in direct contact with the water. There is no point in risking environmental oil pollution. Even the smallest quantities could have lasting, harmful effects on local marine life.
