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.

Atlas Copco Rental assists temporary hospital in Italy

Fiera Milano is home to some of the most prestigious exhibitions in the world. But, with all events canceled right now, the space is still being put to good use. A new hospital, designed specifically to treat patients with Covid-19 is being set up.

The “Fiera” Hospital was commissioned by the Lombardy Region (Italy) and is a full-fledged hospital.

When finished, the facility will have more than 400 intensive care units. Once operational, it is expected that 500 nurses and 200 medical professionals will be working and treating patients here, that will come from all over Italy.

The temporary hospital is a source of inspiration and hope, as well as determination.

The Italian government is also considering to replicate what was done here in Milan, and build more temporary intensive care facilities in the center and south of Italy. Regions which are also greatly affected by the Coronavirus pandemic.

For an indefinite period of time, our GA75 VSD+ FF will be a vital part of providing the hospital’s Medical Gas Supply. These systems typically include oxygen, nitrogen, carbon dioxide, nitrous oxide, etc.

Temporary solution for temporary site

We were able to surpass our customer’s expectations thanks to the high efficiency of our equipment.

The GA75 VSD+ FF is capable of providing a maximum flow of 956,88 m³/h at bar. It is equipped with a Variable Speed Drive+, a powerful motor and has a compact footprint.

The GA’s Variable Speed Drive+ (VSD+) technology closely matches the air demand by automatically adjusting the motor speed. Combined with the innovative design of the iPM (Permanent Magnet) motor, this results in substantial energy savings. Even when it is on-site only temporarily, you can still expect the most sustainable solution. Besides that, the GA series is ISO 9001, ISO 14001 and ISO 1217 compliant.

Atlas Copco Rental Russia keeps air oil-free at sub-zero temperature

From extreme temperatures, both high and low, and the most remote locations, our equipment can be found all over the world. In this case, working conditions were pretty cold, to say the least. Gloves: check. Scarf: check. Winter coat x 2: check. Here we go!

Our client specializes in construction services in the oil and gas industry. When a section of pipeline needed repairs and partial replacement in Northern Russia, we provided Atlas Copco Rental equipment that was capable of working in sub-zero temperatures as well as meet all expectations. Working parameters ranged from 10 bar to a potential increase of up to 80 bar, so we came up with a unique solution that was up for the task, every step of the way.

  • 100% oil-free air PTS 916 compressor
  • CD41 dryer
  • Nitrogen generator
  • 4 high-pressure and diesel-driven XRVS compressors with different specifications

Before the pipeline can be used again, a mandatory integrity check has to be performed. In this case, it was possible to perform a hydrotest. Water is used to put the section of pipeline under extreme pressure, far higher than the operating pressure, and make sure it is compliant with all applicable rules and regulations. In order to perform the test, a constant supply of water is required. Nearby water supply was too limited and would have had too big of an environmental impact when these would have been used. So a secondary pipeline, of around 2 kilometers was then constructed to reach a small river. Because it was winter, you can imagine this came with its own challenges. After the hydrotest was successfully completed, the pipeline needed to be dried and cleared of any remaining air, debris. This is where our high-pressure compressors and boosters come in. Usually after dewatering a pipeline, some water remains in the pipes. Dry air goes under pressure into the pipes to absorb the remaining water in the pipeline. Then nitrogen purges the pipelines of all remaining air. These procedures are essential. Not only do they displace the oxygen, but they also delay oxidation and avoid explosions by not allowing air and natural gas to mix in dangerous concentrations. Nitrogen generators with different flows and purities are matched with compressors to reach the required nitrogen pressure and flow. Soon after passing all tests, the pipeline was up and running again!

Rand-Air’s MIRS training investment – ‘generating’ the power behind top-quality staff

In the 45 years since Rand-Air’s inception, this market-leading compressed air and generator rental business has not only maintained a stringent focus on the quality of its products  and customer service – but also the quality of the people who provide the critical interface between the company and its valued customers.

To ensure that customer service and relationships are always fully optimised, and to support its employees’ efforts in this regard, Rand-Air invests substantially in ongoing training and development – across all relevant disciplines – including technical, safety and rental marketing.

Further to these initiatives, Rand-Air – together with Atlas Copco’s rental division – have devised a challenging MIRS (Master in Rental Sales) training programme which is used to develop promising talent in the organisation.

In 2017, an international MIRS training course was held, composed of 16 promising, high-potential sales engineers. Denise Olivier, a Rand-Air external sales representative based in the town of Kathu in the Northern Cape was selected to attend. Over a period of six months, she attended the four one-week MIRS training modules in Thailand, Belgium, Brazil and Dubai.

“It was a very intensive course, with a lot to take in and to put into practice. However, I have done so this year, and will increasingly benefit from this training as time goes by,” explains Olivier, who joined Rand-Air four years ago. She explains that the training has helped her significantly.

“To me, it is all about building that vital relationship with our customers, and ensuring they have a really excellent experience of our solutions and our service,” she affirms.

During the MIRS programme, Olivier was taken through the building blocks of the sales process. Rand-Air is keenly aware of the need for a wide range of skills required by a fully professional salesperson, and for this reason, makes every effort to ensure that every one of these salespeople is as well-equipped as possible to meet the challenges of working in the field. Each of these building blocks represent one of the essentials steps that need to be considered when approaching, presenting or concluding a sale. A key component of this is gaining a precise understanding of the client’s needs and then ensuring that these requirements are met to the letter.

“This training is very practical, as participants gain knowledge in both ‘hard’ and ‘soft’ skills; which equipped us with all the right tools and knowledge to further boost our customer relationships and ultimately, our performance,” she explains.

The training was offered by internal specialists and external trainers. The internal specialists focused on the essential ‘hard skills’ – which covered such as products, applications, segments and sales tools, among others. The external trainers presented courses on the indispensable ‘soft’ skills’, which are equally essential at every stage of the sales process.

During each session, the in-country hosting team shared their regional best practices, such as local success stories with product and segment insights, usage of sales tools and tailoring sales efforts to ‘fit’ the local market and environment.

With each module, participants grew from being a ‘sales representative’ to ultimately graduate as  a fully-fledged Rental Master.

Besides the essential skills and learning which they gained, participants were also tasked with reporting on their own personal development.

During the final graduation ceremony, each participant received an 18-month mission statement. New graduates who reach their targets will be invited for a fifth module, to take a ‘next step’ in their competence development.

Olivier explains that, based as she is in Kathu – a relatively remote branch in the Northern Cape – she has to be an all-rounder, ready to step in wherever she is needed.

“This depot feels to me like it’s my own business, so I go the extra mile. I am always on standby – customers sometimes call me with emergencies at three o’clock in the morning, and I will be there helping as best as I can,” she adds.

“One thing I have learned is that, after the MIRS training, I am more than a sales representative – I am now a Rental Master and sales professional,” she asserts in conclusion
