PLANTSERV® Lifetime Extension in Conjunction with Energy Transition
Special edition: Discover our solution in practice and see how you too can unlock new business opportunities.
Our seamless, comprehensive service portfolio takes the complexity out of challenging projects balancing revamps with machine electrification.
With a focus on emissions abatement, governments are tightening regulations all over the world. For plant owners and operators, revamps are a good opportunity to decarbonize their assets and ready them for the future. Yet revamps are often quite complex, with a favorable outcome depending to a large extent on careful planning, engineering excellence and expert project management.
Many such projects focus on changing the energy source for ASU compressors from steam to electricity.
“Generally speaking, steam to electricity is very complicated revamp work, though an extremely effective way to decarbonize,” says
Guoping Yang, Head of PLANTSERV® APAC.

Lifetime Extension in Practice
Modernize your plant for added value, extend service life or even relocate your asset with our holistic lifetime solutions. Our expert team is dedicated to finding solutions for your unique requirements – from minor modifications to complex, full-scale projects requiring utmost precision and quality. For younger plants, we develop revamp concepts to enable growth, meet increased customer demand or adapt to specific new market or legislative requirements.
Our PLANTSERV® engineers start with a detailed investigation of your process plant to assess the viability and potential savings of a revamp. Factors such as market demand, plant design, site conditions, operability and cost-effectiveness are taken into consideration. This is followed by a feasibility study to define the best solution, balancing constraints such as shutdown windows, constructability, budget, OPEX and other operational requirements.
In a recent project, the customer was keen to maximize the use of existing infrastructure and equipment, which was in the middle of its useful life. Our team grasped the opportunity to also exchange the compressors, thus increasing efficiency and extending lifetime, and to substitute steam turbines with electric machinery. All of this was executed on the existing platform to minimize civil works and construction effort.

Successful references showcase the potential of machine electrification in unlocking new business opportunities by drastically improving the carbon footprint of industrial plants.
Looking at a typical electrification project, the booster air compressor (BAC) and the main air compressor (MAC) had reached the end of their lifecycle, and our engineers were tasked with integrating new equipment. Continuity of gas supply was crucial for the downstream customer, which is why the work was split into several, short shutdown windows. Our team installed the new BAC and MAC units, electrical machinery and piping beside the existing ones during live operations, and carried out the actual replacement work during the shutdowns. The entire substation was pre-assembled and tested to plug-and-play level. Careful planning was key, and the construction sequence was precisely planned to ensure the work could be carried out safely while maintaining the tight schedules.
The new BAC, MAC and electrical machines were successfully integrated on both ASU trains during three shutdown windows. Successful project outcomes include maximum leverage of the existing facilities and added operational value thanks to an increase in capacity for high-pressure gaseous oxygen (GOX) and clean dry air (CDA).

Machine Electrification in ASUs
What’s the best electrification strategy for your ASU?
The answer to this question is often more complex than you might think. While adding electrical machinery to an existing plant might seem easy at first glance, there are many factors to consider to ensure an ideal fit and efficient operations.

The deployment options in brownfield environments hinge on the situation on site, including the existing layout, foundations and power grid connection.
Other core factors in the electrification decision-making process include:
- the number of machines deployed
- the type of gears
- whether you use one or more variable frequency drives (VFDs)
These and other factors must be carefully weighed up to reflect your individual ASUs requirements. After all, the best revamp option is always the one that achieves the desired outcome with the lowest effort and cost. Our experts have the experience to help you strike the perfect balance.
