Dry Air Supply for Restart

Case study

Dry air supply for restart

Client:KemOne

Location:Fos-sur-Mer, France

Sectors:Petrochemical and refining

The challenge

Urgent restart with zero moisture tolerance

Following a scheduled technical shutdown, KemOne faced the critical task of restarting its production units without any trace of residual moisture. To achieve this, they required a rapid deployment of a dry, oil-free compressed air system compliant with Class 0 standards—an essential step to ensure the safe and efficient drying of their units. The situation presented two major challenges: first, the urgency of the request, which came in at the last minute and left only three days for response and mobilization; and second, the complexity of the setup, which demanded precise system dimensioning and installation across multiple injection points, all while adapting to a constantly shifting project schedule. Without a timely and effective solution, the customer risked prolonged downtime.

The solution

Tailored engineering and rapid deployment

Aggreko responded with a bespoke, high-performance compressed air system that was designed and deployed in record time to meet KemOne’s urgent needs. Drawing on previous operational feedback from the client, the system was precisely dimensioned to ensure optimal performance. All deployed equipment was Stage V compliant, minimizing emissions and maximizing fuel efficiency—an important factor in both environmental and operational terms.
Each compressor line was fully integrated with pressure regulation, drying, and safety components to meet the exact technical specifications required for the drying process. To ensure seamless execution, Aggreko remained fully mobilized on-site throughout the project, providing continuous maintenance and adapting to the client’s evolving schedule. This level of responsiveness and technical precision was a key reason KemOne selected Aggreko for the project, trusting in our ability to deliver under pressure with a commercially competitive and environmentally responsible solution.
 

The impact

Reliable execution and tangible results

Aggreko’s rapid response and technical precision enabled KemOne to restart operations on time with fully dried units, avoiding costly delays and maintaining production continuity. The client expressed high satisfaction with the outcome, particularly appreciating Aggreko’s responsiveness, technical expertise, and the quality of service delivered under pressure.
Beyond the immediate technical success, the project highlighted Aggreko’s added value: a proactive mindset, a commitment to seeing the project through, and the flexibility to adapt to evolving on-site demands. These qualities, combined with a commercially competitive offer and a proven track record, gave Aggreko a clear edge over the competition and reinforced the client’s trust in our ability to deliver under critical conditions.
