Coker Maintenance Without Downtime

Eliminate production loss during maintenance windows

What happens in your refinery when you have a Turnaround lined up? Specifically, when you need to shut down your Coking Unit for planned maintenance?

Turnarounds should not mean closure and financial loss, Coker Unit maintenance is no exception. With Aggreko Process Services (APS) expertise and foresight, we keep your refinery fully operational during maintenance programmes.

The modern refiner can take advantage of our smarter approach to Turnarounds which include new ways of replicating heat integration and ‘splitting’ units from those which need maintenance. This technique of taking units offline independently means APS can install proven solutions, backed by a highly successful track record which avoids any uncertainty when it comes to Coker maintenance.

By empowering acute approaches to Turnarounds, practices such as ‘decoupling’ only affect the unit needing maintenance. By externally storing feed material for this unit during the period of downtime, it can then be added back into the unit post maintenance and can be reheated and reprocessed.

Traditionally downtime would be expected as there would have been no buffer between Coking Unit and Vacuum Towers, meaning excessive temperatures and a shutdown in production. Aggreko has successfully developed solutions and commercially demonstrated projects that allow refiners to de-couple units and to maintain production with critical units.

Frequently asked questions

Engineer and blur refinery oil background.

By decoupling the coking unit from interconnected process units, maintenance can be isolated to the coker, while operations continue running. Temporary process solutions maintain heat balance and material flow so overall refinery throughput is preserved.

Feed streams are temporarily redirected or buffered, and external system replicate key heat-integration functions. This allows units such as the vacuum tower to remain stable without exposing equipment to excessive temperatures or forcing a shutdown.

Temporary, modular process systems provide the flexibility to manage flow, temperature, and storage during maintenance windows. These solutions are engineered to integrate into live operations, reduce risk during turnarounds, and avoid production losses associated with full unit outages.
