Case Study: Aggreko Helps Refinery Maintain Production During Shutdown

Aggreko Helps a Major Refinery Maintain Production During Seasonal Shutdown

The Customer Challenge

A major refinery needed a way to maintain desired production rates during a seasonal shutdown of its fluidized catalytic cracking unit (FCC) for inspections and repairs. The shutdown would require the plant to reduce the charge rate to the crude unit supplying the FCC’s heavy gas oil (HGO) feed, threatening the plant’s productivity.

The Aggreko Solution

Aggreko Process Services (APS) engineers met with refinery officials and subsequently identified a need for approximately 30% more cooling. APS proposed a fully integrated design, engineering and installation solution designed to address the specific needs of the facility.

Aggreko’s solution managed the safety and environmental risk associated with the excessive HGO feed and allowed the refinery to maintain operation despite the shutdown.

The Benefit to the Customer

The refinery’s Lead Design Engineer commented, “We operated the system for the first time at 30,000 BPD process flow rate and achieved an outlet temperature of 180ºF, which is consistent with the process design. I am particularly impressed with the quality of the installation and the dedication of Aggreko’s field service personnel. Because of the quick, competent response by Aggreko, we will be able to capture a profit opportunity that far outweighs the project cost.”
