The Challenge
Restoring fuel rates during equipment outage
Jet fuel and ultra-low-sulfur diesel (ULSD) are produced in a refinery hydrocracker. ULSD and jet fuel are experiencing peak demand because of current market shortages and the effects of the pandemic. Failure to offset any disruption in production would impact revenues dramatically – at a time when demand has never been higher. Aggreko responded rapidly to the challenge when a condenser on a hydrocracker fractionator was taken out of service for maintenance. The refinery was facing a costly decision of downgrading jet fuel and ULSD.

The Solution
Rapid delivery and install of heat exchanger and cooling tower
The refinery initially believed a production loss was inevitable, since cooling water volume was not only limited, but summertime temperatures of the cooling water would significantly hinder performance. Clearly, a temporary exchanger would also require supplemental cooling via a chiller or cooling tower. However, this additional equipment would require timely process safety reviews during the Management of Change (MOC) and Pre-Startup Safety Review (PSSR) processes. Aggreko enjoys an ongoing partnership and developed a comprehensive engineered solution. We installed a customized, package in 11 days and participated in the MOC and PSSR. The final package consisted of a heat exchanger, pumps, piping, and a cooling tower that was rated for a Class 1, Div. 2, Group C&D electrically classified area.
