Low Pressure Olefins Recovery is a cost-effective route to recovery ethylene, ethane and other hydrocarbons from FCC, coker and other refinery gas streams.  

LPR/ C2+ OCT to Propylene

Various refinery processing schemes such as FCC, coker, high olefin FCC and DCC produce C3 and lighter components that often are rejected to the refinery fuel gas system. CB&I’s Low Pressure Recovery (LPR) technology is a highly-efficient, low-cost and inherently safe process for the recovery of ethylene, propylene, ethane and propane from these and other refinery off gas streams.
