Abstract
Planetec Utility Services Co. Inc. and Energy Concepts Co., in cooperation with the US Department of Energy developed and commissioned a unique waste-heat powered ammonia absorption refrigeration (AAR) plant for LPG recovery at the Denver refinery operated by Ultramar Diamond Shamrock. The environmentally-friendly technology reduces flare emissions and the loss of salable liquid-petroleum products to the fuel-gas system. AAR is applied to the refinery's fuel-gas makeup streams to condense over 180 b/d of salable liquid hydrocarbon products, increasing annual profits by nearly $1 million, while substantially reducing air polluting emissions from the refinery's flare.
