Summary

A waste-heat-powered ammonia absorption refrigeration unit (ARU) has been installed at the Commerce City refinery of Ultramar Diamond Shamrock. The ARU provides 300 kW of refrigeration at -43 °C to refrigerate and to treat gas from a reformer plant, thereby recovering 7950 m3 per year of liquefied petroleum gas (LPG) which was formerly flared or burned as fuel. The refinery's investment has already been paid back in the first two years of operation. As an additional benefit CO2 emissions in the Denver area have decreased by 10,000 tons per year.
