Methanol injection and recovery in a large turboexpander plant. [Canada]
Methanol is used to prevent hydrate formation in Petro-Canada's 2000 MMSCFD Empress expander plant. Injection and recovery facilities have operated essentially trouble-free since start-up late in 1979. A portion of the methanol recovery section has been modified to provide removal of the H/sub 2/S and most of the COS from the propane product stream, concurrent with methanol recovery. The Empress straddle plant strips natural gas liquids from pipeline gas leaving Alberta for eastern Canadian and U.S. markets. The original cold oil absorption plant, started up in 1964 and expanded in 1967, recovered over 90% of the propane and virtually all of the heavier components. In 1976, a market for ethane was secured as feedstock for the world-scale ethylene complex under construction in Alberta, and it was decided to replace the cold oil plant with a turboexpander facility. The plant and its operations are described in some detail. 2 refs.
