CRG-hydrogasification process for SNG production
ALLEN J. WEISS · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 1973
The first plant to produce commercial SNG, interchangeable with natural gas, went on-stream in Portsmouth, England using the CRG-Hydrogasification process with one stage of methanation. The plant has operated with light and heavy naphtha as the feedstock, and the CRG catalyst in the hydrogasifier was successfully regenerated. The process is an improvement over the CRG process with two stages of methanation because of the higher thermal efficiency achieved by lower steam: feedstock ratios. Regeneration of the CRG catalyst offers the potential for further cost reduction in the production of SNG. The production of SNG from petroleum liquids will become a reality in the USA in 1973. The cost of the gas produced by these plants will be higher than the natural gas sold during the past three decades. (MCW)
