Larson, H A; Boehme, M F; Sheets, J W

An integrated process for removal of hydrogen sulfide and water from a natural gas stream by contacting a natural gas stream containing hydrogen sulfide, water, and CO/sub 2/ with molecular sieves that act both as an adsorbent for hydrogen sulfide and water and as a catalyst for the reaction for conversion of hydrogen sulfide and carbon dioxide to carbonyl sulfide. About 92 to about 95 volume percent of an inlet natural gas stream is passed into contact with molecular sieves to produce a salable gas. A portion of this salable gas is used as regeneration fluid for the molecular sieve contactors and the regeneration gas effluent from the regeneration process is diluted with the remainder of the inlet gas stream and subjected to further adsorption/conversion contact with molecular sieves to produce salable gas that is mixed with the first treated gas stream. Depending upon the degree of compression of the regeneration gas effluent from the regenration operation, the integrated system can be operated with two phases of adsorption or with a single phase of adsorption of mixed streams of inlet gas and regeneration gas.
