PROCESS FOR REMOVING HYDROGEN SULFIDE FROM VERY SOUR HYDROCARBON GAS STREAMS USING METAL SULFIDE

摘要

A process for sweetening a gas stream containing hydrogen sulfide wherein said process comprises contacting said gas stream within a contacting zone a contacting composition comprising metal sulfide in a lower sulfided state and yielding from said contacting zone a product gas stream having a reduced hydrogen sulfide concentration and a recovered contacting composition comprising metal sulfide in a higher sulfided state.
