Process for the recovery of an acid gas from a gaseous stream containing acid gas

U.S. Patent Number: 5387277

Abstract: A process for removing a water-soluble acid gas from a gaseous stream containing normally gaseous hydrocarbon compounds, hydrogen and the acid gas to produce an aqueous solution containing the dissolved acid gas and having a very low level of normally gaseous hydrocarbon compounds. The gaseous feed stream is contacted with a lean aqueous stream to remove water-soluble acid gas. The resulting acid gas rich aqueous stream is stripped with a hydrogen-rich gas to produce an aqueous stream containing dissolved acid gas and essentially no normally gaseous hydrocarbon compounds.
