Summary:222 22 22 22 222 2x2 32A feed gas comprising CO, HS and His treated to produce an H-enriched product and a COproduct. The feed gas is separated by pressure swing adsorption to provide a stream of the H-enriched product, and two streams of sour gas depleted in Hand enriched in HS and COrelative to the feed gas. One of the streams of sour gas is processed in an HS to elemental sulfur conversion system, in which HS in the sour gas is converted to elemental sulfur order to obtain a stream of sweetened gas, from which the COproduct is formed. The other of said streams of sour gas is processed in an oxidation system, in which HS in the sour gas is oxidized to SO(SOand SO) which is introduced into the HS to elemental sulfur conversion system.
