Abstract
A feed gas comprising CO, HS and His treated to produce an H-enriched product and an HS-lean, COproduct. The feed gas is separated to provide the H-enriched product and a stream of sour gas. The stream of sour gas is divided into two parts, one of which is processed in an HS removal system to form one or more streams of sweetened gas, and the other of which bypasses the HS removal system, the stream(s) of sweetened gas and the sour gas bypassing the HS removal system then being recombined to form the HS-lean, COproduct gas. The division of the sour gas between being sent to and bypassing the HS removal system is adjusted responsive to changes in the HS content of the sour gas, so as to dampen or cancel the effects of said changes on the HS content of the HS-lean, COproduct gas.
