The acid gas, primarily hydrogen sulfide (H2S) and carbon dioxide (CO2), that is separated from the feed gas is typically processed in one of several ways to prevent its release into the atmosphere and to potentially recover valuable resources. One common method is to send the acid gas to a sulfur recovery unit (SRU), typically a Claus process unit. In the Claus process, H2S is converted into elemental sulfur through a series of chemical re....
