Abstract
The invention concerns a method for treating a hydrocarbon feed gas stream containing at least COand HS to recover a high quality purified COgas stream, comprising a. Separating said hydrocarbon feed gas stream into a sweetened hydrocarbon gas stream, and an acid gas stream; b. Introducing said gas stream into a Claus unit, c. Introducing the tail gas into a hydrogenation reactor and then into a quench contactor of the Tail Gas Treatment Unit (TGTU); d. Contacting said tail gas stream with a non-selective amine-based solvent into a non-selective acid gas absorption unit of the TGTU; e. Sending the off gas to an incinerator; f. Contacting said enriched gas stream (vii) with a selective HS-absorption solvent into a selective HS-absorption unit thereby recovering a highly purified COgas stream and a HS-enriched gas stream, as well as the device for carrying said method.
