Abstract
Systems and processes for treating acid gas from a sour gas stream are provided. A chemical looping combustion (CLC) process is provided that uses CaCOto capture sulfur from the acid gas and produce CaSO. An acid gas treatment unit may receive an acid gas from an acid gas removal unit and produce the CaSOand various gas and air streams for use in heat exchangers for steam production. The acid gas treatment unit may include a fuel reactor, an oxidizer reactor, and a calciner reactor. Another acid gas treatment unit may include a fuel reactor that includes the calciner function and an oxidizer reactor. A selective membrane module may be disposed between the sour gas stream and an acid gas removal unit to produce a HS and COpermeate that is mixed with the acid gas stream provided to the acid gas treatment unit.
