요약

Systems and processes for treating acid gas from a sour gas stream are provided. A chemical looping combustion (CLC) process is provided that uses CaCO3 to capture sulfur from the acid gas and produce CaSO4. An acid gas treatment unit may receive an acid gas from an acid gas removal unit and produce the CaSO4 and 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 H2S and CO2 permeate that is mixed with the acid gas stream provided to the acid gas treatment unit.

대표청구항

1. A system, comprising: an acid gas treatment unit operable to treat an acid gas stream comprising hydrogen sulfide, the acid gas treatment unit comprising: a fuel reactor operable to receive the acid gas stream and calcium oxide, the fuel reactor further operable to react the hydrogen sulfide with the calcium oxide to produce calcium sulfide and a first gas stream comprising water vapor and carbon dioxide;an oxidizer reactor operable to receive the calcium sulfide and a first air stream, the oxidizer reactor further operable to produce calcium sulfate and an oxygen-lean second air stream, the oxygen-lean air stream comprising no more than 15% by weight oxygen: anda calciner reactor operable to receive the oxygen-lean second air stream and calcium carbonate, the calciner reactor further operable to produce the calcium oxide and a second gas stream, the second gas stream comprising carbon dioxide.
