SOUR GAS COMBUSTION USING IN-SITU OXYGEN PRODUCTION AND CHEMICAL LOOPING COMBUSTION

A chemical looping combustion (CLC) process for sour gas combustion includes a number of reaction zones and is configured to provide in-situ oxygen production and in-situ removal of SO2 from a product gas stream by reacting the SO2 with a calcium-based sorbent at a location within one reaction zone....

More Information
Summary:A chemical looping combustion (CLC) process for sour gas combustion includes a number of reaction zones and is configured to provide in-situ oxygen production and in-situ removal of SO2 from a product gas stream by reacting the SO2 with a calcium-based sorbent at a location within one reaction zone. The CLC process is also configured such that the in-situ oxygen production results from the use of a metal oxide oxygen carrier which is purposely located such that it does not directly contact the sour gas, thereby eliminating the generation of undesirable sulfur-based metal oxides.
