Patent ID: 8318116

Claim:
A method for deacidizing a gaseous mixture comprising an acid gas, the process comprising: contacting the gaseous mixture with an absorbent in an absorption unit, wherein the absorbent comprises a carrier phase and a transportation phase that is immiscible with or mechanically separable from the carrier phase; allowing the transportation phase to absorb the acid gas and convert the acid gas into an absorbed acid gas, so as to convert the absorbent into a gas-rich absorbent and to convert the gaseous mixture into a purified gaseous mixture; allowing the absorbed acid gas to be transferred into the carrier phase, so as to form a first gas-lean phase and a gas-rich phase in the gas-rich absorbent; providing the gas-rich absorbent to a separation unit, so as to separate the first gas-lean phase from the gas-rich phase; cycling the separated first gas-lean phase back into the absorption unit; providing the separated gas-rich phase to a regeneration unit, so as to obtain the acid gas and a second gas-lean phase; and cycling the second gas-lean phase back into the absorption unit.
