Patent ID: 7541011

Claim:
A method for separating a gas from a gas mixture, the method comprising: introducing a liquid absorbent into an absorber; said liquid absorbent comprising at least one activated agent and at least one solvent, wherein the at least one activated agent reacts or combines with an absorbed gas, and the at least one solvent does not react with the absorbed gas; introducing the gas mixture into the absorber, allowing the liquid absorbent to absorb the gas and to convert the gas into the absorbed gas; allowing the absorbed gas to react or combine with the at least one activated agent in the liquid absorbent to form at least one new compound, wherein said at least one new compound is separated out from the liquid absorbent and forms a gas rich phase; separating the gas rich phase from the rest of the liquid absorbent; cycling the at least one solvent in the rest of the liquid absorbent back to the absorber; regenerating the gas rich phase to obtain the gas and the at least one activated agent; cycling the at least one activated agent obtained from the regenerating step back the absorber.
