Abstract: A method for stripping CO2 from a biocatalyst-containing CO2-rich absorption solution to produce a biocatalyst-containing CO2-lean absorption solution and a CO2-rich gas is provided. The method includes generating a stripping gas from a portion of the biocatalyst-containing CO2-lean absorption solution in a stripping gas generation unit, and contacting the biocatalyst-containing CO2-rich absorption solution with the stripping gas in a gas-liquid contactor to produce the CO2-lean absorption solution and the CO2-rich gas.
