Abstract (en)
[origin: WO2013067648A1] The method for CO2 capture includes operating a CO2 capture system with a large temperature swing in between the absorption stage and the desorption stage; utilizing a hybrid solvent comprising water, carbonic anhydrase and an absorption compound in the absorption stage; membrane filtering the carbonic anhydrase out of the hybrid solvent in between the absorption stage and the desorption stage and prior to the large temperature swing; and recycling the filtered carbonic anhydrase back into the absorption stage to maintain high enzyme concentration in the absorption stage.
