The present invention relates to a method for capturing CO 2 from exhaust gas in an absorber (A 1 ), wherein the CO 2 containing gas is passed through an aqueous absorbent slurry wherein said aqueous absorbent slurry comprises an inorganic alkali carbonate, bicarbonate and at least one of an absorption promoter and a catalyst, and wherein the CO 2 is converted to solids by precipitation in the absorber, said slurry having the precipitated solids is conveyed to a separating device (F 1 ), in which the solids are separated off, essentially all of at least one of the absorption promoter and catalyst is recycled together with the remaining aqueous phase to the absorber. |
