The present invention relates to a method for capturing CO2 from exhaust gas in an absorber (A1), wherein the CO2 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 CO2 is converted to solids by precipitation in the absorber, said slurry having the precipitated solids is conveyed to a separating device (F1), 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. |
