A method for reclaiming CO2 absorbing chemical(s) from a lean aqueous CO2 absorbent leaving a regeneration column (), where lean absorbent () is withdrawn and flashed () to generate a vapor that is compressed () and returned into the regeneration column as stripper gas (), where a part of the lean absorbent () is withdrawn and introduced into a reclaimer () in which the lean absorbent is boiled to generate a gas phase () that is withdrawn and returned into the regeneration column as reclaimed absorbent, and a liquid phase containing impurities (), wherein the gaseous phase that is withdrawn from the reclaimer is compressed () together with the vapor part () from the flashing of the lean absorbent, to generate a pressure in the reclaimer that is lower than the pressure in the regeneration column, and a reboiler () for carrying out the method, are described.

[object Object]

A method for removing COin a exhaust gas from combustion of carbonaceous material, in which method the exhaust gas is brought in countercurrent flow with a liquid COabsorbent in a contact section of an absorption column, to produce a COdepleted exhaust gas that is released into the atmosphere and a COrich absorbent that is withdrawn from the absorption column, wherein the exhaust gas is introduced into the absorption column at a temperature above about 90 and the exhaust gas is cooled in the absorption column by countercurrent flow of the liquid absorbent in the absorption column, is described.
