IMPROVED CO2 ABSORPTION METHOD

摘要

A method for removing CO2 in a exhaust gas from combustion of carbonaceous material, in which method the exhaust gas is brought in countercurrent flow with a liquid CO2 absorbent in a contact section of an absorption column, to produce a CO2 depleted exhaust gas that is released into the atmosphere and a CO2 rich absorbent that is withdrawn from the absorption column, wherein the exhaust gas is introduced into the absorption column at a temperature above about 90 and the exhaust gas is cooled in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.
