Patent ID: 7964168

Claim:
Method of capturing the CO 2 contained in combustion fumes wherein the following steps are carried out in combination: a) burning a fuel, producing combustion fumes; b) contacting cooled combustion fumes obtained in step e) with an absorbent solution in order to produce CO 2 -poor fumes -and a CO 2 -laden solution; c) regenerating the CO 2 -laden solution in a thermal regeneration column in order to produce a regenerated absorbent solution and a CO 2 -rich gaseous effluent; d) cooling the CO 2 -rich gaseous effluent in order to obtain a CO 2 -enriched gaseous fraction which is evacuated, and a liquid fraction e) heating the liquid fraction by heat exchange with the combustion fumes to form a heated liquid fraction and cooled combustion fumes; and f) introducing the heated liquid fraction at a head of the thermal regeneration column as reflux.
