摘要： A process for removing CO.sub.2 from a combustion gas which comprises removing CO.sub.2 from the combustion gas through contact of an aqueous hindered amine solution used as a CO.sub.2 absorbent solution with the combustion gas at atmospheric pressure and then, in a regeneration column, liberating CO.sub.2 from the absorbent solution that has absorbed CO.sub.2 by heating it and thereby regenerating the absorbent solution. The process further comprises a partial absorbent solution regeneration step in at least one stage wherein the absorbent solution that has absorbed CO.sub.2 is heated through heat exchange with a high-temperature regenerated absorbent solution and part of the CO.sub.2 that is liberated is separated from the absorbent solution. Following this, according to the necessity, part of the partially regenerated absorbent solution thus obtained is returned to the step of removing CO.sub.2 from the combustion gas for use as part of the CO.sub.2 absorbent solution while the rest or all of the absorbent solution is heated and fed to a regeneration column further to liberate CO.sub.2 and regenerate the absorbent solution.

摘要： A process for removing carbon dioxide (CO.sub.2) from a combustion exhaust gas of a boiler (1) which generates steam for driving high (3), intermediate (7), and low (8) pressure turbines. The process comprises the steps of removing CO.sub.2 in the combustion exhaust gas by absorption with a CO.sub.2 -absorbing liquid (19), liquefying the removed CO.sub.2 (28) by compression (42) and cooling (48), storing (52) the CO.sub.2, and regenerating the CO.sub.2 -absorbing liquid by a CO.sub.2 -absorbing liquid regeneration column (24) equipped with a reboiler (30). In the process, a part (40) of steam discharged from the high pressure turbine (3) is used to drive turbines (41, 43) for compressors (42, 44) that compress the CO.sub.2, and a refrigerant for cooling the CO.sub.2, and steam (45) discharged from the compressor turbines is supplied as a heating source to the reboiler (30) for the regeneration of the CO.sub.2 -absorbing liquid. A decrease in the overall power plant efficiency due to the removal of carbon dioxide from the exhaust gas can be reduced.
