Abstract
A COrecovery apparatus capable of recovering COby using only a low-quality exhaust heat at 100° C. or less is provided. The present invention includes an absorption tower for allowing a basic aqueous solution to absorb CO; and a regenerator for heating a basic aqueous solution with COabsorbed therein using a heating medium having a temperature of 100° C. or less, thereby desorbing CO.
