<p><P>PROBLEM TO BE SOLVED: To provide a carbon dioxide recovery system capable of improving a system efficiency by regenerating an absorption liquid by utilizing steam led out from a steam turbine as a carrier gas for carbon dioxide radiated from the absorption liquid, and a carbon dioxide recovery method. <P>SOLUTION: The carbon dioxide recovery system comprises: the steam turbine 170; an absorption tower 100 making an exhaust gas 103 into gas/liquid contact with a lean absorption liquid 151; a regeneration tower 110 making a rich absorption liquid 152 absorbed with carbon dioxide into gas gas/liquid contact with steam 120 extracted from the steam turbine 170 to radiate carbon dioxide and regenerate the lean absorption liquid 151; a rich absorption liquid line 130 for leading the rich absorption liquid 152 to the regeneration tower 110 from the absorption tower 100; a lean absorption liquid line 131 for leading the lean absorption liquid 151 to the absorption tower 100 from the regeneration tower 110; and a steam supply line 171 for leading the steam 120 to the regeneration tower 110 from the steam turbine 170. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
