<P>PROBLEM TO BE SOLVED: To provide a system and a method for recovering carbon dioxide where oxygen dissolved in an absorption liquid is removed and carbon dioxide can be stably recovered. <P>SOLUTION: The system is equipped with an absorption column 100 where carbon dioxide in an exhaust gas 103 is absorbed in the absorption liquid 150 by gas-liquid contact of the exhaust gas 103 with the absorption liquid 150, a regeneration column 110 to regenerate the absorption liquid 150 by releasing carbon dioxide from the absorption liquid 150 in which carbon dioxide is absorbed, absorption liquid lines 130a and 130b which introduce the absorption liquid 150 exhausted from the absorption column 100 to the regeneration column 110, an oxygen removal apparatus 120 existing between the absorption liquid lines 130a and 130b and to remove oxygen dissolved in the absorption liquid 150 and an absorption liquid line 131 to introduce the absorption liquid 150 exhausted from the regeneration column 110 to the absorption column 100. <P>COPYRIGHT: (C)2007,JPO&INPIT |
