<p><P>PROBLEM TO BE SOLVED: To provide a CO<SB>2</SB>recovery apparatus and a method with further increased energy efficiency. <P>SOLUTION: This CO<SB>2</SB>recovery apparatus includes an absorbing tower 13 removing CO<SB>2</SB>by bringing CO<SB>2</SB>-containing gas 11 into contact with CO<SB>2</SB>absorbing liquid 12 and a regenerating tower 15 regenerating a rich solution 14 having absorbed CO<SB>2</SB>, and reuses a lean solution 16 from which CO<SB>2</SB>has been removed in the regeneration tower 15, in the absorbing tower 13. The apparatus is also provided with a regenerating heater 18 at the vicinity of the bottom of the regenerating tower 15 for drawing out the recovered lean solution 16 to the outside and heat-exchanging with high temperature steam 17; and a steam condensate heat exchanger 21 provided in a rich solution supply pipe 20 supplying the rich solution 14 from the absorbing tower 13 to the regenerating tower 15, and heating the rich solution 14 with remaining heat of steam condensate 19 from the regenerating heater 18. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
