CO2 RECOVERY APPARATUS AND METHOD |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To further reduce the concentration of basic amine compounds remaining in decarbonated exhaust gas. <P>SOLUTION: A CO<SB>2</SB>recovery apparatus includes an absorption tower 2 having a CO<SB>2</SB>absorption portion 21 for absorbing CO<SB>2</SB>in exhaust gas 101 into a basic amine compound absorbing liquid 103 by bringing them into contact with each other and at least one or more washing portions 22 for removing basic amine compounds accompanied by decarbonated exhaust gas 101A, from which CO<SB>2</SB>has been removed in the CO<SB>2</SB>absorption portion 21, by bringing the decarbonated exhaust gas 101A into contact with washing water 104A, 104B, and a regeneration tower 3 for releasing CO<SB>2</SB>from the CO<SB>2</SB>-absorbed basic amine compound absorbing liquid 103, and includes an absorption liquid treatment portion 23 disposed downstream of the flow of the decarbonated exhaust gas 101A of the washing portion 22 for further removing the basic amine compounds accompanied by the decarbonated exhaust gas 101A by bringing the decarbonated exhaust gas 101A into contact with circulating acidic water 105. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
