CO2 RECOVERY SYSTEM AND CO2 RECOVERY METHOD |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To further reduce the concentrations of basic amine compounds remaining in decarbonated exhaust gas. <P>SOLUTION: In a CO<SB>2</SB>recovery system which includes an absorber 2 having a CO<SB>2</SB>absorbing portion 21 for bringing exhaust gas 101 into contact with a basic amine compound-absorbing liquid 103 to absorb CO<SB>2</SB>in the exhaust gas into the basic amine compound-absorbing liquid 103 and a water washing portion 22 for bringing the decarbonated exhaust gas 101A, from which CO<SB>2</SB>has been removed in the CO<SB>2</SB>absorbing portion 21, into contact with circulating washing water 104 to wash and remove the basic amine compounds entrained in the decarbonated exhaust gas, and a regenerator 3 for releasing CO<SB>2</SB>from the CO<SB>2</SB>-absorbed basic amine compound-absorbing liquid 103, a concentrating portion 24 is provided which concentrates the washing water 104 of the water washing portion 22 and returns condensed water generated during the concentration to the water washing portion 22. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
