<p><P>PROBLEM TO BE SOLVED: To provide an immersion type CO<SB>2</SB>separation apparatus having excellent efficiency of CO<SB>2</SB>separation and recovery. <P>SOLUTION: Gas including CO<SB>2</SB>is introduced from a gas introduction line 33, and the gas is urged to be dispersed and dissolved into a CO<SB>2</SB>absorber aqueous solution in a separation tank 11, by the action of a diffuser 31 and a perforated plate 32. Thereafter, by the use of an external pressure type hollow fiber membrane apparatus 21, the CO<SB>2</SB>absorber aqueous solution in which the CO<SB>2</SB>-containing gas is dispersed and dissolved is separated into CO<SB>2</SB>-containing CO<SB>2</SB>absorber aqueous solution and other gas-containing aqueous solution and then CO<SB>2</SB>is recovered. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
