<p><P>PROBLEM TO BE SOLVED: To provide a separation and collection method of CO<SB>2</SB>in the atmosphere. <P>SOLUTION: This CO<SB>2</SB>separation and collection method comprises processes for: separating a CO<SB>2</SB>-containing absorbent aqueous solution from other gas-containing aqueous solution, by supplying CO<SB>2</SB>-containing gas and CO<SB>2</SB>absorbent aqueous solution to the hollow fiber membrane module, comprising the hollow fiber membrane containing a bundle of the separation membrane for CO<SB>2</SB>collection with permeation performance increasing from one end toward the other end; and separating and collecting CO<SB>2</SB>from the CO<SB>2</SB>-containing absorbent aqueous solution obtained in the previous process. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
