<p><P>PROBLEM TO BE SOLVED: To provide a carbon dioxide-collecting method and device which detect with time, the concentration of carbon dioxide in an absorbent, exert a stable carbon dioxide collection performance, enable response to conditional fluctuation or the like, and have high applicability. <P>SOLUTION: Carbon dioxide is absorbed in an absorbent by bringing a carbon dioxide-containing gas G into contact with the absorbent in an absorption tower 10, and the absorbent is regenerated by heating at a regeneration tower 20 to make carbon dioxide release. The absorbing agent concentration in the absorbent is decided by detecting the total organic carbon amount of the absorbent using a total organic carbon analyzer 40, and a control part 43 controls the absorbing agent concentration of the absorbent on the basis of the above decision. Besides, the control part controls the carbon dioxide-collection performance of the absorbent as a circulation system by adjusting a circulation velocity and heating degree. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
