<p><P>PROBLEM TO BE SOLVED: To provide a carbon dioxide recovering system quickly measuring a carbon dioxide content in a circulated absorption liquid. <P>SOLUTION: The carbon dioxide recovering system 1 includes: an absorption tower 3 in which carbon dioxide is absorbed by an absorption liquid; a regeneration tower 5 in which carbon dioxide is released from the absorption liquid to regenerate the absorption liquid; a regenerating heat exchanger 7 disposed between the absorption tower 3 and the regeneration tower 5 and heating the absorption liquid absorbing the carbon dioxide by using the regenerated absorption liquid as a heat source; a measuring device 20, which partially samples the absorption liquid circulating in the system 1, blowing a mixture gas of carbon dioxide and nitrogen to the sampled absorption liquid, and measuring the concentration of carbon dioxide in the mixture gas in contact with the absorption liquid; a memory unit 40 storing the correspondence relation between the carbon dioxide content in the absorption liquid and the concentration of carbon dioxide in the mixture gas; and a computation control unit 30 which acquires the concentration of carbon dioxide measured by the measuring device 20, referring to the correspondence relation stored in the memory unit 40 and quickly detecting the carbon dioxide content in the sampled absorption liquid. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
