Document Type and Number:
WIPO Patent Application WO/2014/136599
Kind Code:

Abstract:
This CO2 recovery system is provided with an absorption device which brings a CO2-absorbing liquid into contact with exhaust gas treated in a pretreatment device and allows the CO2-absorbing liquid to absorb CO2 in the exhaust gas, a regeneration device which separates the CO2 from the CO2-absorbing liquid, an absorbing liquid circulation path which circulates the CO2-absorbing liquid between the absorption device and the regeneration device, and an impurity removal mechanism which, in the absorbing liquid circulation path and/or in advance in the pretreatment device, removes impurities that have a high concentration in the absorbing liquid circulation path.
