Title:

CO2 RECOVERY SYSTEM AND CO2 RECOVERY METHOD

Document Type and Number:

WIPO Patent Application WO/2014/136599

Kind Code:

A1

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.
