Method for efficiently recovering carbon dioxide in gas |
摘要 |
Disclosed is a method for recovering carbon dioxide from a gas containing carbon dioxide, comprising the step (1) of bringing a gas containing carbon dioxide into contact with an aqueous solution containing 2-isopropylaminoethanol and at least one substance selected from the group consisting of piperazines and alkanolamines to absorb carbon dioxide into the aqueous solution; and the step (2) of heating the aqueous solution containing carbon dioxide absorbed therein, which is obtained in the step (1), to separate and recover carbon dioxide from the solution. |
