Abstract In an embodiment, a CO2 recovery system has an absorber, a regenerator, and a circulation device. An absorption liquid has 5 an aqueous solution of amine having an alcohol group, and dimethyl silicone oil in which a part of methyl groups is substituted by at least one type selected from an aminoalkyl group, a carboxyl group, and a hydroxyl-containing alkyl group. The absorber contacts a combustion exhaust gas of a fossil fuel and the absorption 10 liquid to absorb C0 2 , which is contained in the combustion exhaust gas, into the absorption liquid. The regenerator releases CO 2 by applying thermal energy to the C02-absorbed absorption liquid. A circulation device circulates the absorption liquid between the absorber and the regenerator. |
