Patent ID: 8828130

Claim:
An exhaust gas treatment system comprising: a main duct through which an exhaust gas passes from a boiler, in which the exhaust gas has been treated by a wet desulfurization device; a diverging duct configured to diverge some of an exhaust gas flow from the main duct; a CO 2 removal device configured to absorb and remove carbon dioxide (CO 2 ) in the diverged exhaust gas by an amine absorbent; and a return duct configured to converge the CO 2 -removed exhaust gas in the CO 2 removal device with the exhaust gas that has not yet been diverged in the main duct, wherein the return duct, before the point where the exhaust gases converge, is provided with heating means for vaporizing mist of the amine absorbent entrained in the CO 2 -removed exhaust gas after the convergence.
