摘要： An object of the present invention is to solve these problems and to provide a exhaust gas treatment system which prevents formation of deposits in a main duct and a flue, on and after the point where the exhaust gases converge, after the removal of CO2 and reduces labor required for maintenance such as cleaning, and thus enabling a long-term operation. Disclosed is an exhaust gas treatment system equipped with a carbon dioxide removal device, comprising a main duct 6 through which an exhaust gas, after treating an exhaust gas from a boiler 1 by a wet desulfurization device, passes; a diverging duct 40 configured to diverge some of an exhaust gas flow from the main duct; an CO2 removal device 20 configured to absorb and remove carbon dioxide (CO2) in the diverged exhaust gas by an amine absorbent; and a return duct 42 configured to converge the exhaust gas, from which CO2 has been removed by the CO2 removal device, with an exhaust gas that has not yet been diverged, wherein the return duct 42, before the point where the exhaust gases converge, is provided with heating means 8 configured to vaporize mist of the amine absorbent in the exhaust gas after convergence.
