EXHAUST GAS TREATMENT SYSTEM AND METHOD

WIPO Patent Application WO/2011/152550

A1

An exhaust gas treatment system comprising: a desulfuration unit (15) which can remove any sulfur oxide from an exhaust gas (12) discharged from a boiler (11); a cooling column (16) which is arranged on a latter stream side of the desulfuration unit (15), can remove any sulfur oxide that remains in the exhaust gas, and can decrease the temperature of the gas; a CO2 collection unit (17) which comprises an absorption column that can bring CO2 contained in the exhaust gas into contact with a CO2 absorption solution to remove CO2 and a reproduction column that can release CO2 from the CO2 absorption solution to collect CO2 and can reproduce the CO2 absorption solution; and a wet-mode electric dust collection unit (25) which can remove any mist-generating substance, wherein the mist-generating substance is a source of generation of a mist in the absorption column in the CO2 collection unit prior to the introduction of the exhaust gas into the CO2 collection unit.
