EXHAUST GAS TREATMENT SYSTEM AND METHOD

摘要

SO x removal equipment (15) which reduces sulfur oxides from flue gas (12) from a boiler (11), a cooler (16) which is provided on a downstream side of the SO x removal equipment (15) so as to reduce the sulfur oxides that remain in the flue gas and decrease a gas temperature, CO 2 recovery equipment (17) which includes an absorber for bringing CO 2 in the flue gas into contact with a CO 2 absorption liquid so as to be reduced, and a regenerator for causing the CO 2 absorption liquid to emit CO 2 so as to recover CO 2 and regenerate the CO 2 absorption liquid, a heat exchanger (33) which is provided on an inlet passage side of the electric dust collector to decrease a temperature of the flue gas are included, and a mist generation material in the flue gas is converted from a gas state to a mist state to cause particulates in the flue gas (12) to arrest and reduce the mist generation material in the mist state.
