摘要： Provided are: a wet desulfurization apparatus 13 which removes sulfur oxides in flue gas 12A from a boiler 11; a mist collection/agglomeration apparatus 14 which is provided on a downstream side of the desulfurization apparatus 13 and forms agglomerated SO 3 mist by causing particles of SO 3 mist contained in flue gas 12B from the wet desulfurization apparatus 13 to be bonded together and have bloated particle sizes; a CO 2 recovery apparatus 18 constituted by a CO 2 absorption tower 16 having a CO 2 absorption unit 16A which removes CO 2 contained in flue gas 12D by being brought into contact with a CO 2 absorbent and an absorbent regeneration tower 17 which recovers CO 2 by releasing CO 2 from the CO 2 absorbent having absorbed CO 2 and regenerates the CO 2 absorbent; and a mist collection unit 16C which collects CO 2 absorbent bloated mist bloated by the CO 2 absorbent being absorbed by the agglomerated SO 3 mist in the CO 2 absorption unit 16A.

摘要： An SO 3 separating and removing equipment (10) capable of lowering the density of SO 3 contained in flue gas and separating and removing SO 3 component from the flue gas at the inlet of a wet type desulfurization equipment (7) by installing a sodium carbonate feeding device (20) for feeding sodium carbonate to the flue gas at the outlet of a boiler (1), comprising a heat exchanger of shell and tube type, wherein the flue gas is passed through a shell side and boiler feed water is passed through the tube side to cool the flue gas to the dew point of H 2 SO 4 gas or below to react the SO 3 component contained in the flue gas with moisture contained in the flue gas according to the lowering of temperature so as to produce H 2 SO 4 gas which is condensed and adhered onto the surface of tubes, and the liquid H 2 SO 4 adhered onto the surface of the tubes is washed out by using water to remove the SO 3 component from the flue gas, whereby the consumed amount of sodium carbonate can be remarkably reduced, and a plant running cost can be prevented from increasing.
