Flue Gas Desulfurization
The flue gas exiting the absorber is highly corrosive because it's saturated with water and still containing SO 2 These highly corrosive gasses can damage any downstream equipment Using corrosive resistance materials or reheating the gasses above dew point minimize corrosion In dry injection or spray drying systems the SO 2 reacts first with limestone before removing particulates from the flue gas In some cases wet flue gas desulfurization (WFGD) systems installed in coal fired power plants to control SO 2 emissions have been used to decrease mercury emissions [3–7] In such systems SO 2 usually reacts with the limestone slurry to produce insoluble gypsum
