FLUE GAS DESULFURIZATION

What is Flue Gas Desulfurization (FGD)? FGD is a set of technologies used to remove Sulfur Dioxide (SO2) from exhaust flue gases in coal, oil-fired, and waste- to-energy power stations. SO2 is a pollutant/irritant in air and a major contributor in the creation of acid rain. SO2 emissions are subject to strict environmental protection regulations.

Processes of Flue Gas Desulfurization (FGD) Technology: Limestone Scrubbing. Limestone slurry is sprayed on the incoming flue gas. The sulphur dioxide gets absorbed. The limestone and sulfur dioxide react as follows : CaCO 3 + H 2 O + 2SO 2----> Ca +2 + 2HSO 3-+ CO 2 CaCO 3 + 2HSO 3-+ Ca +2----> 2CaSO 3 + CO 2 + H 2 O

Abstract. The wet-flue-gas desulfurization (FGD) process plays an important role in removing water-soluble flue-gas components such as sulphur dioxide (SO 2) and oxidized mercury compounds.Under the reducing environment of the FGD, there is the possibility of re-emission of the already absorbed mercury (Hg) to the gas phase, which may be diminished by the utilization of specific additives.
