flue gas desulphurization

Flue-Gas Desulphurization - an overview

Chellappa Chandrasekaran, in Anticorrosive Rubber Lining, 2017. Sulfur Dioxide Corrosion and Atmospheric Pollution. To minimize the adverse effects of sulfur oxides (SO 2 and SO 3) on the environment, many power plants and industrial facilities use flue-gas desulphurization (FGD) scrubbers to remove SO 2 and SO 3 from combustion gases. The conditions within a scrubber and accompanying ...

Flue Gas Desulfurization - an overview ScienceDirect

This reaction is of great interest in the study of wet flue gas desulfurization processes. In the case of the normally used absorption additive lime, the oxidation of S(IV) is an essential step in quantitatively producing the final product, gypsum (CaSO 4 - 2H 2 O). Beside detoxication of S(IV) the dewatering properties of gypsum are improved when a high oxidation yield is achieved.
