Flue Gas Desulphurisation (FED): Removal of Sulfur Dioxide is called as Flue-gas Desulphurization (FGD). It seeks to remove gaseous pollutants viz. SO 2 from exhaust flue gases generated in furnaces, boilers, and other industrial processes due to thermal processing, treatment, and combustion. FGD systems may involve wet scrubbing or dry scrubbing.
