FLUE GAS DESULFURIZATION (SCRUBBING) In a flue gas desulfurization (FGD) system, sulphur compounds are removed from the exhaust emissions of fossil-fuelled power stations. This is done by means of an industrial process through the addition of absorbents. Flue gas desulfurization can remove up to 95 % of the sulphur dioxide from the flue gas.
