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.

15-12-2018· What Does Flue-Gas Desulfurization (FGD) Mean? Flue-gas desulfurization (FGD) is the removal process of sulfur dioxide (SO 2) from flue gas emissions, often chemically.Sulfur dioxide in gases is produced by the combustion of fossil fuels and many industrial processes such as gasoline refining as well as cement, paper, glass, steel, iron and copper production.
Exhaust flue gas is drawn from the boiler and forced into an absorber tower by a booster fan. Once inside the absorber tower, the gas flows upwards through a dense shower of lime or limestone slurry. The slurry absorbs the Sulfur Dioxide (SO2) in the flue gas. The absorption process converts the lime/limestone into Calcium Sulfite.
Flue Gas Desulphurization. Flue gas desulphurization (f.g.d.) has been one of the major growth areas in chemical engineering over the past decade especially in the U.S., Japan and W. Germany. The present trend in the U.S. indicates a doubling of f.g.d. capacity in the next 5-6 years (20, 21).

In a flue gas desulphurisation system (FGD), 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. This can remove up to 95 % of the sulphur dioxide from the flue gas, since the current threshold value for SO 2 in the EU is 200 mg/Nm 3 (Nm 3 = normal cubic metre).
