Flue Gas Desulfurization (FGD) Working | Thermal Power Plant

Introduction. Flue gas desulfurization (FGD) is the removal process of sulfur dioxide (SO2) from flue gases. 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.

SO2 Control

 · In semidry FGD systems, the sorbent is introduced as aqueous slurry, but the water content is controlled so that the slurry dries completely in the flue gas ductwork and the byproducts are dry solids. CDS technology is another type of a dry FGD system. It is primarily useful where the sulphur content in coal is medium to high.
