from the flue gas. Since lime and limestone are not soluble in water, they are used either in the form of an aqueous slurry or in a dry, powdered form. When using an aqueous slurry of sorbent, the FGD system is referred to as a wet scrubber. When using a dry, powdered sorbent, the system is referred to as a dry system.
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.
With increasingly stringent norms for gaseous emissions, FGD technology is emerging as a clear choice with plant operators to reduce emissions. by Ecomak Systems Introduction - What is FGD? Flue Gas Desulphurization or FGD is a set of technologies used to remove SO2 from exhaust flue gases of fossil-fuel power plants, and from the …

Neither lime nor limestone dissolves well in water and therefore, both are pumped in slurry form to the scrubber tower. Lime slurry is more alkaline, having a pH of 12.5 while limestone slurry is roughly neutral. A lime based system will therefore add more lime when pH drops below 12 and a limestone based system will be controlled around 6. Unless
