Limestone is a common non-metallic mineral and a valuable resource with a wide range of uses. In modern industry, limestone is the main raw material for the manufacture of cement, lime, and calcium carbide. It is an indispensable flux limestone in the metallurgical industry.

The process uses limestone or lime powder to absorb sulfur from flue gas. The sulfur is converted into gypsum in an open spray tower absorber. Gypsum slurry is dewatered into an easily handled by-product that is suitable as raw material, for example, in the wallboard and cement industry.

Lime/limestone-gypsum wet desulphurization technology: after de-dusting flue gas, lime or limestone slurry is used as desulfurizer to absorb S02, and the final product is gypsum. Desulfurization Equipment Performance parameters: Cycling semi-dry method: When the ratio of calcium to sulfur is 1.2~1.3, the desulfurization rate can reach 90%.

The limestone slurry made of limestone powder and water is pumped into the absorption tower to fully contact and mix with the flue gas. The sulfur dioxide in the flue gas, the calcium carbonate in the slurry and the air blown from the lower part of the tower undergo neutralization reaction and oxidation reaction to form calcium sulfate.

Limestone Desulfurization Of Flue Gases Flue Gas Desulfurization Processes. The process of FGD(Flue Gas Desulfurization) is designed to absorb the sulfur dioxide in the flue gas before it is released. This is accomplished through either a wet or a dry process. Dry Lime FGD.
