Flue Gas Desulfurization (FGD)

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.

An experimental study on the ultra-fine grinding of gypsum …

 — Gypsum is a crystalline form of hydrated calcium sulfate (CaSO 4 ·2H 2 0) generally used in cements and plasters in the construction industry, though also in paints, fertilizers, medicines, papers, and textiles. For use in these materials, gypsum must be ground finely (< 100 μm), if not ultra-finely (< 10 μm), for which ball mills are most effective.
