The most common cement setting retarder used in industry is natural gypsum, which is primarily a dihydrated product of calcium sulfate (CaSO 4 · 2H 2 O). The need for gypsum in cement increases with increasing amount of C 3 A and alkalies in the clinker and the fineness of the cement [1], [2], [3]. Gypsum also promotes cement …

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 emissions of other sulphur oxide-emitting processes. Sulphur dioxide is released in the combustion of coal, gas and oil. In this system, equipment such as absorber towers, demister supports, gas …

The FGD process is designed to capture and remove SO2 from flue gases produced during the combustion of fossil fuels. The FGD process involves various methods, with wet scrubbers and dry scrubbers being the two primary approaches. Wet scrubbers utilize a liquid sorbent, typically limestone slurry, to react with the SO2 in the flue gas, …
