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 In the process of dry scrubbing injection systems, lime is used as a reagent to react and remove gaseous pollutants.
ABSTRACT Wet flue gas desulfurization (WFGD), using limestone with forced oxidation (LSFO), is a common Flue gas desulfurization (FGD) process where limestone reacts with SO2 to produce gypsum (CaSO4.2H2O). In South Africa, Eskom's Kusile Power Station utilizes conventional wet ball milling to grind high-grade limestone (96% CaCO3) to 95% passing 45 …
