FGD and limestone storage tank

FGD and Limestone

By definition: Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO2) from the exhaust flue gases in power plants that burn coal or oil to produce steam for the steam turbines that drive their electricity generators. Capture of SO2 is accomplished by devices known as scrubbers. The devices combine the sulphur compounds with a calcium containing sorbent, generally lime (CaO) or limestone (CaCO3), to create a slurry. The slurry can be safely discharged after treatment or turned into useful byproducts.
