This reaction is of great interest in the study of wet flue gas desulfurization processes. In the case of the normally used absorption additive lime, the oxidation of S(IV) is an essential step in quantitatively producing the final product, gypsum (CaSO 4 - 2H 2 O). Beside detoxication of S(IV) the dewatering properties of gypsum are improved when a high oxidation yield is achieved.Alstom's experience with limestone/gypsum wet flue gas desulphurisation began with pilot studies in the mid-1960s, followed by the first commercial installations in 1968. Since that time the technology has been applied to over 37,000 megawatt (mw) of electrical generating capacity at over 70 plants. As its name implies, limestone/gypsum wet FGD ...
