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 …
desulfurization equipment By: W.H.D. Plant and W.L. Mathay Flue gas desulfurization (FGD) is the removal of the sulfur oxides from gaseous products produced by the combustion of fossil fuels. Conventional combustion technology results in most of the sulfur in the fuel being oxidized and released into the flue gas - which contributes to the ...
