FLUE GAS DESULPHURIZATION
from flue gas 9 (see Figure 1: Schematics of a wet FGD system).10 Flue gas is sprayed with a reagent (wet limestone is commonly used), which reacts with the SO 2 in the flue gas producing calcium sulphate di-hydrate [CaSO 4 •2H 2 O], also known as gypsum. The process limits the amount of SO 2 that can escape into the atmosphere.

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.
