Wet FGD Chemistry and Performance Factors

Chemical Reaction Steps in FGD Process •SO 2 absorption in absorber •Neutralization of the absorber SO 2 to keep the SO 2 vapor pressure low so that more SO 2 can be absorbed •Dissolution of the limestone or lime reagent to provide alkalinity for neutralization and calcium ion for precipitation •Oxidation of absorbed SO 2 to form sulfate (SO 4)

Wet Flue Gas Desulfurization (FGD) Systems - Gas

For a lime FGD system, a lime slaker processing pebble lime is required in place of the limestone wet ball mill. To facilitate the disposal of the solid waste, or to produce a saleable product in the form of high quality gypsum, a forced oxidation system may be utilized to oxidize the main reaction product, calcium sulfite, to gypsum.
