Prediction of SO2 removal efficiency for wet Flue Gas,
01/10/2009· Limestone is generally quite a bit cheaper than other sorbents, making it more popular for large wet FGD systems. The dissolved SO 2 dissociates to HSO 3-, which is subsequently oxidized to SO 4 2-by injected air. Finally, Flue Gas Desulfurization gypsum can be formed as a by-product of whole process. Some studies have been carried out to describe and predict the wet FGD process such as,FLUE GAS DESULPHURIZATION - cseindia.org,Limestone-based wet FGD systems which can remove 90–99 per cent of SO 2 are the dominant choice for thermal power stations globally11 (see Graph 1: FGD technology global population).
