| Abstract: | The disposal of the product is a key process in the Wet Flue Gas Desulfuration(WFGD). The slurry jet WFGD system in Nan Ning Smelting Plant adopted the forced oxidizing CaSO 3 on the spot and dewatering by the vacuum filter. The experiment investigated the oxidation rate in the absorbing tank, tested and compared the slurries whose dewatering properties were different.The result showed that residual CaSO 3 affected the slurry dewatering. To improve the quality of the gypsum, enhancing the oxidation in the absorbing tank is a right choice. |
