Basic characteristics and comprehensive utilization of FGD gypsum

Wet flue gas desulfurization (WFGD) simultaneously removes Hg and SO2 from coal-fired power plant flue gas streams. Hg0 re-emission occurs when the dissolved Hg(II) is converted to a volatile formThe desulfurization gypsum in thermal power plants is mainly produced by the limestone-gypsum wet desulfurization process. The method uses limestone as a desulfurizing agent, and sprays the absorbent slurry into Desulfurization gypsum uses and properties take it
