Flue gas desulfurization gypsum (FGDG) is an industrial by-product generated during the flue gas desulfurization process in coal-fired power plants. Due to its abundance, chemical and physical properties, FGDG has been used in several beneficial applications.
Flue gas desulfurized gypsum (FGDG) is an industrial by-product discharged from thermal power plants, smelters, and large-scale enterprise boilers. It is produced when sulfur is removed from flues gases in the flue gas desulfurization (FDG) system, and the formation processes are shown by the following equations (Liu et al., 2021).
The two types of gypsum samples used in this study were obtained from a commercial coal-fired power plant. Both samples were collected from a double-contact flow-type desulfurization equipment. Table 1 presents the values of total mercury and carbon content. These values depend on the type of coal and combustion conditions.
