With the extensive utilization and disposal of flue gas desulfurization (FGD) gypsum, Hg 0 reemission and Hg 2+ dissolution could cause severe atmospheric and groundwater contaminations. The present study employed two precipitating agents: sodium dithiocarbamate (DTCR) and 2,4,6trimercaptotiazine, trisodium salt monohydrate (TMT) to prevent mercury in FGD gypsum from releasing into the ...
Synthetic gypsum produced by wet flue gas desulfurization (FGD) systems on coalfired power plants is commonly used in the manufacture of wallboard. This practice has long benefited the environment by recycling the FGD gypsum byproduct, which is becoming available in increasing quantities, decreasing the need to landfill this material, and ...
A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.

The material is then dewatered and processed; the end product is a consistent, finely divided powder. This process is known as flue gas desulfurization (FGD), and the gypsum produced is known as FGD gypsum. The term FGD gypsum is the name most often used by generators of the material.
Abstract: Recovering gypsum from flue gas desulfurization (FGD) plants is becoming more important as the technical feasibility of substituting FGD gypsum for natural gypsum in traditional applications such as wall board, cement and soil conditioners has been demonstrated.
The desulfurization gypsum in thermal power plants is mainly produced by the limestonegypsum wet desulfurization process. The method uses limestone as a desulfurizing agent, and sprays the absorbent slurry into the tower to fully contact and mix with the flue gas, thereby washing the flue gas, then the SO 2 (in the flue gas) reacts with the ...

This report presents and discusses results from the project ''Fate of Mercury in Synthetic Gypsum Used for Wallboard Production'', performed at five different fullscale commercial wallboard plants. Synthetic gypsum produced by wet flue gas desulfurization (FGD) systems on coalfired power plants is commonly used in the manufacture of wallboard.
the primary byproduct is calcium sulfate, commonly known as synthetic gypsum, or flue gas desulfurization (FGD) gypsum. This synthetic gypsum is used in the manufacturing of wallboard and cement, and as a soil amendment in agricultural and construction applications (Duke Energy, 2017).
