Properties of FGD Gypsum

 · Properties of FGD Gypsum FGD scrubber material is initially generated as calcium sulfite; but We Energies'' plants use wet FGD systems that utilize calcium-based sorbents and forced oxidation that converts calcium sulfite (CaSO 3) to calcium sulfate (CaSO 4).).

Low water FGD technologies

FGD capacity. Semi-dry processes account for less than 10%, and the dry processes for a smaller proportion. In addition, some multi-pollutant systems capture SO 2. Large amounts of water are used in coal-fired power plants, with wet scrubbers commonly the ...

Calcium Sulphite

Van Ness et al. (1979, 1981) describe the application of a demonstration dual alkali FGD process, operating in the concentrated mode, to a 300 MW utility boiler. Operating experience with a dual alkali process treating flue gas from a 265 MW utility boiler is described by Durkin et al. (1981) .

The Flue Gas Desulfurization Process: Staying ELG-Compliant

The Flue-Gas Desulfurization (FGD) process utilizes a set of technologies to remove sulfur dioxide (SO 2) from the flue gas emissions of coal-fired power plants. FGD systems were developed as a response to the exhaust – flue gases – from fossil fuel-burning plants, principally coal-burning, that posed both an environmental and human health hazard.

Removal of High-Concentration Sulfate Ions from the Sodium Alkali FGD Wastewater Using …

Abstract The feasibility of removal of sulfate ions from the sodium alkali FGD wastewater using the ettringite precipitation method was evaluated. Factors affecting the removal of sulfate ions, such as NaAlO 2 dosage, Ca(OH) 2 dosage, solution temperature, anions (Cl −, NO 3 − and F −), and heavy metal ions (Mg 2+ and Mn 2+), were investigated, and the optimal experimental conditions for ...

FGD Gypsum Production Process – Gypsum Association

FGD Gypsum Production Process. Mineralogically identical to natural gypsum, FGD gypsum, or synthetic gypsum, is produced from gas captured within emission control systems at coal fired electric utilities. An emission that would compromise air quality, sulfur dioxide (SO 2) gas, is the primary contribution coal makes to FGD gypsum.
