To meet the Clean Air Act emission standards, many utilities have installed flue gas desulfurization (FGD) equipment or other systems to remove or reduce the particulate and gas emissions of sulfur compounds. This process produces forms of FGD gypsum that are currently used in wallboard products or as a soil amendment in agriculture.
Condition 2 Source of Soluble Sulfate. Gypsum, having the chemical formula CaSO 4 2H 2 O, is a good source of soluble sulfate. Gypsum sources include FGD and wallboard. Considering the high sulfur content in gypsum, small quantities can generate problematic amounts of hydrogen sulfide. Fly ash and bottom ash contain lower

This process produces forms of FGD gypsum that are currently used in wallboard products or as a soil amendment in agriculture.
Gypsum’s natural ability to harden and cake into a cement-like form makes it difficult to remove from equipment. This can be accentuated if gypsum is dried at too high of a temperature, where molecular moisture is being removed, resulting in an undesirable form of gypsum. If this occurs, and the undesirable gypsum is exposed to moisture
Nov 24, 2010· Synthetic gypsum is a common byproduct of fossil-fueled power plants that work to remove sulfur dioxide from flue gases in their effort to curb
Gypsum as Fertilizer. Pure gypsum is 23 percent calcium and 19 percent sulfate (CaSO4-2H2O). In the hierarchy of the 16 essential plant nutrients that begins with non-minerals hydrogen, oxygen and carbon, calcium is seventh and sulfur is ninth. Calcium is the plant nutrient most likely to
Process For Removal Of Sulfur And Ash From Coal Atlantic. Mar 10, 1981 A process for reducing the sulfur and ash content of coal comprising treating coal particles in a hydrocarbon oil slurry with minor amounts of a conditioning agent and water to effect agglomeration of ash and pyritic sulfur mineral matter separating the agglomerates from the slurried coal particles and recovering coal
The sulfur content in coal is usually a few per cent but it can range from less than 05 per cent to as much as 8 per cent or more Much of the sulfur is inorganic in nature occurring in discrete mineral phases; the inorganic sulfur is mostly pyrite with small amounts of sulfates such as gypsum Part of the sulfur in coal is termed organic
