Carbon footprint analysis of calcined gypsum production in

Mar 10, 2018 FGD gypsum represents one of the major sources for calcined gypsum manufacturing on a world scale (Lee et al., 2011). It can be perceived as a waste product formed during combustion of coal. If the coal has a high sulfur content, it is released during high temperature combustion and forms a part of flue gas in the form of sulfur dioxide.

Gypsum is the crystalline chemical compound CaSO4·2H2O. A close chemical relation and frequently occurring with Gypsum is Anhydrite which is CaSO4. Gypsun has wide commercial use because relatively simple heat processing reduces it to Plaster of Paris. While Anhydrite can be converted to Gypsum and thence to Plaster of Paris, the procedure is not simple and is quite costly. Anhydrite

Gypsum can be ground up and "boiled" (calcined) at a comparatively low temperature until 75% of its moisture content has evaporated. When that happens, the rock becomes a fine powder, commonly known as Plaster of Paris. As of 1978, there were five major companies mining gypsum in Michigan; these are shown below. Note the locations of these

What Happens When Calcined Gypsum Becomes Plaster Of Paris

Gypsum rock is converted into gypsum plaster by driving off some of the chemically combined water. Heating gypsum at 120°C for one hour results in a hemi-hydrate (CaSO4. 1⁄2H2O) with three quarters of the water removed. Gypsum plaster sets by chemically combining with water to form solid calcium sulphate dihydrate. What is calcined gypsum?
