gypsum ratios. Their high availability, long life cycle and easy maintenance, combined with fully automatic operation reflect the latest in stateoftheart technology. In order to minimize energy costs, the exhaust gases from the kettle process are used for the predrying process, so that an additional hot gas generator may not be required.
wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4 ½H 2O), commonly called stucco. A flow diagram for a typical gypsum process producing both crude and finished gypsum products is shown in Figure In this process gypsum is crushed, dried, ground, and calcined.

Oct 06, 2013· Sulfuric acid from gypsum I have made the following research: 2 CaSO4 + 2 SiO2 + C → 2 CaSiO3 + 2 SO2 + CO2 SO2 + O2 (V2OC) → SO3 SO3 + H2O → H2SO4 This dictates that 2720 grams of calcium sulfate would generate 1960 grams of sulfuric acid by theory. The idea is that the gypsum is roasted with sand and coke at high temperatures.
