Aug 07, 2010· sulfuric acid from gypsum CaSO4 ... All industrial sulfuric acid plant deal extensively with rejecting heat from its point of generation and moving it around, some to other parts of the plant and some to outside the plant as a form of cogeneration. The upshot is that a contact process plant is a net generator of heat.
Microbial induced concrete corrosion (MICC) causes massive damage to wastewater plants. Austrian Researchers from Graz present a new solution against the sulphuric acid attack.
Direct preparation of α-calcium sulfate hemihydrate out of sulfuric acid solution by reaction with lime under atmospheric pressure conditions is systematically investigated. Two preparation methods are investigated: one involving addition of dry lime to sulfuric acid solution (standard procedure) and the other involving addition of sulfuric acid solution to slaked lime (reverse procedure).

Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates.In the form of γ-anhydrite (the anhydrous form), it is used as a desiccant.One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum.It has many uses in industry. All forms are white solids that are poorly soluble in water.
The formation and growth kinetics of gypsum during the dissolution of colemanite in aqueous sulfuric acid were studied in a batch reactor by varying the temperature (60–90°C), stirring rate (150–400 rpm), and initial concentrations of the reactants.
