Abstract. The reactivity of flue gas desulphurization gypsum with ammonium carbonate has been studied in the temperature range (20–50) °C. Mechanism of this reaction was suggested and the kinetics parameters characterizing the reaction were determined. A mathematical model suitable for the prediction of the conversion of gypsum was proposed.

What are the Pros and Cons of Ammonium Sulphate Fertilizer?

Jul 15, 2019 · Ammonium sulphate fertilizer not only adds general value to the soil via its nitrogen content, but also addresses pH issues in alkaline soils. An inorganic salt, ammonium sulphate is produced by either combining ammonia with sulfuric acid or gypsum and calcium carbonate. The result is an odorless, white powder with average nitrogen and sulphate concentrations of 21% and 24% .

Calcium sulfate - Wikipedia

Calcium sulfate is the inorganic compound with the formula CaSO4 and related hydrates. In the form of γ-anhydrite, 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. Calcium sulfate causes permanent hardness in water.
