Sulfate is the preferred form of sulfur readily assimilated by crops, and ammonium sulfate is the ideal sulfate compound for soil supplements because it also provides nitrogen from the ammonium. The use of ammonium sulfate in large-scale fertilizer formulations has been growing gradually.

Ammonium sulphate is produced in different ways, The major ones are (i) Production from synthesized ammonia and sulphuric acid. (ii) Production of ammonium sulphate fertilizer by the gypsum process is widely used in many developing countries. In this process, ammonia is used along with pulverized calcium sulphate, carbon dioxide and water.

Aug 23, 2016Dry, powdered ammonium sulfate may be formed by spraying sulfuric acid into a reaction chamber filled with ammonia gas. The heat of reaction evaporates all water present in the system, forming a powdery salt. Ammonium sulfate also is manufactured from gypsum (CaSO42H2O). Finely divided gypsum is added to an ammonium carbonate solution.

The primary use of ammonium sulfate is as a fertilizer for alkaline soils.In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth.
Get PriceThe process comprises heating an organic substance at a temperature in which the ammonia and carbon dioxide are degassed, discharging the gases in an aqueous suspension of gypsum to form an aqueous calcium carbonate containing ammonium sulfate solution, separating and removing the insoluble calcium carbonate, concentrating the ammonium sulfate solution until the saturation point by heating and/or

As a result the temperature of the conversion reaction should not exceed 60 C. The discussed conversion process of gypsum is not new.

Calcium from gypsum can help decrease volatilisation loss of ammonium nitrogen from applications of ammonia, ammonium nitrate, UAN, urea, ammonium sulphate, or any of the ammonium phosphates. Calcium can decrease the effective pH by precipitating carbonates and also prevent ammonia loss to the atmosphere by forming a complex calcium salt with

In this option ammonium sulphate is recovered as a by-product resulting in consumption of ammonia/ sulphur based reductants as both these are not regenerated for recycling back to the process. Decomposition of ammonium sulphate by lime boil is quite efficient as 93% decomposition takes place and ammonia is regenerated for recycling.

When the gypsum is applied to the poorly structured land, the calcium in the gypsum displaces the sodium which is holding on to the soil particles. The displaced sodium then chemically combines with the sulphate in the gypsum to form a sodium sulphate solution which is then lost through drainage water.

Common inorganic applications include ammonium sulfate, which is generated in nickel refineries, flue gas desulphurization from coal fired power plants, and caprolactam production used to make nylon. Similarly, FGD gypsum, or synthetic gypsum from flue gas desulphurization at power plants can also be transformed into a granular source of gypsum.

Manufacture of phosphoric acid. Phosphoric acid is made by two processes a) the 'wet' process. b) thermal process. The thermal method normally produces a more concentrated and purer product, but is energy intensive (because of the manufacture of phosphorus itself.
