1. A method of producing ammonium sulphate nitrate from ammonium nitrate solution, crystalline or powdered ammonium sulphate and dolomite in an industrial production process, in which the final product is obtained by means of mechanical granulation and screening of the desired fraction, which is subsequently cooled and conditioned, the under-size particles and the disintegrated oversized ...
Also, two types of explosives are produced from ammonium nitrate. The first is a mixture of fuel oil and porous ammonium nitrate granules. The second type is produced by emulsifying small droplets of ammonium nitrate solution in oil. Pan granulation of ammonium nitrate also has been developed commercially (16,17).
The unique process produces the highest quality ammonium sulphate by removal of unwanted sulphur dioxide from utility or industrial boiler flue gas by reacting it with ammonia and air to form ammonium sulphate. This energy efficient process uses the waste energy from the boiler flue gas to crystallise the product by evaporation of excess water.
Both ammonium nitrate and ammonium sulphate are useful as fertilizers. The key difference between ammonium nitrate and ammonium sulphate is that ammonium nitrate is the result of a reaction between ammonia and nitric acid while ammonium sulphate is produced when ammonia reacts with sulfuric acid. Reference: 1. "Ammonium Nitrate."
A process for producing ammonium nitrate is disclosed, which process comprises exposing a gaseous oxidiser feed composed at least substantially of ammonia, steam and an oxidising gas to...

Ammonium nitrate (NH4NO3) has a molecular weight of 80.04 and contains 33.9 percent nitrogen. It is a white, crystalline salt that is highly soluble in water. The solid salt picks up water from the air when the vapor pressure of water exceeds that of a saturated aqueous ammonium nitrate solution; solid ammonium nitrate does not occur in nature.

• Ammonia is also used in the production of nitrogen based fertilizer solutions which consist of ammonia, ammonium nitrate, urea and water in various combinations. • Ammonia is utilised extensively in the fertilizer industry to produce solid materials such as ammonium nitrate, sulphate, phosphate and urea. Other Uses
Ammonium Sulfate Fertilizer Ammonium Sulfate, (NH4)2SO4, is an inorganic salt which is an important source of nitrogen (N) and sulfur (S) for crop nutrition. It can be used as a directly applied fertilizer as well as a component of NPK blends and compound fertilizers. Its nutrient analysis designation for N, P, K and S is --21-24S.
An experimental study indicated that the ammonium oxidization and sulfate reduction efficiencies were increased in the presence of nitrite and nitrate. Studies showed that a decreasing proportion of N/S in the presence of NO 2− at 30 mg·L −1 would lead to high removal efficiencies of NH 4+ -N and SO 42- -S of up to 78.13% and 46.72%, respectively.
