Ammonium Sulfate

The solution of ammonium sulphate or ammonium nitrate from the regeneration of both the cation and anion exchange columns is combined and sent to the salt plant for evaporation and production of ammonium sulphate or ammonium nitrate fertilizer material along with the existing facilities of the plant.

17 Advantages and Disadvantages of Ammonium Sulfate

Feb 03, 2020Ammonium sulfate fertilizer was one of the first and widely-used nitrogen fertilizers used for crop production. It isn't as common today as it was in the past, but it is still a valuable commodity in regions where the soil lacks enough sulfur and nitrogen to provide a growing foundation.

Ammonium sulphate production by country, 2020

The United States of America is the top country by ammonium sulphate production in the world. As of 2019, ammonium sulphate production in the United States of America was 2.99 million tonnes that accounts for 25.34% of the world's ammonium sulphate production. The top 5 countries (others are Russian Federation, Canada, Japan, and India) account for 61.92% of it.

Production of ammonium sulfate

The ammonium sulfate forms immediately and crystallizes as a solid. In order to obtain an essentially stoichiometric conversion of the reactants to ammonium sulfate without the production of by-products such as ammonium sulfamate (a herbicide), the molar ratio of ammonia:sulfur dioxide should be approximately 2.3:1, or greater.

Ammonium sulfate

Ammonium sulfate is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of ammonia.A high-melting (decomposes above 280℃) white solid which is very soluble in water (70.6 g/100 g water at 0℃; 103.8 g/100 g water at 100℃), it is widely used as a fertilizer for alkaline soils. It has a role as a fertilizer.

Producing ammonium sulfate from flue gas desulfurization

The financial burdens would be reduced if successful high-volume commercial applications of the FGD solid by-products were developed. In this study, the technical feasibility of producing ammonium sulfate from FGD residues by allowing it to react with ammonium carbonate in an aqueous solution was preliminarily assessed.

US4250160A

A process for the production of ammonium sulfate in a multistage contactor (or column) inclusive of liquid cyclone recycle. A gas, or gases, which contains sulfur dioxide, e.g., a flue gas, is contacted with ammonia in an oxygen and water environment in a column comprised of three sections (zones). Sulfur dioxide is contacted in vapor phase in a central section of the contactor with a

Ammonium sulfate and caprolactam: The long goodbye

Ammonium sulfate is an integral part of modern caprolactam production. Substantial quantities of sulfuric acid are used in the manufacturing process, both from the oximation of cyclohexanone (upon which the vast majority of the world's production rests) and because it catalyzes the rearrangement of cyclohexanone oxime to the final product
