Ammonium sulfate factory

Ammonium sulfate, also known as ammonium sulphate, is the earliest nitrogen fertilizer produced and used at home and abroad. Pure ammonium sulfate is colorless orthorhombic crystals. The aqueous solution has a pungent salty taste. The industrial product is white or small yellowish grains. Soluble in water, insoluble in ethanol. It is usually regarded as a standard nitrogen fertilizer, with a nitrogen content between 20% and 30%. Ammonium sulfate is a salt of strong acid and weak base, and its aqueous solution is acidic. The granular nitrogen fertilizer ammonium sulfate factory can provide both ammnoium sufate crystal and granular.

Ammonium sulfate is a nitrogen fertilizer and an acidic fertilizer in inorganic fertilizers. Long-term single use will cause soil acidification and hardening, and needs to be improved. Ammonium sulfate cannot be used in the production of organic fertilizers. Moreover, acidic fertilizers cannot be used together with alkaline fertilizers, as double hydrolysis can easily lead to loss of fertilizer efficiency.

In the 1960s, ammonium sulfate was the main variety of nitrogen fertilizer and one of the main sources of sulfur, a nutrient element for crops. The earliest ammonium sulfate factory was made by neutralizing ammonia and sulfuric acid, but later the proportion of by-product ammonium sulfate is increasing, and now basically all of it comes from other industry by-products in China, such as coking industry, caprolactam, sulfuric acid tail gas desulfurization, power plant desulfurization, Acrylonitrile, methyl methacrylate, zinc oxide and other by-products.

At present, most ammonium sulfate factory in China purchase by-product ammonium sulfate crystals from other industries, and directly repackage or extrude them into ammonium sulfate granules before selling or exporting them. 

Application method of ammonium sulfate:

Ammonium sulfate fertilizer can be used as base fertilizer, top dressing, and seed fertilizer, and top dressing is the most suitable method because its fertilizer effect is the best.
