It can be manufactured either directly through a reaction with sulfuric acid or by using gypsum slurry (calcium sulfate). Ammonium sulfate nitrate. A successful mixed salt fertilizer with a higher nitrogen content of about 26 …

Ammonium Sulfate. Ammonium sulfate is a versatile technical salt, used in various applications. It is used for the production of fire extinguisher powders, as nutrient for microorganisms or as hardener in the chip board manufacturing industry. Furthermore, ammonium sulfate serves for the production of flame resistant textiles or papers.

The process generally involves the following steps. Removing excess amounts of sulphur dioxide from acid sludge; neutralizing the acid content of the acid sludge in a reaction zone 50 while maintaining the temperature, acidity and ammonium sulphate concentration within desired limits in said zone: removing oily material from the aqueous solution formed, …

Alum can be created through one of several chemical processes. One is by adding aluminum hydroxide Al (OH) 3 to sulfuric acid H 2 SO 4. The chemical reaction is: 2 Al (OH)3 + 3 H2SO4 → Al2(SO4)3 + 6H2O. Translated to plain english, adding 2 molecules of aluminum hydroxide to 3 molecules of sulfuric acid results in 1 molecule of aluminum ...
