Preparation Of Ammonium Sulfate

In industry, ammonia and sulfuric acid are directly used for neutralization reaction, and it is not used much. It mainly uses by-products in industrial production or exhaust gas to be absorbed by sulfuric acid or ammonia (such as sulfuric acid to absorb ammonia in coke oven gas, and ammonia to absorb smelting plants. Sulfur dioxide in the flue gas, ammonia in the production of Capron or sulfuric acid waste in the production of titanium dioxide by the sulfuric acid process). There are also ammonium sulfates produced by the gypsum method (using natural gypsum or phosphogypsum, ammonia, and carbon dioxide as raw materials).
