manufacture of ammonium sulphate

Ammonium Sulfate - EPASynthetic ammonium sulfate is produced by combining anhydrous ammonia and sulfuric acid in a reactor. Coke oven byproduct ammonium sulfate is produced by reacting the ammonia recovered from coke oven offgas with sulfuric acidAmmonium Sulfate | Mosaic Crop NutritionAmmonium sulfate [(NH4)2 SO4] was one of the first and most widely used nitrogen (N) fertilizers for crop production. It's now less common but especially
