Defoamer for Phosphoric Acid Production When we speak of phosphoric acid ( an inorganic weak mineral acid ) the most elemental application that comes to one’s mind is its application in the agricultural and agro-based sector. Phosphorous is a very critical plant nutrient and is the foundation stone to almost every fertilizer. Phosphoric acid is also used in manufacturing supplements given to cattle, pigs, and poultry. Although industries such as soft drinks and detergents find the need of this product, its contribution to the agricultural and agro-based sector is outstandingly remarkable. The phosphoric acid is further converted into three essential phosphate salts, that act as fertilizers. The triple superphosphate (TSP,) diammonium hydrogen phosphate (DAP) and monoammonium dihydrogen phosphate (MAP.)
The production of phosphoric acid Phosphoric acid can be produced by three different methods. Firstly, the wet process, where phosphoric acid is produced by the reaction of phosphate rock and concentrated sulphuric acid inside a series of well-stirred reactors. This process is by far the most commonly opted process. Secondly the thermal process, that includes burning the phosphorus in the air at 1800-3000k inside a furnace. This process yields a richer quality of phosphoric acid, commonly used in industrial sectors such as pharmaceuticals, detergents and food products.
