Basically, the mixture of ammonium chloride (prepared using several ways) with slaked lime can be helpful in the production of ammonia gas. 4. Manufacturing Dicalcium Phosphate. Calcium hydroxide or hydrated lime is used in neutralization process with phosphoric acid.
Neutralization of phosphoric acids with calcium carbonate results in a slurry that contains DCP in the hydrated form, but heating at 65°C to 70°C is needed to dry the slurry, which results in some of the hydrated DCP becoming anhydrated DCP (CaHPO 4). In commercial DCP, approximately 35% is in the dihydrated form (Table 2).
After filtration, purification and defluorination, this feed grade phosphoric acid is reacted with quick lime or limestone. Thus, anhydrous dicalcium phosphate (DCP) is formed. DCPis used as the main source of phosphorus and calcium,which contains 18.5% phosphorus and 22% calcium. DCP strengthens the skeleton and accelerate birds' growth.
