Purification of phosphoric acid

The production of higher grade phosphoric acid using fertilizer grade acid is one of Prayon's specialities.

The dearsenification and defluorination of the acid for manufacturing products to be used in animal feeds (such as MCP, DCP) can be achieved by sulfurising and steam-stripping fertilizer acid. These techniques form part of the portfolio of Prayon processes for transforming fertilizer grade acid into products with the highest level of added value.

Higher grades of acid for use in industrial, food or pharmaceutical applications are produced by our patented Prayon solvent extraction process. This process is used in factories built in Brazil, Indonesia, Korea and Morocco as well as in our original plants in Belgium. This solvent extraction process may only be used by our subsidiaries and companies in which we have a stake.
