Fosbrasil S.A. - Cajati - São Paulo - Brazil - Brazilian Producer of Purified Phosphoric Acid
Quimbrasil was "inherited" by Vale. Monsanto Phosphates by ICL. Prayon is still the old and good Prayon.
In 1980 they started talking with partners to a Phosphoric Acid Purification Plant (Solvent Extraction with DIPE plus TBP). The process is exquisitelly complex, as Coca Cola (to cite an important client) is very restrictive, requiring a "special food grade" phosphoric acid with 99,98% purity in a 85% H3PO4 water clear solution (61,5% P2O5).
Ingenious technical financial agreement was made (the project almost was sent to Uberaba).
Erected at 230 km south of São Paulo City, started up in 1987 and is still a Brazil's and South America's market leader.
As this joint venture is located inside Vale´s Chemical Complex, we can see in the right Vale´s Tank Farm and some DCP´s facilities around.
I worked there from 1990 to 2006!
