Title: Phosphoric acid concentration process
Inventor: RAISTRICK BERNARD
IPC: C01B25/234
Filed: 1959-12-15
Abstract: In a process for concentrating phosphoric acid which has been produced by the "wet process", ammonium ions are added to the acid in such quantity that throughout the concentration the pH value of the acid never rises above 3 and substantially no "monostage" precipitation takes place, and the acid is concentrated by evaporation of water therefrom in a continuous vacuum evaporator in which the acid undergoing concentration is recirculated through externally heated tubes.  The quantity of ammonium ions is usually up to 6% by weight of an acid containing 30% P2O5 before concentration but varies depending on the original acid concentration, the preferred quantity being between 0,4 and 3,5%.  The ammonium ions may be added in the form of an aqueous ammonia solution or an ammonium salt, e.g. mono- or di-ammonium phosphates, or may be formed in situ by adding gaseous ammonia to the acid.
