Aqueous ammonium phosphate solutions can be produced using an apparatus comprising: a fluid reactor having a plurality of inlets at one end thereof suitable for the admission of phosphoric acid, ammonia and water, the inlets being so positioned as to provide for rapid ammoniation of the phosphoric acid with the evolution of heat, to produce a reaction product mixture containing a liquid portion and steam, the fluid reactor having an exit for the expulsion of the reaction products mixture at the other end thereof, by steam generated by the heat liberated in the ammoniation process; a columnar vessel having an outlet at one end and, at the other end, enclosing the exit of the fluid reactor, a plurality of barriers obturating the columnar vessel in a spaced-apart relationship, and having a plurality of apertures therein for the passage of reaction products mixture therethrough; an inlet quench device connected to the columnar vessel for introduction therein of a liquid aqueous quenching fluid; and, a device in communication with the exit of the fluid reactor, for separating steam from the liquid portion of the reaction mixture and removing the separated steam from the apparatus.

Phosphoric acid ammoniation apparatus

Phosphoric acid and ammonia are reacted together with additions of water when necessary in a reaction vessel to form a molten entrained stream reaction mixture to which a water quench is added to produce an ammonium polyphosphate liquid fertilizer.
