A process for the production of granulated di-ammonium phosphate containing fertilizer

European Patent Application (EP 0 367 849): 6 pp.
A process for the production of granulated di-ammonium phosphate containing fertilizer
A process for the production of granulated diammonium phosphate-containing fertilizers comprises ammoniation of phosphoric acid in a tubular reactor situated in a drier. The phosphoric acid concentration is preferably 36-50% P2O5. The recycle ratio is <3:1. The ratio between ammonia and phosphoric acid results in ammonium phosphate leaving the tubular reactor having an N:P mole ratio of 1.6-2.0:1. Steam may be added to the granulator to partially agglomerate the recycle particles.
