Abstract
Process for production of diammonium phosphate from orthophosphoric acid and ammonia. A specially designed inline reactor, a pipe reactor, is used to produce a homogeneous slurry with a lower moisture content than can be produced and pumped utilizing a preneutralizer as used in many prior-art granular fertilizer processes. Because of the lower moisture content of the slurry, drying requirements are eliminated. This eliminates two items of equipment, to wit, a preneutralizer and a dryer, and greatly simplifies pollution abatement since both items are sources of fumes and dust. The equipment utilized in the present process is inexpensive and simple to operate. The products produced are dust-free and of such particle size distribution that they are well suited for subsequent use in producing bulk blends.
