METHOD OF PRODUCING DI-AMMONIUM PHOSPHATE FERTILIZER

摘要

METHOD OF PRODUCING DI-AMMONIUM PHOSPHATE FERTILIZER A novel method is provided to produce di-ammonium phosphate fertilizer by operating a DAP reactor and granulator in such a manner that part of the hot exhaust gases from the DAP reactor are diverted into a vaporizer where liquid ammonia is vaporized for use in the DAP reactor and the granulator. Considerable savings in energy and other advantages are achieved through such operation.
