Aug 01, 2017· The process The following paragraphs describe a process for diammonium phosphate production from phosphoric acid and ammonia via an ammoniationgranulation process using a pipe reactor. Figure 1 presents a simplified flow diagram of the process. Figure 1.
Process for producing diammonium phosphate (DAP) fertilizer from phosphoric and sulfuric acids, anhydrous ammonia, and water in a specially designed reactor operated at high pressures to granulate diammonium phosphate at low recycle ratios and with relatively small fossil fuel requirement drying per ton of product. Previously operated reactors employed pressures ranging from 0 to 10 psig ...
History of Phosphate Fertilizer • Early sources were mostly animal based ̶ bones, guano, manure • Treatment of bones with acid to increase P solubility started early to mid 1800s • Sulfuric acid treatment process of bones and P minerals (apatite) was patented in mid 1800s. • Today most P fertilizer production

Diammonium phosphate (DAP) (chemical formula (NH 4) 2 HPO 4, IUPAC name diammonium hydrogen phosphate) is one of a series of watersoluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid. Solid diammonium phosphate shows a dissociation pressure of ammonia as given by the following expression and equation:
Diammonium phosphate (DAP) is used as the source of nitrogen and phosphorus for basal applications, and urea for topdressing in most East African sites. The exception is Malawi, where the planting fertilizers is a unique blend (23 N21 P 2 O 5 0 K and .
At Ma''aden, we mine phosphate rock and process it into phosphate products, including diammonium phosphate (DAP) and monoammonium phosphate (MAP), the most widely used phosphate fertilizers in modern agriculture. Our vision is to be among the leading players in the global phosphate trade.
Dap is the abbreviation of diammonium phosphate which is the main raw materials of dap fertilizer production process. Like map, sop, and urea fertilizer, dap fertilizer manufacturing process is a kind of compound fertilizer production line. Therefore, if you want to convert solid powdery dap fertilizer into granular dap fertilizer, Shunxin ...
Ammonium phosphates are consumed almost exclusively as fertilizers, supplying both nitrogen and phosphorus to plants. Driven by population growth and strongly influenced by general economic drivers, global consumption of ammonium phosphate will continue to grow at an average annual growth rate of % during the period 201524.
