Dry Kiln Process Phosphoric Acid

H3po4

Phosphoric acid (H3PO4) can be produced by 3 main commercial methods: wet process, thermal process and dry kiln process. Wet process is by far the most common route and the acid can be used in phosphate fertilizers production (DAP, MAP, SPA) Orthophosphoric acid also forms esters, called organophosphate s. Phosphoric acid is commonly encountered in chemical laboratories as an 85% .
