    Manufacturing process for Phosphoric acid Guichon Valves

    Phosphoric acid – Manufacturing process for Phosphoric acid : 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).

    Phosphoric Acid Essential Chemical Industry

    Phosphoric acid is produced from fluorapatite, known as phosphate rock, 3Ca 3 (PO 4) 2, by the addition of concentrated (93%) sulfuric acid in a series of wellstirred reactors. This results in phosphoric acid and calcium sulfate (gypsum) plus other insoluble impurities.

    The dihydrate phosphoric acid production process was simulated in a benchscale glass reactor. The influences of selected ionic contaminants (Na+, K+, Mg2+, Al3+, F, and Fe3+) on the crystallization of the gypsum byproduct were investigated. Except for fluorine, the presence of the impurities aided gypsum precipitation, with iron and potassium showing the greatest effect.
