PHOSPHORIC ACID [TECHNICAL] FROM CRUDE PHOSPHORIC (CAP: 5 MT/DAY)

[EIRI/EDPR/4613] J.C.: 2830XL

Phosphoric acid (PA) is an important industrial chemical used as an intermediate in the fertilizer industry, for metal surface treatment in the metallurgical industry, and as an additive in the food industry. Wet-process PA (WPA) is produced by the attack of sulfuric acid (H2SO4) on phosphate rock (PR). Other wet processes use HCl and posterior solvent extraction technology. The corrosivity of phosphate ores, during the production of WPA, depends on two main factors: the chloride content and the interaction between HF formed in the WPA reaction slurry with SiO2, Al2O3, and MgO present in the ore. Many forms of corrosion, mainly localized, are encountered in the PA production plants and facilities such as erosion-corrosion (EC), selective corrosion, pitting, stress-corrosion cracking, intergranular corrosion, and corrosion at high temperature. Laboratory and plant corrosion tests were performed to recognize the corrosion types; EC measuring instruments were developed, built, and applied. The PA industry is spread out worldwide in Europe, Asia, Africa and America, including countries that operate PR mines and produces PA, phosphatic fertilizers, and phosphate-based products.

Phosphoric acid also known as other phosphoric acid (H3PO4) is an important acid, being used, vary widely in the 'Fertilizer Industry (Phosphatic Fertilizers). Phosphatic fertilizers, certainly, affect the growth and contents of agricultural products.  Thus, this product is of high level significance.
