Bezzar et al . (2005) compared the efficacy of microabrasion obtained by two types of acid: 37% H 3 PO 4 and 18% HCl.phosphoric hydrochloric route - ruitersportwatte.be,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 - Chemical Economics Handbook (CEH,

Consumption of phosphoric acid for its acid properties is relatively small (e.g., treatment of metal surfaces, beverage acidulation). Phosphoric acid is the leading intermediate product or processing step between phosphate rock andPhosphoric acid. Synthetic WPA acid — Sandvik,Phosphoric acid, Wet-process acid. From a corrosion point of view, wet process phosphoric acid (WPA) is a rather complicated chemical. The reason is that it usually contains large amounts of impurities, some of which are activating and others will inhibit the corrosion process.Phosphoric acid – Manufacturing process for Phosphoric acid,Thermal process phosphoric acid is of a much higher purity and is used in the manufacture of high grade chemicals, pharmaceuticals, detergents, food products, and other nonfertilizer products. The last method, using a rotary kiln, is a promising alternative because of its reduced environmental footprint and potential cost saving.

The so called thermal process produces a pure phosphoric acid at the expense of very large energy consump-tion. The wet process phosphoric acid (WPA) is produced by a chemical reaction of the phosphate rock with a mineral acid [1–3]. This method is known to be the most economical way of getting phosphoric acid [1].

Is Hydrochloric Acid or Phosphoric Acid Better for Scale,

Hydrochloric acid is a much stronger acid than phosphoric acid. This means that in solution, virtually all the hydrochloric acid molecules will have donated a hydrogen ion to a water molecule, while in a phosphoric acid solution, only a fraction of the phosphoric acid molecules have given up their hydrogen ions.,,
