    Preparation of Phosphoric Acid In Industry Phosphoric acid is produced by two general processes: Thermal process and Wet process Wet Process: This process is majorly used in the commercial industry Phosphoric acid is prepared by combining sulphuric acid   For instance, the norm Semi International standards SEMI C360301 gives specifications for phosphoric acid grades 1, 2 and 3 which are suitable for working in the semiconductor field Methods for producing phosphoric acid have been known for a long time Two types of methods are known, viz dry methods and the wet methodsProcess for the production of high purity phosphoric In the synthesis of phosphoric acid by the "wet process" techniques, phosphate rock (for example, apatite) which may be either calcined or uncalcined and which is in an appropriate state of subdivision, is reacted with sulfuric acid, of well established concentrations, at elevated temperatures, generally above 160° FPRODUCTION OF WET PROCESS PHOSPHORIC ACID   Industrial phosphoric acid production makes use of the “wet process”, which consists of two steps: (1) sulfuric acid attack of the ores and (2) separation of the acid from the calcium sulfate hydrate crystals produced as a side product1 The main reaction involved with calcium phosphate dibasic can be Gypsum Crystallization during Phosphoric Acid   Phosphoric Acid Production Last Updated on Sat, 05 Dec 2020 Industrial Wastes The use of the electric furnace process (Fig 11) and acidulation of phosphatebearing rock is made commercially to produce phosphoric acid In the first method, elemental phosphorus is first produced from phosphate ore, coke, and silica in an electric furnace Phosphoric Acid Production Industrial Wastes

      Process Technology of Phosphoric Acid There are two main commercial processes to produce phosphoric acid: the wet process and the dry [] (electrical furnace) processAlthough, the acid produced (technical grade) with the dry process is pure, its production cost is much higher than that of the wet process phosphoric acid (WPPA or fertilizer grade acid)  89 Phosphoric Acid 891 General12 Phosphoric acid (H3PO4) is produced by 2 commercial methods: wet process and thermal process Wet process phosphoric acid is used in fertilizer production Thermal process phosphoric acid is of a much higher purity and is used in the manufacture of high grade chemicals,AP42, CH 89: Phosphoric Acid  The demand for phosphoric acid is therefore a derived demand and the rate of growth in demand for phosphoric acid is largely dependent on the rate of growth in the sectors that use it as an input Production of phosphoric acid increased from 96 million short tons in 1986 to 124 million tons in 1991, a 29 percent increase in five yearsPhasphoric Acid and Phosphatic Fertilizers: A ProfileSulfuric Acid: This acid is produced at phosphate plants for use in reacting with phosphate rock to produce phosphoric acid The heat generated off sulfuric acid production is used to power phosphate manufacturing plants and extra energy is often sold back to the area electric gridHistory of Phosphate Fertilizer Production(*)Two types of insoluble losses occur during the production of phosphoric acid These are cocrystallized losses and unattacked losses The content of each of these losses in the gypsum depends on different parameters including the sulfate content Where there is a high sulfate content in the attack tank slurry, cocrystallized losses are lowTechnologies Phosphoric acid production
