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.
Phosphoric Acid Pilot Plant The purpose of the KEMWorks Phosphoric Acid Pilot Plant is to determine the behavior of phosphate rock under conditions typical of an industrial phosphoric acid plant. Because the chemical composition and mineralogy of phosphate rocks varies widely from deposit to deposit (and usually within a deposit) so will the ...
Phosphoric Acid Plant: The advanced Phosphoric acid production technology Now our company have developed the most advanced phosphoric acid production technology in the world, which is totally different from the traditional production technology, the advantage is to save the cost of investment, reduce production costs, greatly improve the effects on the environment .
Process Technology of Phosphoric Acid. There are two main commercial processes to produce phosphoric acid: the wet process and the dry  (electrical furnace) process.Although, 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).
The number of phosphoric acid plants has been decreasing in recent years (see Table 4-2). Since 1968, nine plants have closed; two plants have opened; and at one plant, capacity has doubled. In addition to a decrease in the number of thermal phosphoric acid plants, there has been a decrease in the utilization of capacity.
Phosphoric acid is an important intermediate chemical product. It is used mainly by the fertilizer industry. In 1980 the world wide production capacity for phosphoric acid yielded about 33 million tons of P2O5 equivalents.
phosphoric acid manufacture have been developed primarily for obtaining high P 2 O 5 recovery and high filtration rate. This is understandable since phosphoric acid is the raw material for fertilizers and therefore the efficiency and cost of the phosphoric acid plant is the main concern. As a matter of fact, the filtration characteristics of the

1,000 ton-per-day P 2 0 5 wet process phosphoric acid plant. Mass and energy balances were calculated and used for preliminary equipment sizing and verification of the technical feasibility of the process. Both capital and operating costs were estimated in evaluating economic feasibility. Capital costs were calculated from equipment quotes obtained
Sulfuric Acid Production Cost Reports - 2018/19 Capital Investment & Operating Cost of Sulfuric Acid Plants. Sulfuric Acid (also known as H2SO4) figures among the most important chemicals. It has a number of large-scale essential uses such as: in the production of phosphoric acid (a key fertilizer), as a pickling agent for iron and steel, as a ...
Fluosilicic acid is reacted with phosphate rock in order to produce wet process phoshoric acid and calcium fluoride which is later reacted with sulfuric acid to produce hydrogen fluoride and calcium sulfate. The hydrogen fluoride is then stripped from the phosphoric acid and recovered as either anhydrous hydrogen fluoride or concentrated hydrofluoric acid or reacted with aluminum trihydrate to ...
Typical capital costs, overall energy efficiencies (based on the heating value of the coal used to produce the power plant fuel), and electricity costs are: phosphoric acid $350-450/kWe, 24-29%, and 11.7 to 13.9 mills/MJ (42 to 50 mills/kWh); alkaline $450-700/kWe, 26-31%, and 12.8 to 16.9 mills/MJ (46more »
Simplot Phosphates had previously implemented plant-expansion projects that increased phosphoric acid production and plant on-stream time. Operating limitations arose due to lower-quality phosphate-rock feed and process scaling issues with the phosphoric acid filters, resulting in excessive downtime for filter washing.
Cost estimates for uranium recovery are developed for both solvent extraction and ion exchange processes. The cost estimates are based on a hypothetical plant adjacent to a phosphoric acid plant. Capital costs are based on adjusted historical (published) ﬁgures. Operating costs represent current costs.

Sep 16, 2018· Impurities vary from 15 to 20% and the venturi scrubber can efficiently collect the acid mist and fine dust discharged in the exhaust from the hydrator. Wet process phosphoric acid is made by reacting pulverized, beneficiated phosphate ore with sulfuric acid to form calcium sulfate (gypsum) and dilute phosphoric acid (see Section 9.2.4).
(2,216 Kg) of H3POtt will be fed to the evaporator for concentration into 448 gallons (1,696 liters) per day of 80% phosphoric acid. The plant is currently paying $218.40/ton for 80% phosphoric acid solution, giving the 3.04 tons of recovered solution a value of $664.00 per day, or $166,000 per year. 20

The Wet Acid Process. The WAP process was first patented in 1842 and represents >90% of all phosphoric acid production today. The core of the WAP process is breaking the strong bonds in fluorapatite (phosphate rock)—between calcium and phosphate ions.
Steam is used mainly for concentration at about 0.5-2.2t.t-1 P2O5 concentrated. When the phosphoric acid plant is linked to a sulphuric acid plant, the high pressure steam that is produced in the waste heat recovery boiler is normally used to produce electric power and the low pressure exhaust steam is used for phosphoric acid vacuum concentration.
