Analysis and Simulation of Dihydrate Process for the Production of Phosphoric Acid (Reactor Section) conditions of the phosphoric acid plant for a given phosphate rock feed flow rate, chemical composition, and supersaturation of calcium sulfate occurs, leading to gypsum crystallization
Phosphorus is an essential plant nutrient and is taken up by plant roots, usually as the dihydrogenphosphate ion, H 2 PO 4, derived from phosphoric acid, H 3 PO 4.The manufacture of fertilizers that are used to rectify phosphorus deficiencies in soils depends on the availability of supplies of phosphoric acid.

A firstofakind, 30,000 t/y solution purifiion plant using this technology successfully started up in 1996 to produce high quality Technical Grade Acid suitable for fertigation and other industrial purposes. Process Advantages: A high value added product is manufactured from wet process phosphoric acid. No solvents are used in the process.
Technical Support Document for the Phosphoric Acid Production Sector: Proposed Rule for Phosphate rock is also used to produce triple super 2. Total Emissions Combined, the 14 phosphoric acid plants in operation in 2006 emitted 3.8 MMTCO2e. Process emissions from phosphoric acid production in 2006 totaled 1.17 tons CO2
The heat recovery system of a conventional sulphuric acid plant recovers most of the heat produced during the sulphur combustion and the SO 2 > SO 3 conversion, producing 1.2 ÷ 1.3+ tons of MP superheated steam (at 25 ÷ 42 bara and about 400°C) per ton of sulphuric acid.
Therefore, a typical plant can expect a savings of more than $35,000 per year by using the higher concentration of sulfuric acid. Design Considerations. While selecting the proper piping material is critical for smooth operation in water treatment plants, it is also important to consider the piping design and installation method.

As part of the Phosphoric Acid portion of a massive fertilizer production facility at the multibillion dollar greenfield Minerals Industrial City (now known as Ras Al Khair), TNT was responsible for the design and supply of two parallel complete Super Portable® tailings stacking systems.
JDCPhosphate Inc. has announced that it has successfully used its proprietary improved hard process (IHP) technology to produce high quality superphosphoric acid (SPA) using low quality phosphate rock tailings without creating toxic phosphogypsum waste during continuous operation of its new demonstration plant in Fort Meade, Florida, US.
Wet process phosphoric acid plants are the most common means of converting phosphate to a soluble form. The principal chemical reaction that occur''s during the wet process is the digestion of tricalcium phosphate using concentrated sulfuric acid. The reaction yields a dilute phosphoric acid solution and synthetic gypsum crystals.
Metallurgical Acid Plants Impact on Metallurgical Acid Plant Design • Acid plant operation is at the mercy of the upstream metallurgical operation. • Variations in flow require constant adjustment of blower to maintain upstream draft. Consider the use of VFD motors for higher efficiency. • Higher gas strengths means that energy recovery
excess consumption of acid in phosphoric acid production • Low Fe 2O 3, Al 2O 3, and MgO contents (below ~5%) to avoid formation of intermediate products • Low Clcontent (<500 ppm) to prevent equipment corrosion. Ore grade in the phosphate mining industry is one of the primary criterion used to differentiate phosphate ores.
Concentrating phosphoric acid. The design has been specially thought out to make it easier to remove or replace the tubes, which in turn makes cleaning the equipment easier. The tubes have also been designed to enable a good transfer of heat between steam and acid. This technique is also particularly useful for producing super

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

Sulfuric 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 grid. Some sulfuric acid may be sold separately as a product.
sulphuric acid, results in the evolution of hydrogen, and the formation of iron sulphate, which will normally settle to the bottom of the tank. Depending on several factors, including temperature and the residence time of the acid in the tank, the iron content of electrolytic grade sulphuric acid may increase to beyond acceptable limits.
