Phosphoric Acid

On a daily basis, 900-1300tons of diluted phosphoric acid is produced through a reaction between phosphate ore and sulfuric acid produced at the Industrial Complex using Prayon Wet Process. Phosphate is trucked in from various mines and unloaded in the unloading station. The production capacity of which is 18,000tons They also have a yard for phosphate storage with a capacity of 100,000tons. Phosphate is transported by moving belts to the phosphate mill at a rate of 200tons per hour to grind phosphates to a granule size less than 500 microns.
Granules react with sulfuric acid in a reactor that has capacity of 1,250m3. In addition there is the new reactor containing diluted phosphoric acid and gypsum. Then the mixture is pumped into 3 hosts, the size of each is 280m3 so as to increase the size of the gypsum crystals and then filtering the solution using a UCEGO Filter.

Phosphoric Acid

The produced diluted phosphoric acid is sent to dilute acid tanks to become concentrated at a later stage. As for the gases resulting from the reaction which contain many fluorine compounds, water vapor and carbon dioxide, they are washed in the absorption towers before being released to the atmosphere. The concentration of diluted phosphoric acid is increased by means of heat exchangers from 28% to 52% using vacuum evaporation in the three connection lines. Some acid is purified for exportation and to be solid in the local market. In addition, the Japanese Fertilizer Company is provided with phosphoric acid to meet its needs. Yet, the bulk of acid is used in the production of fertilizer. Phosphoric acid is an intermediate component in several industries, including fertilizers, animal feed, chemical detergents, as well as in some food industries. Direct benefits of pyroxenite same MgO and high silica as Dolomite are as follows.

Sulfuric Acid

More sulfuric acid (H2SO4) is produced in the world than any other chemical. Over 40 million tons (4 x 1010 kilograms) of sulfuric acid is manufactured annually. Sulfuric acid is used in the production of fertilizers, explosives, petroleum products, detergents, dyes, insecticides, drugs, plastics, steel, storage batteries, and many other materials. The largest amount of sulfuric acid is used in the production of phosphate fertilizers. In this process calcium phosphate, Ca₃(PO₄)₂, in phosphate rock, which cannot be used by plants because of its insolubility in groundwater, is converted to forms that will dissolve in water, thus making the phosphate available to plants.

BULK Sulphuric Acid

One remarkable property of sulfuric acid is its great affinity for water. For example, when it is mixed with sugar, it dehydrates the sugar (takes the water out) and forms a column of black carbon. Because of this high affinity for water, sulfuric acid is often used as a drying agent in the production of explosives, dyes, detergents, and various anhydrous (water-free) materials. The violence with which sulfuric acid and water combine makes the dilution of concentrated sulfuric acid potentially hazardous. The addition of water to the concentrated acid produces a vigorous reaction, which often causes acid droplets to spew in all directions. For obvious reasons, this must be avoided. Always add the acid to water when diluting so that any accidental splattering will involve dilute acid rather than concentrated acid.

Caustic Soda Lye

Caustic soda lye also known as Sodium hydroxide and is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na+ and hydroxide anions OH− Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water, and readily absorbs moisture and carbon dioxide from the air. It forms a series of hydrates NaOH•nH crystallizes from water solutions between 12.3 and 61.8 °C. The commercially available "sodium hydroxide" is often this monohydrate, and published data may refer to it instead of the anhydrous compound. As one of the simplest hydroxides, it is frequently utilized alongside neutral water and acidic hydrochloric acid to demonstrate the pH scale to chemistry students.

Sodium carbonate, Na2CO3, (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na2CO3 and its various hydrates. All forms are white, water-soluble salts. All forms have a strongly alkaline taste and give moderately alkaline solutions in water. Historically it was extracted from the ashes of plants growing in sodium-rich soils. Because the ashes of these sodium-rich plants were noticeably different from ashes of wood (once used to produce potash), sodium carbonate became known as "soda ash." It is produced in large quantities from sodium chloride and limestone by the Solvay process.

Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation (Na+) and a bicarbonate anion (HCO3−). Sodium bicarbonate is a white solid that is crystalline, but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate). The natural mineral form is nahcolite. It is a component of the mineral natron and is found dissolved in many mineral springs.

Ammonium carbonate is a salt with the chemical formula (NH4)2CO3. Since it readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling salt. It is also known as baker's ammonia and was a predecessor to the more modern leavening agents baking soda and baking powder.
Orex is supplying food grade Ammonium Carbonate to Middle East. Specifications as follows.
