Potassium hydroxide is used in the refining and petrochemical industries.Potassium hydroxide (KOH) is a white mineral solid that exists in liquid and solid form. It is a strong base that can be dissolved through a chemical reaction. It is a highly moisturizing substance, meaning that water molecules Absorbs and retains it from the environment, making it a useful laboratory desiccant (dryer), a chemical that acts as a catalyst in biodiesel production, as a water softener in detergents It works in the manufacture of optical and crystal glass, photographic compounds, latex rubber and paints.In addition, potassium hydroxide solids are used to produce degreasing and cleaning solvents, lubricating additives, corrosion inhibitors, and other potassium-based salts.In food industry applications, it acts as an acidity regulator and as a inhibitor for the production of potassium sorbate and other food preservatives.This material, corrosive to metals and textures, non-combustible, used in the manufacture of chemicals, oil refining, cleaning compounds.Dry KOH is formed by drying the liquid KOH that is formed during the electrolysis process. Solid KOH is offered in various shapes and concentrations such as 90% and 95% shells or 85% pellets.Solid potassium hydroxide is used as an intermediate in a wide range of production processes, from the production of drugs and fertilizers to its use in oil refining. In addition, it is a precursor to other potassium compounds.
It all starts with crude oil and natural gas (a mixture of hydrocarbons and small amounts of impurities in many parts of the world in varying amounts and compositions).They formed millions of years ago as a result of slow and long processes of rotting plants and animals and were buried under tremendous pressure deep in the earth’s crust.Crude oil and natural gas are extracted from land, land or under the oceans by sinking oil wells. They are then transported to refineries by ship or by pipeline, a line equipped with pumps, valves and other control devices that are particularly suitable for the movement of liquids and gases this is a Applications of potassium hydroxide.
Petrochemical: The purpose of converting some distillation parts (raw materials known as raw materials) into marketable petroleum products. It is made up of three different types of “downstream” processes that change the molecular structure of hydrocarbons:
Cracking (by breaking down heavy oil molecules into lighter, more valuable parts)
Composition (by joining them to form larger molecules)
And deformation of fractions (by transforming them into higher quality molecules).
The purpose of refining and then petrochemicals is to convert natural raw materials into everyday products with applications such as ships, telecommunications, textiles, cosmetics, transportation and construction.
Basic chemical refining which includes: refining of petrochemicals (derived from oil), polymers (derived from petrochemicals) and basic minerals.
Production of special chemicals, including items in paints and inks and items that help protect the product.
Oil and Gas: The oil and gas industry relies on emulsion brittle chemicals that purify oil liquids, bottom tanks and disposal wells. Disinfectants that control hard, soluble solids at high temperatures. Corrosion inhibitors for applications such as re-injection wells, refineries and transportation lines to extend the service life of these assets.
Potassium hydroxide in the refining and petrochemical industries, in addition to reducing chemical costs, helps companies achieve sustainable goals by promoting beneficial reuse. Recyclable cast iron products are cost-effective solutions for a variety of industrial applications, including:Soda or sulfur cosmetics, caustic soda and white liquor substitutes, alkaline sources are used to regulate the pH.
Some well-known refining and petrochemical operations include the use of various chemical products:
Alkylation: The purpose of alkylation is to produce a high quality engine fuel mixture.
This process involves low-temperature reaction conditions in the presence of strong acids. In the alkylation unit, hydrofluoric acid (HF) (estimated at more than 75% use) or sulfuric acid (H2SO4) (estimated at approximately 20%) is used as the catalyst.Potassium hydroxide (KOH) is also used for further treatments at the end of the hydrofluoric acid alkylation process.In the oil refining process, sulfuric acid is the most common acid treatment process. Sulfuric acid treatment leads to partial or complete removal of unsaturated hydrocarbons, sulfur, nitrogen and oxygen compounds, and resin and asphalt compounds. It is used to improve odor, color, stability, carbon residues and other properties of oils. Treatment of acid-refined clay and lime removes traces of asphalt and other compounds that improve the color, odor and stability of the product. Caustic treatment with potassium hydroxide to improve odor and color by removing organic acids (naphthenic acids, phenols) and sulfur compounds (mercaptans, H 2) is done by one wash.By combining caustic soda solution with various solubility promoters (eg, methyl alcohol and cresol), up to 99% of all mercaptans as well as oxygen and nitrogen compounds can be dissolved from petroleum components.
