Chlor-Alkali Products

Chlor-alkali products make everyday life safer, healthier and more convenient

The electrolysis of saltwater simultaneously produces chlorine and akali, enabling this class of practical and valuable chemicals.

OxyChem is a leading producer of chlor-alkali products

Chlor-alkali chemicals serve as critical feedstock for the manufacture of everything from water purification and fertilizers to detergents and pharmaceuticals.

Product Details

Chlorine is one of the most abundant naturally occurring chemical elements. Its unique reactive properties allow it to bond with other chemical elements to form substances that are used in approximately 50 percent of all commercial chemistry. Chlorine is an important building block used to manufacture thousands of everyday products across many industries, including automotive, construction, defense, electronics, food, health care and metal production. It is also essential to public health. Chlorine plays a vital role in keeping the world’s water supplies safe by controlling harmful bacteria and viruses.

To be used in manufacturing, chlorine must first be separated, via electrolysis, from the other elements with which it is combined. In this process an electrical current passes through brine and splits apart the positive sodium and negative chloride ions to form molecular chlorine gas. The chlorine gas is dried, chilled and pressurized or converted to liquid for storage or shipping.

Liquid Chlorine

Liquid Chlorine (Pesticide)

OxyChem produces sodium hydroxide (NaOH) solution, commonly known as caustic soda, through the electrolysis of sodium chloride (salt) brine in diaphragm or membrane cells. Chlorine and hydrogen are co-produced. The caustic soda solution may be clear or slightly cloudy in appearance, depending on the cell process used. It readily absorbs carbon dioxide from the air. It is available commercially as 50% NaOH, but other concentrations can be provided.

Caustic soda has a wide variety of applications in many industries, including pulp and paper, aluminum, soaps and detergents, textiles, petrochemicals and chemical processing.

OxyChem is the largest North American manufacturer of potassium hydroxide (KOH), commonly known as caustic potash. It is produced through the electrolysis of potassium chloride using membrane cell technology, along with co-products chlorine and hydrogen.

A strong alkali, caustic potash is available in both liquid and dry forms. It has applications in fertilizers, batteries, soaps and detergents, specialty glasses and other industrial operations. It also serves as a chemical intermediate for dyes, pharmaceuticals and photographic chemicals.

Hydrochloric acid (HCl) is used in petroleum wells, ore reduction, food processing, as a pickling and metal cleaning agent, for pH adjustment and in general cleaning.

Composed of a single proton and a single electron, hydrogen is the simplest and most abundant element in the universe. OxyChem produces hydrogen gas (H2) as a co-product of its chlorine and caustic soda production. It is available by pipeline to companies that specialize in marketing industrial gases or that burn hydrogen as a fuel.
