Chlor-Alkali

For the Chlor-Alkali Industry

The Chlor-Alkali industry is one of the largest in the world. Most of the chlorine is manufactured by the electrolysis of brine, a solution of sodium chloride in water, in diaphragm and membrane cells, and occasionally still in mercury cells.

The primary products of the electrolysis of brine are chlorine gas, hydrogen gas, and sodium hydroxide solution (commonly called “caustic soda” or “caustic”) all of which are found in everyday household products such as common salt, bleach and disinfectants.

Hydrogen, a co-product of chlorine and sodium hydroxide, is also able to be used as a zero-emission fuel in plant boilers, thus reducing the carbon footprint of a facility.
