• Chlor-alkali (also spelled chloralkali or chloro-alkali) is an industrial process for the electrolysis of sodium chloride (NaCl) solutions.
• The chlor-alkali process is a chemical industry cornerstone that uses electrolysis to produce chlorine (Cl2) and sodium hydroxide (NaOH).
• When an electric current is applied to a brine solution, which is usually aqueous sodium chloride, electrolysis occurs. This electrolysis converts sodium chloride molecules into their elemental componentssodium (Na+), chlorine (Cl-), and hydrogen (H2).
• Within the electrolysis cell, a membrane separates the anode’s chlorine gas (Cl2) from the cathode’s sodium hydroxide solution (NaOH).
• Chlorine, well-known for its disinfection characteristics, finds extensive application in water treatment, bleach manufacture, and many industrial processes, whereas sodium hydroxide, generally known as lye or caustic soda, serves in soap and detergent making, paper processing, and metal production.
• With an annual global chlorine production of more than 35 million tons, the chlor-alkali process is critical to meeting the diversified needs of industries around the world.
