What is chlorine?
Chlorine, potassium and sodium hydroxide and hydrogen are all necessary for the manufacture of countless vital applications that we rely on, including plastics (especially PVC and polyurethane), solvents, medical products and fire protection.
How it’s made?
Chlorine occurs naturally but not in its elemental (gas) form (as Cl2). Caustic soda (usually as NaOH) is produced as a liquid. These are produced by passing an electrical current through brine (common salt dissolved in water). This is called electrolysis, a process which has been known for over 120 years.
Chlorine & caustic Soda Production
- 3 raw materials go in: salt, water and electricity
- 3 products can come out: chlorine, caustic soda and hydrogen
There are three key ingredients to make elemental chlorine; salt, electricity and water. From these three ingredients, we get elemental chlorine (Cl2), caustic (often sodium hydroxide or NaOH) and hydrogen (H2). As these three products are highly reactive, technologies have been developed to keep them apart.
