Chlorine Production Processes

Chlorine is produced by passing an electric current through a solution of brine (common salt dissolved in water). This process is called electrolysis.

The three chlorine electrolysis technologies are

• the membrane cell process, nowadays most widely used in Europe,
• the mercury cell process, being phased out worldwide because of the toxic character of mercury and
• the diaphragm cell process.
