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.
