In chlor alkali industries three types of electrolytic process are adopted for the production of caustic, chlorine, hypochlorite chemicals :
- Membrane cell process ( louver anode, mesh anodes )
- Diaphragem cell process ( box anode, perforated anode )
- Mercury cell process ( mesh, strip anode, rod, weir anode )
In each process salt ( brine ) solution is electrolyzed by the action of direct electric current, which converts the chloride ions to chlorine.
The reaction is :
2NaCl + 2H2O = Cl2 + H2 + 2NaOH
In all the methods chlorine (Cl2) is produced at the positive electrode ( anode ) and the hydrogen (H2) and Sodium Hydroxide ( NaOH or caustic soda ) are produced directly or indirectly at the negative electrode ( cathode ). Membrane or Diaphragm or Mercury is used to separate the anode products from the cathode products according the process adopted.
