 1. Application                                                                                                                                  

The raw material of chlor-alkali electrolysis is common salt (NaCl). An electrochemical reaction according to the formula :

It causes Cl- ions to be oxidized to chlorine at the anode, while water is reduced to hydrogen and OH- ions at the cathode. To bring this about, specially prepared pure brine is fed into the anode compartment. A cation-selective membrane separates the cathode compartment from the anode compartment. Only hydrated sodium ions can pass through the membrane. With the aid of the electric field, chloride ions are blocked out very well. As a result, the OH- ions combine with Na+ ions in the cathode compartment to form pure caustic soda.

 2. Working principle                                                                                                                 

      The rectifier system is composed of input high voltage switchgear, voltage regulating transformer for on load tap changer(OLTC), rectifier transformer, rectifier, DC switch, cooling water heat exchanger, power factor & harmonic compensation facility. To get higher power factor and lower ripple, 12 pulse configuration is commonly adopted. The system circuit diagram is shown here.
