Characteristics: 

(1) The total energy consumption is the lowest(compared with 

diaphragm electrolysis and mercury electrolysis). At 4000A/m 

current density, the direct current consumption per ton of 

caustic soda is 7.56-7.92 GJ(2100-2200KWH).

(2) High purity caustic soda, 50-60 ppm sodium chloride per 

50% sodium hydroxide solution.

(3)Easy to operate and control

(4)Greater ability to adapt to load changes.

(5)Require high quality brine

(6)Ion-exchange membrane caustic soda is more expensive
