Production process

Ion Exchange Membrane Electrolysis Technology:

Salt water is refined according to the traditional method after salt salt salt is salinized. The primary refined salt water is filtered through a microporous sintered carbon tube filter, and then refined by a combined ion exchange resin tower. The content of calcium and magnesium in salt water is reduced to less than 0.002%. The secondary refined salt water is electrolyzed and produced in the anode chamber. The Na + in the salt water of the anode chamber enters the cathode chamber and the 0H of the cathode chamber through the ionic membrane to produce sodium hydroxide, and H + discharges directly on the cathode to produce hydrogen. In the process of electrolysis, appropriate amount of high purity hydrochloric acid was added to the anode chamber to neutralize the returned OH-, and the required pure water should be added to the cathode chamber. The concentration of high purity caustic soda produced in cathode chamber is 30%~32%(mass), which can be directly used as liquid caustic soda product, and can be further boiled to produce the finished product of perimeter caustic soda. 2NaCl+2H2O→2NaOH+H2↑+Cl2↑



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 (2100-2200 kWh);

(2) the purity of caustic soda is high, 50-60ppm sodium chloride in per 50% sodium hydroxide solution.


(3) the pollution of environment caused by mercury or asbestos;

(4) the operation and control are comparatively easy. The ability to adapt to load changes is greater.


(5)require high-quality brine.


(6)the price of ionic membranes is more expensive.
