Production line for sodium hydroxide

Technology Introduction :

The ionic membrane caustic soda technology we supplied is the most advanced one in the world, at present the capacity we supply is from 2,000t/y to 320,000t/y.


There are two preparation methods for caustic soda.

The caustic method and the electrolysis method.

The modern industry mainly uses electrolysis saturated NaCl solution to prepare caustic soda. Electrolysis is divided into mercury method, diaphragm method and ion-exchange membrane method, mainly used at present in our country is the diaphragm and ionic membrane method, the main difference between the two lies in the evaporation process of diaphragm caustic soda than the ion membrane method to complex, and the ion membrane method of depleted brine and saline two times the fine business process.


Our service: 

1.As to the production system, we can provide the comprehensive engineering technology like design, construction, technology guidance, turnkey project engineering, production operation and after-sale maintenance and so on, 

2.Also supply the maintenance and reform, upgrade and update of the caustic soda system process and equipment and the electrolyzer according to clients’ requirements; 

3.For the client whose capacity is less than 10,000t/y, we specially make a small size high power density natural circulation zero polar distance ionic membrane electrolyzer and module unit, which has the advantages like less investment and operating expense, less operator etc.


Special advantages:

1、 Easy operation, stable running, meet the requirements of production process, obvious effect of energy-saving;

2、 High purity of product, low energy consumption, less pollution, low operation cost;

3、 Easy production process, long service life of the equipment, less investment cost, the first choice of new-built caustic soda device in the world at present;

4、 Be possible to build matched production device to consume chlorine gas and downstream derivatives of caustic soda, like calcium chloride, MCA, bleaching power, trichloroisocyanuric acid (TCCA), sodium dichloroisocyanurate, chloromethane, ferric trichloride, FAC (Polymeric aluminum trichloride), titanium dioxide and so on.

If you're satisfied with our sodium hydroxide production equipment, welcome to wholesale the high quality products with competitive price from us. As one of the leading manufacturers and suppliers in this profession, we can assure you of its reliable performance.
