Brief Introduction of Sodium Hydroxide Plant
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.
Uses of Sodium Hydroxide Plant:
1. Used in the production of paper and cellulose pulp;
2. For the production of soap, synthetic detergents, synthetic fatty acids and the refining of animal and vegetable oils. 3. The textile printing and dyeing industry is used as a cotton desizing agent, a scouring agent and a mercerizing agent.
4. The caustic soda chemical industry is used to produce borax, formic acid, oxalic acid, phenol, and the like.
5. The petroleum industry is used to refine petroleum products and is used in oilfield drilling muds. It is also used in the surface treatment of alumina, metallic zinc and metallic copper as well as in glass, enamel, tanning, dyes and aspects.
6. Food grade products are used as acid neutralizers in the food industry. They can be used as peeling agents for citrus, peaches, etc., as detergents for empty bottles, empty cans, etc., as well as decolorizing agents and deodorants.
7. Caustic soda can also be used as an alkaline desiccant. Caustic soda is widely used in the national economy, and many industrial sectors require caustic soda. The sector that uses the most caustic soda is the manufacture of chemicals, followed by papermaking, aluminum smelting, tungsten smelting, rayon, rayon and soap manufacturing. In addition, in the production of dyes, plastics, and organic intermediates, the regeneration of old rubber, the production of sodium metal, water electrolysis and inorganic salt production, the production of borax, chromium salts, manganates, phosphates, etc., also use a large number Caustic soda.
Sodium hydroxide is widely used in water treatment. In sewage treatment plants, sodium hydroxide can reduce the hardness of water through a neutralization reaction. In the industrial field, it is a regenerant for ion exchange resin regeneration. Sodium hydroxide is strongly alkaline and relatively soluble in water. Since sodium hydroxide has a relatively high solubility in water, it is easy to measure the dosage and can be conveniently used in various fields of water treatment.
Sodium hydroxide is used in the following subjects in water treatment: elimination of water hardness; adjustment of pH value of water; neutralization of wastewater; elimination of heavy metal ions in water by precipitation; regeneration of ion exchange resins.
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.
