Production Method of Pure Sodium Hydroxide

There are two approaches of commercial manufacturing of caustic soda: causticization and electrolysis. The causticization approach is divided into soft drink causticization approach and trona causticization approach according to different basic materials; electrolysis technique can be separated into diaphragm electrolysis technique and also ion exchange membrane method.
Soda causticization technique: Soda ash and lime are specifically made into soda ash remedy as well as ash to make lime milk, and the causticization response is executed at 99-101 ℃. caustic soda. The concentrated option is additional boiled and also strengthened to obtain a strong caustic soda item. The causticized mud is washed with water, as well as the cleaning water is utilized for alkalization. That
Na2CO3+ Ca( OH) 2 → 2NaOH+ CaCO3.
Trona causticization method Trona is crushed, liquified (or alkali salt water), cleared up, and afterwards included in lime milk for causticization at 95-100 ° C. The caustic fluid is made clear, vaporized as well as focused to about 46% NaOH concentration, and also the clear liquid is cooled, After the salt is separated out, it is additional steamed and focused. The strong caustic soda item is acquired. The causticized mud is washed with water, which is made use of to dissolve the trona. Its Na2CO3+ Ca( OH) 2 → 2NaOH+ CaCO3 ↓.
NaHCO3+ Ca( OH) 2 → NaOH+ CaCO3 ↓+ WATER.
The diaphragm electrical boat approach adds soda ash, caustic soda, barium chloride improved prep work to the original salt as well as gets rid of contaminations such as calcium, magnesium and also sulfate ions, and then adds salt polyacrylate or caustic bran to the clarification container to speed up rainfall, and also sand purification After adding hydrochloric acid for neutralization, the brine is preheated and afterwards sent out to electrolysis. The electrolyte is preheated, evaporated, salt-separated, and cooled to get fluid caustic soda, which is further concentrated to get strong caustic soda items. The salt mud cleaning water is used to dissolve the salt. That.
2NaCl +2 WATER [electrolysis] → 2NaOH+ Cl2 ↑+ H2 ↑.
The ion exchange membrane layer technique purifies the original salt by the traditional approach. After the key salt water is infiltrated the microporous sintered carbon tubular filter, it is then detoxified by the chelating ion exchange material column for the 2nd time, so that the brine is detoxified. The web content of calcium as well as magnesium in the medium is lowered to less than 0.002%, the secondary polished brine is electrolyzed, and also chlorine gas is generated in the anode chamber. The upper discharge generates hydrogen gas. During the electrolysis process, an appropriate amount of high-purity hydrochloric acid is added to the anode chamber to reduce the effects of the returned OH-, and also the needed distilled water ought to be included in the cathode chamber. The focus of high-purity caustic soda generated in the cathode chamber is 30% to 32% (mass), which can be straight made use of as a fluid caustic soda item, or can be additional steamed to obtain a finished caustic soda item. That.
2NaCl +2 H2O → 2NaOH+ H2 ↑+ Cl2 ↑.
