Product Description

Product Description

 

GYF can provide Line equipment includes a complete line equipment for the following products:calcium oxide, calcium hydroxide,calcium chloride,calcium carbonate,Caustic soda production line.

The following is a description of the caustic soda production line

1. The causticizing method is divided into soda ash causticizing method and trona causticizing method according to different raw materials; Electrolysis can be divided into membrane electrolysis and ion exchange membrane method.
2. Trona is pulverized, dissolved (or alkaline halide), clarified and added to lime milk for causticization at 95~100ºC, and the causticized liquid is clarified, evaporated and concentrated to about 46% NaOH concentration, and the clear liquid is cooled and further enriched after salt analysis. The finished solid caustic soda was prepared. The causticized mud is washed with water, which is used to dissolve trona.
3. The original salinized salt is added to soda ash, caustic soda, barium chloride fine preparation to remove impurities such as calcium, magnesium and sulfate ions, and then sodium polyacrylate or causticized bran is added to the clarifying tank to accelerate precipitation, and hydrochloric acid is added to neutralize after sand filtration. The brine is preheated and sent for electrolysis, and the electrolyte is preheated, evaporated, salted and cooled to obtain liquid caustic soda, which is further enriched to obtain solid caustic soda products.

The production method is as follows:
Preparation of caustic soda by ionic membrane method:(Ion membrane method)
The  brine  is refined  to  saturated brine,  and   32%  caustic  soda  is produced  after electrolysis.
Electrolyzer anode chamber reaction: NaCl- e→ Na+ + 1/2 Cl2 ↑
Cathode chamber reaction of electrolyzer:
H2O + e → OH-     + 1/2 H2 ↑ Na+ +OH- →NaOH
The production of liquid alkali produces chlorine gas, which reacts with soda ash to produce sodium hypochlorite
Cl2+2Na2CO3+H2O=2NaHCO3+NaClO+NaCl Cl2+Na2CO3=NaCl+NaClO+CO2
Caustic soda is produced by causticizing:(Diaphragm method)
Soda ash and lime were made into soda ash solution by alkali, lime into lime milk, and causticized  at  99~101ºC .  The  causticized  solution  was  clarified,  evaporated  and concentrated to more than 40% to obtain liquid caustic soda. The concentrated liquid was further boiled and solidified to produce the finished solid caustic soda.
Na2CO3+Ca(OH)2→ 2NaOH+CaCO3↓
