Product Details
Name: 32% Liquid Caustic Soda Production Line
Source: 32% caustic soda is directly produced by ion‑exchange membrane electrolysis of sodium chloride (NaCl) and water (H₂O)
Process: Ion‑exchange membrane brine electrolysis process (primary native product of chlor‑alkali unit)
Properties: Strong alkalinity and high corrosivity; good fluidity, not easy to crystallize at ambient temperature; low impurity content for ion‑exchange membrane process.
Production Process of Liquid Caustic Soda Production Line
1. Raw materials: Sodium chloride (NaCl) + Water (H₂O), electrolyzed in ion‑exchange membrane electrolyzer
2. Main outputs: 32% caustic soda solution, chlorine (Cl₂), hydrogen (H₂)
Major Application Fields of Liquid Caustic Soda
1. Paper‑making industry: Wood pulp cooking and pulping;
2. Textile printing and dyeing: Desizing, scouring and mercerizing processes;
3. Water treatment industry: Wastewater pH adjustment and acid wastewater neutralization;
4. Chemical synthesis: Production of sodium hypochlorite, various sodium salts and fine chemical intermediates;
5. Daily‑use chemical industry: Raw material for soap and detergents;
6. Metallurgy, alumina production and metal surface cleaning treatment.
Core Equipment of Liquid Caustic Soda Production Line
1. Brine refining system: Salt dissolving tank, filter, chelating resin tower
2. Electrolysis section: Ion‑exchange membrane electrolyzer, rectifier transformer
3. Caustic liquor circulation and storage tanks: 32% liquid caustic soda storage tank, transfer pump
4. Chlorine and hydrogen treatment system: Chlorine cooling and drying unit, hydrogen washing unit
5. Waste gas treatment and DCS automatic control system
