| CLIENT | Hubei Lituo Chemical Technology Co., Ltd. |
| PROJECT | Green, High-Efficiency, Low-Toxicity Agrochemical Technical Material and New Materials Production Project |
| LOCATION | Zone C, Chemical Industrial Park, Jingzhou Economic and Technological Development Zone, Jingzhou City, Hubei Province, China |
| COMPLETION | In Progress |
| PRODUCTION | – 32% Liquid Caustic Soda – 50% Liquid Caustic Soda – 31% Hydrochloric Acid – 12% Sodium Hypochlorite – Liquid Chlorine |
| WORK SCOPE | Construction Drawing Design |
| TECHNOLOGY | The process adopts organic membrane filtration (without pre-treatment or clarifier) for primary brine purification, chelating resin towers for secondary brine treatment, high-current-density natural-circulation bipolar ion-exchange membrane electrolyzers for electrolysis, and two-in-one synthetic furnaces (without steam byproduction) for hydrochloric acid synthesis. The caustic soda evaporation and flaking section employs a double-effect evaporation process. |
