Study On Ion-exchange Membrane Caustic Soda Device Safety Evaluation

Chlor-alkali chemical industry is full of high-risk. Ion-exchange membrane caustic soda device develops quickly in recent years, it has made more progress in technology and saving energy. But because of its products in flammable and explosive and poisonous nature, once an accident happens, if the emergency rescue disadvantage, there will be inestimable losses. So we need to carry out safety evaluation study to ion-exchange membrane caustic soda device. How to identify the dangerous factors and control, establish a comprehensive system and effective method, make this thesis has the important practical significance. According to professional experience and evaluation standards, ion-exchange membrane caustic soda device were systematically analyzed tolook for the hazards and the danger point area, it provides scientific basis for accident forecast and emergency rescue, choosing optimization control measures and safety evaluation.This paper by a large number of materials research, discusses the development of domestic and foreign security evaluation status, ion-exchange membrane caustic soda device safety evaluation, Master the production process of main raw material, equipment and facilities by undertakeing field investigations. Identify and analyz the dangerous factors from materials and products, processing and accident statistics analysis. Based on the actual ionic membrane caustic soda production device, according the principle of selection evaluation unit, the device general layout and electrolysis process unit were selected by security checklist, Dow Chemical and the accident consequences simulation method for the qualitative and quantitative evaluation of a conclusion, and security management and technology solutions.
