Risk Evaluation Of Vinyl Chloride Unit Of Huasu Company

The production process of vinyl chloride in the chemical production process is relatively representative.The dangers in the production of vinyl chloride are relatively high,and many risk factors may lead to safety accidents,resulting in a large number of casualties and huge economic losses to the enterprise.Therefore,it is necessary to conduct a risk assessment of the vinyl chloride production unit.Based on the research status of safety evaluation of chemical companies at home and abroad,as well as the safety situation of chemical enterprises,according to the relevant safety evaluation theory,risk prevention and control theory and hazard source identification theory,respectively,the production system,storage and transportation system,safety management of vinyl chloride plant The three aspects use the safety system engineering theory to comprehensively identify and analyze the dangerous and harmful factors,and combine the analysis results to integrate the distribution of major dangerous and harmful factors in the production process of vinyl chloride.Secondly,through the research on the identification basis of major hazard sources and the identification process,the paper has carried out the classification of major hazard sources for each production process of vinyl chloride.The entire vinyl chloride production process has been divided into units according to possible accidents.And the choice of safety evaluation methods.In the research on the risk assessment of the production process of vinyl chloride,the paper firstly conducted a qualitative evaluation of the process unit,the hazardous chemical process safety measures unit,the storage and transportation unit and the safety management unit of the vinyl chloride production process through the safety checklist.The risk analysis of the impact of the casualties of the vinyl chloride unit(including the surrounding environment)was carried out using the simulation of the consequences of the accident.Finally,the results of the evaluation are combined with the relevant risk prevention and control theory,from the update and improvement of safety facilities,safety conditions and safety production conditions and equipment facilities improvement and maintenance,maintenance and maintenance of major equipment and special equipment,and safety production management.Four aspects have proposed improvement measures and recommendations for the risk management of Huasu’s vinyl chloride plant.Figure[5];Table[15];Reference[85]...
