中文摘要：炼油化工企业储运罐区贮存物料多，运行安全风险大，大多为重大危险源，发生火灾爆炸事故处理难度大，社会影响大。通过储罐事故案例分析和保护层分析方法的运用，来分析事故原因和完善事故防范措施。提出了深入开展罐区隐患排查和治理是炼化企业当前安全生产的重大任务。通过完善储罐测量仪表、设置安全仪表系统、增设切断阀，以及防雷防静电设施完善，解决好罐顶气VOC治理中连通问题，来提升储运罐区本质安全水平。
英文摘要：In the storage and transportation system of refining and chemical plant, there is a large amount of storage material and high risk on operation safety, Most of them are major hazards, and it is difficult to deal with fire and explosion accident, always cause great social impact. Through tank accident case analysis and Application of LOPA analysis method, it is help for analysis the cause of the accident and improves the accident prevention measures. Carrying out the hidden safety investigation and management in the tank farm is a major task of the refining and chemical plant. Through improving tank measuring instrument, setting up the safety instrumented system, increasing the design of shut-off valve, and lightning protection, anti-static facilities perfect, solving the connectivity problem in VOC governance of tank top gas, to enhance the Intrinsic safety level of storage and transportation tank farm.
