摘　　要：采用危险与可操作性分析(HAZOP)对丙烯精馏单元进行安全风险评价,找出16个偏差产生的原因及事故后果,然后引入保护层分析(LOPA)对丙烯精馏1塔T603压力高、丙烯精馏2塔T604压力高和回流罐V604液位低计算事故场景的发生频率,结果表明现有的安全保护措施能将剩余风险降低至企业可接受水平,为装置的长周期安全运行提供了依据。The safety risk of propylene distillation unit is evaluated by Hazard and Operability(HAZOP),and the causes of 16 deviations and accident consequences are found out.Then Layers of Protection Analysis(LOPA)is introduced to analyze the high pressure of T603,high pressure of T604 and low level of V604 to calculate the occurrence frequency of accident scenes.The results show that the existing safety protection measures can reduce the residual risk to the acceptable level of the enterprise,which provides the basis for the long cycle safe operation of the device.
