摘　　要：运用危险与可操作性分析(HAZOP)、保护层分析(LOPA)、安全完整性等级(SIL)评估3种分析方法对无水三氯化铝生产装置进行风险评价。运用HAZOP分析识别装置中的各种潜在危险和危害,并提出合理可行的措施;引入LOPA分析,定量地评估现有的保护措施,使过程风险满足企业的风险可接受标准;通过SIL评估当前的安全仪表系统(SIS)设计是否合理、是否达到了风险降低的目标。In this paper,hazard and operability analysis(HAZOP),protective layer analysis(LOPA)and safety integrity level(SIL)were used to evaluate the risk of an anhydrous aluminum trichloride production plant.HAZOP was used to analyze and identify all kinds of potential risks and hazards in the plant,and to put forward reasonable and feasible measures.LOPA was introduced to quantitatively assess whether the existing protection measures made the process risk meet the risk acceptability criteria of the enterprise.SIL was used to evaluate whether the current safety instrumentation system(SIS)design was reasonable and met the risk reduction objectives.
