摘要：

为提升危险和可操作性分析(HAZOP)在化工运行装置中的应用效果,并加以改进,结合现代大型化工装置10年来HAZOP实践经验,提出联合分析方法。首先,研究工艺过程参与者行为因素,建立过程风险关注度模型;然后,提出工艺偏差漏斗,利用数学模型筛选出全系统可能的偏差趋势和风险因素,经过人工进一步确认后列入HAZOP分析重点;最后,综合各专业资源输出HAZOP报告,进而形成人机互补和层层筛选的方法集合。结果表明:联合分析方法可提高HAZOP的可持续性,提升化工运行装置风险辨识的准确性,进而提升企业的安全绩效。

Abstract:

In order to improve application effect of HAZOP in chemical operation units, based on the practical experience of its application in modern large chemical plants over the past 10 years, a joint analysis method was proposed. Firstly, behavioral factors of HAZOP participants were studied and process risk attention model was established. Then, its deviation funnel was put forward, possible deviation trends and risk factors of the whole system were identified by using mathematical model before they were manually confirmed and listed into key points of HAZOP. Finally, a HAZOP report was generated by synthesizing various professional resources, and then a method set featuring man-machine complementarity and layer by layer screening was formed. The results show that the joint analysis method can improve HAZOP sustainability as well as risk identification accuracy of chemical operation units, therefore upgrading safety performance of enterprises.

Key words: hazard and operability analysis (HAZOP), chemical running unit, process deviation, attention model, deviation funnel
