摘　　要：危险与可操作性分析是化工领域中广泛应用的安全分析的有效方法,近年来其定量化研究已经成为一种趋势。为了实现定量化的危险与可操作性分析,本文提出了基于动态模拟的危险与可操作性分析的新型方法,即在传统的危险与可操作性分析的基础上引入了动态模拟模型,利用动态模拟的定量化弥补传统危险与可操作性分析定量化不足的缺陷。通过对动态模拟模型中操作参数进行不同程度的拉偏可以方便地模拟危险与可操作性分析中引导词与工艺参数组成的偏差,模拟的结果变化就是偏差对系统所造成的影响,以此实现危险与可操作性分析的定量化推理。本文利用对一个萃取精馏塔的冷凝能力缺失和安全阀失效问题阐述了基于动态模拟的危险与可操作性分析方法的新型研究方法。最后,根据案例分析总结了这种新型分析方法的优点,并且研究证明其为一种行之有效且非常有潜力的分析方法。Hazard and Operational Analysis is a widely used effective safety analysis method in chemical engineering field.The research of HAZOP tends to be quantitative recent years.In order to realize quantitative HAZOP,the dynamic simulation based HAZOP was proposed in this paper. Dynamic simulation is introduced into traditional HAZOP and the quantitative trait of dynamic simulation can just make up the deficiency of HAZOP in quantification.The deviation composed by guide word and process parameters can simulated by change parameters of dynamic simulation in different degree,while the corresponding results reflect effects of the deviation,this realize quantitative deduction of safety analysis.This article demonstrates the application of this novel method on an extraction distillation column.After analysis upon the case,the advantages of this novel method are concluded and the result shows it as an effective and promising technology.
