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 operability analysis is an effective method of safety analysis widely used in chemical industry. In recent years, its quantitative research has become a trend. In order to realize the quantitative analysis of danger and maneuverability, this paper presents a new method of hazard and maneuverability analysis based on dynamic simulation, that is, the dynamic simulation model is introduced based on the traditional analysis of hazards and maneuverability, Quantitative simulation to make up for the traditional risk and operability analysis quantitative deficiencies. Through the deviation of operating parameters in dynamic simulation model to varying degrees, it is convenient to simulate the deviation of the composition of the guide word from the process parameters in the hazard and operability analysis. The change of the simulation result is the influence of the deviation on the system, so as to realize Quantitative reasoning of danger and maneuverability analysis. In this paper, a new research method based on dynamic simulation of dangerousness and maneuverability analysis method is expounded by the problems of condensation capacity loss and safety valve failure of an extractive distillation column. Finally, the advantages of this new analysis method are summarized based on the case studies, and the research proves that it is an effective and very promising analytical method.
