危险化学品企业基于四区分离的安全风险定量分析(QRA)方法研究

Research on Quantitative Safety Risk Analysis(QRA)Method for Hazardous Chemical Enterprises Based on Four-zone Separation

危险化学品企业实施“四区分离”需要借助安全风险定量分析(QRA)为总图布局提供技术支撑,定量分析过程中输入模型的数据取值是否符合客观实际,将对四区分离方案产生重大影响。本文通过对安全风险定量分析过程中的参数取值、事故场景选择、环境影响等进行分析,对基于四区分离的安全风险定量分析工作具有指导和借鉴作用。

Hazardous chemical enterprises need to implement“four-zone separation”with the help of quantitative safety risk analysis(QRA)to provide technical support for the layout of the general plan,whether the data values of the input model in the process of quantitative analysis are in line with the objective reality will have a significant impact on the four-zone separation program.This paper analyzes the parameter values,acci-dent scenario selection and environmental impacts in the process of quantitative analysis of safety risk,and provides guidance and reference for the quantitative analysis of safety risk based on the separation of four zones.
