化工安全屏障研究进展综述

Research on Chemical Safety Barrier

安全屏障是指为了预防或控制事故的发生而采取的手段,它可以对化工生产的各个阶段进行层层控制与全面保护.本文对安全屏障的起源、发展、定义、功能、分类、绩效评估以及在我国的应用做了详细的研究.研究表明,安全屏障的起源与能量等3种模型相关,安全屏障的发展与LOPA和ARAMIS相关,安全屏障作为物理或非物理手段,它的绩效评估由3项指标构成;国内对安全屏障的应用主要是将其与风险图等模型结合起来,以降低风险,提高安全水平.

Safety barrier refers to the means to prevent or control accidents.It can control and protect all stages of chemical production.This paper makes a detailed study on the origin,development,definition,function,classification,performance evaluation and application of safety barrier in China.The research shows that the origin of safety barrier is related to three models such as energy,and the development of safety barrier is related to LOPA and ARAMIS.As a physical or non-physical means,the performance evaluation of safety barrier is composed of three indicators.The domestic application of safety barrier is mainly to combine it with risk map and other models to reduce risks and improve safety level.
