摘要
研究借助GB/T 20438—2006的系统安全完整性理念,在分析了液氯充装系统工艺流程的基础上,建立了液氯充装系统的4个独立保护层并对其进行了安全性分析,根据液氯充装的危险性,确立了液氯充装系统的安全完整性等级为SIL3。从系统安全完整性出发,对系统安全性要求分配进行了探讨,提出了以各保护层失效概率为基础的液氯充装系统安全完整性审核评估,为系统的风险分析评估提供了一种新的思路。
Four independent protection layers of liquid chlorine filling systems are established and their securities are analyzed,according to the integrity concept of system security（GB / T 20438—2006） and technological analyses of liquid chlorine filling systems.Based on the risks of filling liquid chlorine,the safety integrity level of liquid chlorine filling system is determined to SIL3.The allocations of system security requirements are discussed according to the systematic safety integrity,then systematic safety integrity audit assessments of liquid chlorine filling systems are proposed on the basis of failure probabilities of each protective layers,providing a new idea for the risk analyses and evaluations of system.
