摘要
安全仪表系统贯穿了整个石化装置的全生命周期,通过对不完美测试及工厂安全仪表失效数据应用的分析,提出在役石化装置安全仪表系统安全完整性等级(SIL)验证的方法及相应的维护管理思路,包括检验测试、建立安全仪表失效数据库、旧仪表或故障仪表替换等措施;探讨了在役石化装置安全仪表系统SIL验证及日常管理应注意的问题。
The safety instrumented system runs through the whole life cycle of the petrochemical plant.Based on the analysis of non-perfect test and the application of failure data of safety instruments in factories,the method of safety integrity level(SIL)verification of safety instrumented system in petrochemical plants in service and the corresponding maintenance and management ideas are proposed,including the countermeasures of inspection test,establishing safety instrument failure database,replacement of old or destroyed instrument.The problems that should be paid attention to in SIL verification and daily management of the safety instrumented system in the petrochemical plant in service are discussed.
