Engineering Application of SIL Verification for Chemical Safety Instrumented System
To verify whether safety instrumented function can meet the risk reduction requirement or not,the safety instrumented system of a chemical plant must undergo safety integrity level(SIL)verification before the project is put into use.Taking the SIL verification of a chemical plant safety instrumented system as an example,the application of SIL verification in engineering is studied,including the steps and methods of verification.The impact of parameters such as inspection test coverage(CTI)and inspection test interval(TI)on the results are discussed.The verified results can be optimized through reasonably adjusting these parameters.
