Safety reviews and associated LOPAâs or other risk quantification methods frequently conclude that SIL-rated protection is required for these centrifugal pumps. Once required protection level is assigned, the question becomes one of selecting which process variable to use as an initiator. Determination of appropriate initiator(s) requires evaluation of the properties of the contained liquid as well as pressure/temperature ratings of the pump and piping. Calculation of the Process Safety Time is also connected with the initiator selection, and requires knowledge of the power input requirements. This paper describes a methodology for determination of appropriate process variables for use as initiators and the related Process Safety Times.
