Reliability modeling for integrated BPCS and ESD system case study: A two-phase gas-liquid separator process

Abstract

This paper addresses the analytical models and statistical methods used to analyze reliability systems that form the basis for evaluation and prediction of the stochastic failure and nonrepairable behavior of complex process control systems, assembled using a variety of components. The reliability model design of a two-phase gas-liquid separator process has been conducted in this study. The quantitative fault tree analysis approach which has been proved to be acceptable and widely applied in many applications of modeling and methods supporting the system integrator and safety engineer not only to identify how subsystems and components could fail and what are the corresponding effects on the whole system, but also to quantify the reliability parameters for complex systems. The results obtained from our case study can be useful as the tools for justifying the design and implement of BPCS&ESD systems.
