Analysis of various factors of reliability using Boolean function technique in refinery unit

Abstract

For the system of multistation elements, the problems of developing Boolean reliability model has acknowledged on the basis of algebra of groups of incompatible events. The objective of this paper to find the various reliability factor of refinery unit which is a subunit of Vacuum Distillation Unit (VDU). The subunits used in the considered unit are Pump, Desalter, Furnace, atmospheric fractionator and gas separator and these subunits are connected through pipes. The reliability factor and mean time to failure (MTTF) is Exponentially and weibully distributed. We illustrate the use of technique by means of examples and introduce numerical results.
