replacement of a steam turbine with an electromotor based on system reliability analysis at the khark petrochemical complex

Today, reliability assessment of production systems is crucial for ensuring continuous production and minimizing operational and maintenance (o&m) costs. one way to assess reliability at the system level is to create a reliability block diagram (rbd) and estimate the failure rates of equipment over their operational periods. this approach is adopted here in this paper, focusing on rbd analysis of different models for oil pump`s driver of turbo-compressor in the methanol plant at khark petrochemical complex (kpc). upon reliability analysis of various alternative rbds a modification is proposed improving system reliability and reducing maintenance costs.
