Abstract
The present paper discusses performance modeling and decision support system for the desulphurization system of a fertilizer plant using the concept of performance analysis and modeling. The fertilizer plant comprises various systems, viz., shell gasification and carbon recovery, desulphurization, co-shift conversion, decarbonation, nitrogen wash and ammonia synthesis, etc. One of the most important functionaries of a fertilizer plant is the desulphurization system. The desulphurization system of a fertilizer plant has five main subsystems arranged in series. The decision support system for desulphurization system has been developed with the help of performance modeling using probabilistic approach. After drawing the transition diagram, differential equations have been generated. The steady state probabilities are then determined. This availability model (i.e., measure of performance) deals with the quantitative analysis of all factors (courses of action and states of nature), which influence all maintenance decisions associated with the desulphurization system. The results of this paper are useful for the performance evaluation of the fertilizer plant concerned.
