Abstract

This paper discusses the availability optimization of CO shift conversion system of a fertilizer plant using Genetic Algorithm. The fertilizer
plant comprises of various systems viz. shell gasification and carbon recovery, desulphurization, CO-shift conversion, decarbonation-CO2
cooling, CO2 removal, nitrogen wash and ammonia synthesis etc. One of the most important functionaries of a fertilizer plant is CO shift
conversion system. The CO shift conversion system of a fertilizer plant has four main subsystems, arranged in series. Considering exponential
distribution for the probable failures and repairs, the mathematical formulation of the problem is done using probabilistic approach and
differential equations are developed on the basis of Markov birth-death process. These equations are then solved using normalizing conditions
so as to determine the steady state availability of the CO shift conversion system. The performance of each subsystem of CO shift conversion
system of a fertilizer plant has also been optimized using Genetic Algorithm. So, the findings of the present paper will be highly
useful to the plant management for the timely execution of proper maintenance decisions and hence to enhance the system performance.

Key words: Performance optimization, CO shift conversion, Genetic algorithm.
