Paraffin dehydrogenation and hydrogenation of nitrobenzene to aniline: Optimal design and operating condition

In this study, a radial flow configuration is optimized using NSGA-II algorithm for simultaneous heavy paraffin dehydrogenation and hydrogenation of nitrobenzene to aniline. Main products yield (Olefin and Aniline) and selectivity are maximized as two objective functions. The Shannon's Entropy, LINMAP and TOPSIS methods as three decision making approaches are used to select the final solution of Pareto front. The optimization results are shown that production rate of olefin and aniline enhanced about 36.55 and 4.33 ton/day, respectively, based TOPSIS and LINMAP methods compared with the non-optimized configuration. In addition, selectivity is increased 5.75% in optimized configuration.
