“…A non-uniform crossover is exploited by DE algorithm for obtaining child vector parameters, where among all parents one is usually being employed more. Employing the components of the existing population members to create trial vectors, the recombination (crossover) operator efficiently shuffles data about appropriate combinations, enabling the search for a better solution space [52].…”

A new thermally coupled microreactor, which simultaneously produces hydrogen and aniline, is simulated. It is suggested that the nitrobenzene hydrogenation process, the heat source, occurs in the tube section, thereby providing the requisite energy for the reactor system. Conversely, the shell section contains the steam reforming of glycerol coolant for the exothermic reaction. The results are evaluated in the two flow directions, namely, cocurrent and countercurrent. The furnace and cooling system, vital for the conventional steam reforming and aniline production processes, are eliminated, respectively, having accurately implemented the sensitivity analysis. Optimization of the most effective parameters is performed via genetic algorithm.

In the current work, a novel process including a multitubular thermally coupled reactor for the simultaneous production of benzene and ammonia is proposed. The ammonia synthesis reaction inside the internal tubes provides the cyclohexane dehydrogenation reaction’s heat demand in the external tube. Moreover, this novel configuration eliminates the required interstage cooler in the conventional ammonia synthesis plant, leading to a remarkable reduction in operational costs. Furthermore, the cyclohexane dehydrogenation process has been employed to supply all of the ammonia synthesis hydrogen demand; therefore, the production, transportation, and storage cost of hydrogen have been greatly reduced. Besides, the danger of hydrogen gas transportation has been avoided. As another advantage of the proposed configuration, cyclohexane conversion in the thermally coupled reactor has been increased from 0.842 to 0.887 compared to a conventional cyclohexane dehydrogenation reactor. Finally, the performance of the proposed reactor has been studied under various inlet temperatures and molar flow rates.
