In this study, three multi-tubular thermally coupled reactor containing the isobutane dehydrogenation in the shell side and the nitrobenzene hydrogenation in the tube side has been investigated, which resulted in the elimination of the isobutane dehydrogenation furnaces and nitrobenzene hydrogenation coolers. Both processes are available in petrochemical plants. Isobutane dehydrogenation produces isobutene, while nitrobenzene hydrogenation reactions produce aniline as the main product, which is a known intermediate for the production of medicine, dyes, pesticides, and other intermediates. A steady-state homogeneous one-dimensional model is developed to predict the proficiency and operability of the proposed configuration against the conventional process. Further to energy saving, the isobutene conversion in the proposed scheme increases by 6.2% compared to conventional isobutane dehydrogenation.
