a novel thermally coupled reactor‏‎ configuration comprising ‎dehydrogenation of isobutane and aniline production

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#‎
