Performance Analysis of the Perhydro-Dibenzyl-Toluene Dehydrogenation System—A Simulation Study

The depletion of conventional energy resources has drawn the world’s attention towards use alternate resources, which are not only efficient but sustainable as well. For this purpose, hydrogen is considered fuel future. Liquid organic carriers (LOHCs) have proved themselves a potential option for release and storage hydrogen. present study aimed to analyze performance perhydro-dibenzyl-toluene (PDBT) dehydrogenation system, hydrogen, under various operational conditions, i.e., temperature range 270–320 °C, pressure 1–3 bar, platinum/palladium-based catalysts. optimum operating conditions selected 320 °C 2 wt. % Pt/Al2O3 suitable catalyst. configuration analyzed based on exergy analysis efficiency, destruction rate (kW), two optimization strategies developed using principles process integration. Based analysis, strategy # 2, where product’s heat utilized preheat feed, utilities consumption minimized, most system. simulated optimized Aspen HYSYS® V10.
