Ethylene is an essential building block in the petrochemical industry and it almost exclusively produced via ethane steam cracking, a well-established albeit highly energy carbon dioxide intensive process. The oxidative dehydrogenation of promising alternative to cracking reactions due its exothermic nature, which decreases overall requirements footprint. need capital air separation unit for producing oxygen limits potential industrial application. current study investigates route, i.e. production chemical looping, where released in-situ by suitable carriers. looping dehydrogenation, supported original experimental data, processes are simulated with ASPEN Plus®. A comprehensive analysis economic assessment carried out both processes. Compared state-of-the-art proposed process provides ~28% savings per tonnes ethylene ~21% reduction resulting price. Sensitivity show that economy strongly sensitive feedstock
