Analysis on the Feasibility of Oxidative Dehydrogenation of Ethane with Electrochemical Means
AIChE Annual Meeting
Monday, November 14, 2016 - 10:00am to 12:30pm
An attractive alternative being considered by Ohio University (OHIO), is an electrogenerative oxidative ODH (e-ODH) process, which utilizes solid oxide fuel cell (SOFC) technology with oligomerization and CO2 capture, to convert ethane into a transportation fuel product. The e-ODH process potentially offers significant advantages over current ODH concepts, including co-production of chemicals and electrical power and process intensification through inherent oxygen separation/modularity provided by the SOFC platform. To assess e-ODH process potential, OHIO has developed an Aspen Plus® simulation for a 500 bbl/day system, to evaluate process efficiency and support a preliminary techno-economic study. For this simulation, pure ethane and air both enter the system separately. Ethane reacts with oxygen from air across an SOFC to form ethylene, which is then oligomerized utilizing a zeolite catalyst into transportation fuel product. This presentation will study results including estimates of process efficiency, product costs ($/GGE), and environmental emissions potential.
