Abstract
Processes and associated reaction systems for the oxidative dehydrogenation of ethane are provided. In particular, a process is provided that comprises supplying a feed gas comprising ethane and oxygen to a multitubular fixed-bed reactor, allowing the ethane and oxygen to react in the presence of an oxidative dehydrogenation catalyst to yield a reactor effluent comprising ethylene; supplying a coolant to an upstream region of an interior shell space of the reactor in a flow pattern that is counter-current with the flow of the feed gas; and withdrawing the coolant from the upstream region and supplying at least a portion of the coolant withdrawn from the upstream region to the downstream region in a flow pattern that is co-current with the flow of the feed gas.
