Abstract
A process is presented for the oxidative dehydrogenation of butenes to butadienes. The process includes the use of parallel reactors, wherein the reactors are operated at different pressures. A butene feedstream is split into several portions wherein each portion is passed to a different reactor. Each reactor generates an effluent stream, and the effluent stream is cooled to generate steam for use in a lower pressure reactor.
