Abstract
An apparatus for producing butadiene by way of oxidative dehydrogenation of a butene-rich feed stream includes: (a) a reactor adapted for receiving said butene-rich feed stream and converting butenes to butadiene, thereby providing a butadiene enriched product effluent stream; (b) a superheater coupled to the reactor to receive the butadiene enriched product effluent stream from the reactor as well as being configured to receive reactor feed, said superheater transferring sensible heat from the butadiene enriched product effluent stream to reactor feed and (c) a first feed-vaporizer coupled to the superheater to receive the butadiene enriched product effluent stream as it exits the superheater and to transfer sensible heat from the butadiene enriched product effluent stream to reactor feed. Also provided are (d) a second feed vaporizer; (e) a purification train; and (f) a thermal oxidizer.
