摘要： Butadiene is formed by dehydrogenation of butenes which are mixed with steam and oxygen then converted to butadiene by oxidative dehydrogenation over a ferritic oxide catalyst, wherein the sensible heat in the oxidative dehydrogenation reaction product is utilized along with heat produced by thermal oxidation of low value volatile products formed to reduce energy requirements and CO2 emissions. Sensible heat is utilized at high temperature for purposes of superheating feed and at somewhat lower temperatures for purposes of vaporizing feed at sequential locations in the process.

摘要： 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.
