Abstract
A process is presented for the production of butadiene from a mixture of butane/butene feed. The process provides high conversion of the feed by oxidative dehydrogenation of the feed. The process enables recovery of a good portion of heat inputted from the reaction effluent. The process overcomes equilibrium limitations by oxidative dehydrogenation of butane/butene feed to produce butadiene.
Claims20
A process for the production of butadiene, comprising:
- passing a feed stream comprising butanes and butenes to an oxidative dehydrogenation reaction unit to generate an effluent stream comprising butanes, butenes and butadiene;
- and
- passing the effluent stream to a dehydrogenation unit to generate a process stream comprising butadiene.
A process for the production of butadiene, comprising:
- passing a feed stream comprising butanes and butenes to an oxidative dehydrogenation reaction unit to generate an effluent stream comprising butanes, butenes and butadiene;
- passing steam and oxygen along with the feed stream to the oxidative dehydrogenation reaction unit;
- passing the effluent stream to a dehydrogenation unit to generate a process stream comprising butadiene;
- and
- passing the process stream to a heat and product recovery unit to generate a crude C4 product stream.
