Abstract
Embodiments described in examples herein provide methods and systems for increasing a yield from an oxidative dehydrogenation (ODH) reactor. An exemplary method includes controlling a temperature of a feed gas composition at less than 250° C. The feed gas composition is flowed through a feed preheater to form a heated feed gas, wherein in the feed preheater the feed gas composition is heated to between 150° C. and 250° C. The heated feed gas is flowed into the ODH reactor less than 15 seconds after leaving the feed preheater.
Claims21
A method, comprising:
- controlling a temperature of a feed gas composition to less than 250° C.;
- flowing the feed gas composition through a feed preheater to form a heated feed gas, wherein in the feed preheater the feed gas composition is heated to between 150° C. and 250° C.;
- and
- flowing the heated feed gas into an oxidative dehydrogenation (ODH) reactor less than 15 seconds after leaving the feed preheater.
A feed preheater for an oxidative dehydrogenation (ODH) reactor, wherein the feed preheater is configured to heat a reactor feed to between about 150° C. and about 250° C. and flow the reactor feed into the ODH reactor within 15 seconds of the reactor feed reaching a maximum temperature.
An oxidative dehydrogenation (ODH) reactor, comprising:
- a feed preheater,
- wherein the feed preheater is configured to heat a reactor feed to between about 150° C. and about 250° C., and the feed preheater is configured to introduce the reactor feed into the ODH reactor within less than 15 seconds of the reactor feed reaching a maximum temperature.
