ABSTRACT:
More efficient mixing, more complete hydrogen consumption, and more thorough cooling of a dehydrogenation zone effluent is obtained by educting a portion of the dehydrogenation effluent from the reaction and externally cooling the withdrawn effluent in a heat exchanger and externally admixing the withdrawn effluent with an oxygen-containing stream. Eduction of the hydrogenation effluent by the oxygen-containing stream provides the necessary pressure drop for passing the dehydrogenation effluent through the heat exchanger and then admixing the effluent and oxygen-containing stream.
