ABSTRACT:
A process for producing a stream of oxidatively dehydrogenated C.sub.4 hydrocarbons with substantially all of the oxygen and inert noncondensable gases removed comprising absorbing the C.sub.4 hydrocarbons in an absorber oil in a first zone; stripping oxygen and inert noncondensable gases from the mixture of adsorber oil and C.sub.4 hydrocarbons in a second zone which is operated under conditions of temperature and pressure to maintain an aqueous phase in the second zone; and withdrawing (1) a predominately aqueous phase from the second zone, (2) an overhead of predominately all of the oxygen and inert noncondensable gases and a bottoms of adsorber oil and C.sub.4 hydrocarbon substantially free of oxygen and inert noncondensable gases.
