    • 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.
    • 一种生产氧化脱氢的C4烃的方法,其中基本上除去所有的氧气和惰性不可冷凝气体,包括吸收第一区域中的吸收剂油中的C4烃; 在温度和压力条件下操作的第二区中从吸附器油和C4烃的混合物中汽提氧气和惰性不可冷凝气体,以将水相保持在第二区域; (2)主要是所有氧气和惰性不可冷凝气体的塔顶馏出物和基本上不含氧气和惰性不可冷凝气体的吸附剂油和C4烃的塔底物。
