Abstract: Provided are a separation method for easily recovering normal butene from an olefin fraction including isobutene, isobutane, 1-butene, 2-butene, and normal butane, and a separation process system using the method. Since the separation method according to the present invention may easily convert 1-butene included in the olefin fraction to 2-butene, normal butene may be effectively separated and recovered by factional distillation and each recovered fraction may be easily refluxed even if the use of a reflux system using a refrigerant is reduced or excluded. Thus, economic efficiency may be improved and simultaneously, separation efficiency may be increased.

Abstract: The present invention relates to a method of recovering an absorption solvent in a butadiene production process through oxidative dehydrogenation, the method including: a) transferring a light gas discharged from an upper portion of an absorption tower to a wash column; and b) recovering the absorption solvent included in the light gas by a solvent circulating in the wash column. Since an absorption solvent may be prevented from being introduced into a reactor, or being discharged to an outside of a system, economic efficiency of a butadiene production process is improved.
