Abstract
The present invention relates to a separation method and a separation process system for easily recovering ethanol from an ethanol oligomerization reactant containing unreacted ethanol. A separation method according to the present invention may easily reflux ethylene while reducing or excluding the use of a reflux system which uses an expensive cooling medium, and the like, and thus may improve the economics while increasing separation efficiency.
