Patent abstract
The object is to provide a method for producing an alcohol by applying a multiple-effect method to improve the energy efficiency of the whole process. The object is achieved by a method for producing an alcohol including a concentration step of introducing a water-alcohol mixed solution into a multiple-effect distillation column for concentrating the same; a condensation step of introducing a vapor recovered from the top of the distillation column into a condenser for condensing the same; and a separation step of introducing the water-alcohol mixed solution condensed in the condensation step in a liquid phase into a membrane separation apparatus for separating the water and alcohol in the mixed solution.
