Summary:PROBLEM TO BE SOLVED: To provide a process for producing alcohol that achieves energy saving as a whole process and contributes to reducing the load on the rectification column and the side stripper.SOLUTION: In a process for producing high concentration alcohol by subjecting alcohol which has been concentrated by a rectification column to a membrane separation apparatus, by recycling the permeated liquid from the membrane separation apparatus back to the pretreatment process and/or the fermentation process, an energy saving as a whole process can be achieved.SELECTED DRAWING: Figure 1 【課題】プロセス全体として省エネルギーを達成し、精留塔及びサイドストリッパの負担軽減に寄与する、アルコールの製造方法を提供することを課題とする。【解決手段】精留塔による濃縮を経たアルコールを膜分離装置に供することで高濃度アルコールを製造するプロセスにおいて、膜分離装置からの透過液を前処理工程及び／又は発酵工程に戻すリサイクルにより、プロセス全体としての省エネルギーを達成できる。【選択図】図１
