摘要：
This paper reviews various methods for the production of anhydrous ethanol by using different methods of water separation from alcohol. The analysis of energy efficiency and production costs is included. It is concluded that separation of ethanol and water can be accomplished with less energy than is now needed in conventional distillation processes. The state of development for these methods varies from laboratory investigation to commercially available processes. The processes investigated were categorized by type of separation depending on their ability to achieve varying degrees of ethanol/water separation. A summary of the projected energy requirements for these alternatives is shown. Recommendations for practice are given.
