Abstract
Systems and methods for dehydrating a mixture of organic liquid and water are disclosed. A mixture of the organic liquid and water is fed to a membrane. The mixture is then subjected to process conditions sufficient to cause pervaporation. A permeate comprising a higher weight percentage of water than the weight percentage of water in the mixture is recovered. A retentate comprising a higher weight percentage of organic liquid than the weight percentage of the organic liquid in the mixture is also recovered.
