a method of separating and recovering components of a mixture having a gap in the range of miscibility and including organic compounds and water in a pervaporization process with the aid of membranes . the mixture is first separated into an organically loaded water phase and a water - saturated organic phase . subsequently , the organically loaded water phase and the water - saturated organic phase are separately subjected to parallel , different pervaporization processes , resulting in retentates as water on the one hand and organic liquid on the other hand . the permeates that result during the pervaporization processes are subsequently returned to the mixture that is to be separated .
