A process for the mutual separation of volatile components in a mixture comprising at least two volatile components, comprising the steps of: (1) heating a starting liquid comprising at least two volatile components to vaporize the starting liquid and form a vapor mixture comprising the volatile component, (2) compressing the vapor mixture to cause a rise in the temperature and pressure thereof, (3) applying the compressed vapor mixture to a membrane having a selective permeability to separate the vapor mixture into a membrane-permeated fraction and a non membrane-permeated fraction, (4) indirectly placing at least one of the fractions in contact with the starting liquid of step (1) via a heat transferring wall to use the heat of the contacted fraction to vaporize the starting liquid, and (5) recovering one or both of the membrane-permeated fraction and non membrane-permeated fraction; and an apparatus for a mutual separation of volatile components in a mixture comprising at least two volatile components, comprising: (1) an evaporator having at least one heat exchanger into which at least one fraction separated by a membrane separator of (3) is introduced, a starting liquid feeding side, an evaporation residue discharging side, and an optional auxiliary heater; to generate a vapor mixture, (2) a compressor to compress the vapor mixture, and (3) a membrane separator comprising a member having a selective permeability to separate the compressed vapor mixture into a membrane-permeated faction and a non membrane-permeated fraction.
