ABSTRACT:
A method of separating a liquid by pervaporation, which includes purifying a liquid to be treated by at least one pervaporation membrane module unit providing a supply line connected to the pervaporation membrane module unit and supplying the liquid to be treated to the membrane module unit, utilizing a withdrawing line for withdrawing the permeated fluid from the membrane module unit and a withdrawing line for withdrawing the non-permeated liquid, wherein the supply line is provided with a pressure pump for transporting the liquid and a heater, and providing the final withdrawing line for the non-permeated liquid with a pressure regulating valve.
At least one pervaporation membrane module unit includes a plurality of pervaporation membrane module units which are connected so that the non-permeated liquid of a first stage pervaporation membrane module unit is supplied to a second stage pervaporation membrane module unit, and the non-permeated liquid of an n-1 stage pervaporation membrane module unit is supplied to an n stage pervaporation membrane module unit, wherein the fluid permeating through the first stage pervaporation membrane module unit is steam. The steam permeated through the first stage pervaporation membrane module unit is condensed by a condenser with a refrigerant temperature of at least 0 degree Celsius and steam permeated through at least one of the second and subsequent stage pervaporation membrane module units is, after incorporating an organic solvent compatible with water, condensed by a condenser with a refrigerant temperature of at most 0 degree Celsius.
