摘要
The invention relates to a method for separating substance mixtures in liquid and/or vapour form by pervaporation and/or vapour permeation, according to which the membrane (3) is configured as a dimensionally stable hollow body which is open to one side or is positioned on a porous hollow body which is open to one side and serves as support (1). The hollow body is positioned in a heatable container (4) which contains the substance mixture (5) to be separated. A concentration gradient for the substance to be separated (permeate) is set between the substance mixture to be separated and the inner chamber (7) of the hollow body. The concentration gradient moves the permeate (8) through the membrane (3) and into the inner chamber (7) of the hollow body. The permeate (8) is then evacuated from the inner chamber (7) of the hollow body and the substance mixture (retentate) stripped of the permeate (8) is removed from the container (4). The flow rate in the container is between 0.1 and 0.3 cm/s. The invention further relates to a device for carrying out the above method.
