<p>1. A process for the separation, at least in part, of at least one liquid constituent of a solution by means of the transfer of the same into the vapour phase, whereby the solution and the distillate are kept separated from each other by a porous dividing wall which can only be penetrated by the vaporous distillate and, if necessary, by any gases which are present, and with which the solution and the distillate are kept in contact, whereby the transfer into the vapour phase takes place on the solution side of the pores of the porous dividing wall, and the vaporous distillate diffuses through the pores to the distillate side, characterised in that while the separation process is taking place by means of pressure control and/or temperature control continuously at least in a part of the immediate surroundings of the porous dividing wall on the solution side the absolute temperature of the solution is set at 3% at the most below the boiling temperature which corresponds to the prevailing pressure, and in that on the distillate side neither a gas nor a separating gas is used.</p> |
