    摘要： The invention is directed to a process for separating liquid mixtures, which includes passing a liquid stream of the liquid mixture over a membrane, the membrane being selective for at least one of a first compound and a second compound, whereby at least part of the liquid stream passes through the membrane leaving the other side of the membrane as a vapor, with the remainder of the liquid stream forming a retentate stream, and condensing the vapor on a condenser surface having a lower temperature than the liquid stream to give a distillate stream, the condenser surface forming a non-permeable heat conducting separation wall between the distillate stream and a cooling stream which cooling stream is a) a feed stream, or b) the retentate stream.

    摘要： The invention is directed to a process for separating liquid mixtures and an apparatus for separating liquid mixtures. The process of the invention comprises: passing a liquid stream of the liquid mixture over a permeable non-porous selective membrane, said membrane being selective for at least one of said first and second compounds, whereby at least part of the liquid stream passes through said membrane leaving the other side of said membrane as a vapor, with the remainder of the liquid stream forming a retentate stream, and condensing said vapor on a condenser surface having a lower temperature than the liquid stream to give a distillate stream, said condenser surface forming a non-permeable heat conducting separation wall between said distillate stream and a cooling stream which cooling stream is a) said feed stream, in case the feed stream has a sufficiently low temperature to serve as a suitable cooling medium for the condensation of the permeate vapor, or b) said retentate stream, in case the feed stream has such a high temperature that would make it unsuitable as a cooling medium for the condensation of the permeate vapor, so that heat can be transferred between the vapor and the cooling stream, wherein the distance between said membrane and said condenser surface is smaller than 10 mm, and wherein the vapor pressure of said distillate stream is lower than the vapor pressure of the compounds in the liquid stream for which the permeable non-porous selective membrane is selective, resulting in sufficient driving force for the separation to occur.
