The flow of a vapor through a porous ceramic membrane is investigated. The membrane consists of several layers and is asymmetric with respect to the flow direction. The flow process is modeled accounting for capillary condensation, for the capillary pressure at liquid menisci, and for the temperature difference between the upstream and the downstream side of the membrane due to the Joule-Thomson effect, which induces a transfer of heat in downstream direction. Condensation may occur in various parts of the membrane. Condensation has a large influence on the mass flux through the membrane. The mass flux in one flow direction through the membrane may be a few times larger than the mass flux in the other flow direction.
