Abstract
This invention provides an apparatus for separating condensable gas, which is provided with, as a membrane for separating condensable gas, an inorganic porous membrane which has a layer having a multiplicity of micropores communicating in the thickness direction of the membrane and having a pore radius, as determined by the nitrogen absorption method, of up to 50 .ANG., and preferably up to 20 .ANG., and which has an affinity for said condensable gas or is hydrophilic. This apparatus yields highly selective permeation of condensable gas, such as water vapor or organic gases.
