Abstract
The invention relates to a process for the simultaneous exchange of heat and matter through a porous wall. A relatively hot gaseous mixture of two constituents passes through an exchange compartment by flowing along the first surface of a porous wall and is progressively cooled, which causes the condensation of a fraction of said mixture. This fraction is vaporized on the second surface of the wall in contact with a relatively cold gas. This process is useful for the fractionation of a mixture of two constituents of a gas, for example, of a mixture of pentane and heptane.
