  • Patent number: 4153546
    Abstract: A method and apparatus for separating a volatile solvent from a solution of the solvent and a relatively non-volatile solute. A temperature gradient is provided across solvent-absorbing and gas-entraining matrix material infiltrated with the solution, resulting in concentration of the solution near the hotter matrix surface and dilution of the solution near the cooler matrix surface. The process lends itself to the desalination of sea water and to applications which require the recovery of either solute or solvent.
