Filter Material which Blocks Volatile Liquid, Passes Vapor

  1. Jul 16, 2017 #1
    Hi, All.
    Given a scenario of a closed volume of volatile liquid and it's associated vapor above boiling point (ex. butane in a can at room temp.) which is dispensed through some tube or line:

    Is there some filtering medium capable of ensuring that only vapor may pass through the line, producing a completely (or nearly) "dry" output? Of course we could just pull the vapor from the top of the volume, but I would like a solution which would work in any orientation to ensure a consistent density of the output for a given temperature.

    I know this is possible by some means which have a very low molar flux rate, but I'm looking for higher output flow rates and no appreciable drop in vapor pressure across the filter at steady state.
    Thank you for your attention.
