Filter Material which Blocks Volatile Liquid, Passes Vapor

AI Thread Summary
The discussion centers on finding a filter material that allows only vapor to pass while blocking volatile liquids, specifically in scenarios like butane storage. The goal is to achieve a dry output regardless of the system's orientation, ensuring consistent vapor density at varying temperatures. Suggestions include using felt filter materials, which may allow vapor but can become saturated with liquid, and exploring flow-driven cyclone separators or vortex tubes for effective separation. The challenge remains in maintaining high output flow rates without significant vapor pressure loss across the filter. Overall, the conversation highlights the need for innovative solutions in vapor filtration technology.

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.
