Does anyone have a filter or method for removing BTEX from butane and propane? There are numerous water filters for benzene removal but I have not come across any methods for removal from gases or pressurized liquids. I tried a Donaldson clean LPG filter but after testing realized it filters down to half a micron and benzene is much much smaller than half a micron.

Willing to try any ideas as well.

Thank you,
