Liquid separator instead of molecular sieve

I should put this here for reference:

A bubble column for vapor phase butane:
Run the filtered liquid butane from a tank, down into a heated floor-level assembly that is filled with pure DI water… I considered adding acid to salt the amine, but see *NO Acid… below
Something like a “Hochstrom” SS table-top Buchner on a heating pad, with a fine sintered SS disc as the membrane support, a hydrophobic 0.1μm pore PTFE membrane, and maybe a 36" tall column holding 30" of water over it, which is capped over the headspace with another hydrophobic PTFE membrane “Hochstrom” assembly, piped over to a bottom-up, high-capacity drying column… bottom ⅓rd filled with desiccant grade activated alumina beads, topped with good ol’ 13X.

Alternatively, you could sparge butane gas into water with a dip tube and diffuser, then run the vapor up, out, and through a 4Å molecular sieve bead drying column… Same concept, maybe easier to implement.

*NO Acid… Salt buildup would be horrible for such a thing! Even if it took a long time, it would eventually clog the membrane.
