Dryer Membranes for Hydrocarbon Gas and Condensate Removal

You previously asked this question in a slightly different form. Shooting from the hip, I'm going to suggest that hydrocarbon molecules are much larger than water vapor molecules and that any membrane that allows hydrocarbons to pass through will also allow water to pass. Desiccant drying may be more effective because the pores in desiccants are sized to trap water exclusively. Refrigeration drying may also work. Remember that all dryers have a maximum flow rate. If you exceed that rate, the moisure content will rise.

Thanks Welderman. I hope your information can help. But I still don't get much answer from this infor. But anyway, appreciate your help.
