unsure if you're post concerning Propane is tongue-in-cheek but just in case any are taking it seriously, the use of Mol Sieves will soon knock out any unwanted elements.
More concerning would be NORM's or mercury, as the former is a real headache (Naturally Occurring Radioactive Material) and the latter means a lot of plant set-up to knock it out properly...not just silica removal.
I haven't seen anything to indicate this play is contaminant rich.
