Mercury, and try to not poison yourself. Perfluorocarbons may also
exclude it. Anything Lewis basic (incuding aromatic sextets) or
polarizable will dissolve it nicely.

Try H2SO4 (and BE VERY CAREFUL!!!)

Try using concentrate sulforic acid H2SO4. In fact, H2SO4 is used in
laboratory to generate HCl by dropping H2SO4 into saturate NaCl
aqueous solution.
H2SO4 + 2NaCl --> Na2SO4 + HCl(g)

This may be a stupid suggestion, but here goes. HCl is soluble in water only
to about 38% concentration (if memory serves me correctly). If your problem
can allow for it, why don't you bubble HCl vapor through concentrated
hydrochloric acid?
If this suggestion is no good, stick with the nonpolar solvents. Dry
aliphatic hydrocarbons (hexane, heptane, octane, etc.) should meet your
needs. However, be forewarned. These liquids are very flammable.

are very chemically unreactive and would remove for example entrained
oil Norpar and Isopar are some tradenames available through chemical
supply houses. if trying to remove non volatile water soluble material
could use conc HCL itself, or bubble HCl through water until it is
saturated and won't absorb any more. Most important to be careful in
either case and use proper equipment and procedures for handling strong
acids!

If the idea here is to produce a purified HCl stream, or if the continued
purity of the stram is important, one might also want to ask "How soluble
in HCl are these liquids."

Paraffinic oils and solvents (hexane, heptane, etc.) should work. Make
sure they are truly olefin- and aromatic-free or you will observe
development of a brown color over time. The best way to do this is to stir
the solvent or oil over conc. H2SO4 overnight, decant, and repeat with
fresh H2SO4 until the H2SO4 layer no longer turns brown after stirring
overnight.
Why do you say that paraffin oil didn't work?

How's about concentrated hydrochloric acid? The gas should
simply pass straight through...
