How to remove Ethanethiol from household natural gas?
Just an idea: You can pass the gas through a bleach solution that can oxidize the thiol. I have no idea how effective this can be since the human smell is extremely sensitive to ethanethiol (to the scale of parts per billion). One possible set-up (very common in organic labs) is shown in this picture. The end Buchner flask should contain bleach and not HCl. The other conical is a safety measure in case you have suck back of the bleach solution.
