Household natural gas is injected with a little bit of Ethanethiol to make it a distinctive odor for safety purposes.
But, if it is used to drive cars (*), its odor is sensible and it is annoying.
Is there a way to remove this from the household gas (which is mainly the mix of 90% methane and 10% ethane) on a home budget scale?
My first idea is to have some type of chemicaly which could be inserted into the empty bottle.
(*) In most countries, this can be done legally, although it has to follow relatively strict safety and tax regulations.
