Activated charcoal will deodorize natural gas. It can be reactivated and used over and over again.
In the US we use a blend of sulfur compounds with an unpleasant odor.
In Europe they use an emetic odorant that induces a wretch response. Very effective at getting people away from the leak!
“Activated charcoal will deodorize natural gas. It can be reactivated and used over and over again.”
Makes sense, although reactivating means ‘heated’, I believe, so they’ll be consumin some gas for that. LOL.
Obviously this will also need to be done on a large scale.
