Mercaptan is the substance that causes natural gas to smell bad. It is typically added to gas before the gas is shipped or piped, so that any leaks can be instantly detected.
When was mercaptan first added to gas in the U.S.?
The odor added to natural gas is called mercaptan. It was first added to natural gas in the 1930s by a chemist named Dr. Walter Snelling.
The distinct smell of natural gas is due to the addition of a chemical called mercaptan, which is added to it before distribution for safety reasons. Mercaptan has a strong, sulfurous odor that makes it easier to detect a gas leak.
Mercaptan is a colorless gas with decaying or rotting, putrid or fetid smell.
A chemical called mercaptan is added to natural gas to give it a distinct, sulfur-like smell. This odorant is added as a safety measure to help detect gas leaks since natural gas is naturally odorless.

Natural gas is mainly methane with traces of mercaptan odorants deliberately added.

Pure natural gas is colourless and odourless. This means if there is a leak people will not be able to detect it until it builds up enough to become explosive. For this reason a chemical called Mercaptan is added to the gas to make is smell. Mercaptan is harmless, non-toxic and has a strong "rotten egg" smell.
The amount of mercaptan in natural gas can vary, but typically it is added at levels around 1-30 parts per million (ppm) to give natural gas its characteristic sulfur-like odor. This odorant is added for safety reasons to help detect potential gas leaks.

None. Ethyl mercaptan is not used to odorize natural gas. The normal odorant used for natural gas is tertiary butyl mercaptan, which is present at a concentration of approximately 0.5 pound/million standard cubic feet of gas.
1 ppm of mercaptan in 1 million standard cubic feet (mscf) of natural gas would be equivalent to 1 pound of mercaptan.
On average, about 3.5 to 4 gallons of liquid mercaptan is added to 1,000 cubic feet (1mcf) of natural gas to provide a detectable odor. This is necessary as natural gas is odorless and the addition of mercaptan helps to ensure safety by making gas leaks easily detectable.
Well, honey, mercaptan was first used in natural gas back in the 1930s. It was added to give natural gas that lovely rotten egg smell so folks can detect leaks and avoid blowing up their homes. So, next time you catch a whiff of that stinky scent, thank mercaptan for saving your bacon.
