1-3 ppm by volume
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.
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.
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.
Natural gas has no color and it also has no odour. The odour that you can smell that is associated with gas, is man-made so that humans know that there is a gas leak. Otherwise, it would simply kill you :)
Natural gas is naturally odorless, but in the 19th century, an odorant called mercaptan was added to it to help detect leaks. The practice began in the 1930s when safety concerns increased, and mercaptan's distinctive sulfur-like smell made it easier for people to notice gas leaks. This addition significantly improved safety in homes and industries using natural 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.
Mercaptan is a colorless gas with decaying or rotting, putrid or fetid smell.
Mercaptan is added to natural gas after it is processed to create an odorant that gives it a sulfur-like smell. This is done to help detect leaks and ensure safety by making it easier to identify gas leaks.
Natural gas is mainly methane with traces of mercaptan odorants deliberately added.
When was mercaptan first added to gas in the U.S.?
Yes it is. Natural gas has no smell of its own. Methyl mercaptan is used to add a bad smell to natural gas to warn you if a gas leak should occur.
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.
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. Methane, which is the primary ingredient of natural gas, is odorless and colorless. The gas company adds a chemical called mercaptan, which gives natural gas a recognizable sulfur or rotten egg odor.
