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.
Ethyl mercaptan is not an oil.
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.
When produced propane and butane is odorless and colorless. Ethyl mercaptan is the odorant added to propane and butane in the processing and refining process to provide a detectable odor. Under certain conditions the odorant in propane may oxidize and lose its destictive odor. This odor fade can occur in new steel containers when first placed into service and in older steel containers that have been left open to the atmosphere. Air, water, or rust in a propane tank or cylinder can also reduce propane odor concentration. Ethyl mercaptan is toxic although the amount added to propane is non-threatening.
Gas companies add a smelly gas, typically ethyl mercaptan, to odorless methane for safety reasons. This distinctive smell makes it easier to detect gas leaks, helping to prevent potential fires or explosions in case of a leak.
I lived in Denver City, Texas in July 1994 and a pit filled with sulfur which contain mercaptan, as it is found in the production of oil and gas. This pit full of sulfur was the results of Shell Oil Company processing Hydrogen Sulfide Gas into sulfur. this process also contained some Mercaptans (Sulfur plus methane gas molecule). In July 1994 this pit caught on fire with no known cause. The pit was an open pit and if you came close to it you could smell the mercaptans. The official cause was that lightning but if you have ever been around liquid mercaptans you would that it can catch on fire with ease. stallingssd@cox.net Ethyl mercaptan will burn quite readily. It wouldn't be a very good additive for gas if it didn't. It will also autoignite. The temperature required is relatively high. Autoignition is the temperature at which a material will burn when heated to and is typically tested by taking a drop of a material and dropping it into a vessel at a known temperature. If it ignites when it hits the bottom of the vessel, the autoignition temperature has been exceeded. Most sulfur doesn't contain a lot more hydrogen sulfide than they do mercaptan.
Ethyl mercaptan is not an oil.
Tetrahydrothiophene and amyl mercaptan are examples; but ethyl mercaptan is preferred now.
Ethyl mercaptan is commonly used as an odorant in industries such as natural gas, petroleum, and chemical manufacturing. It is added to these substances to give them a distinct smell, making it easier to detect leaks or spills. Additionally, ethyl mercaptan is used in the production of pesticides, pharmaceuticals, and as a chemical intermediate in various processes.

Ethyl mercaptan
This substance is ethyl mercaptan.

A compound called mercaptan is added to LPG to detect its leakage. Mercaptan is a sulfur-containing compound that gives LPG a distinctive smell, making it easier to detect any leaks as it has a strong odor.
ethanithiol ( IUPAC) ethyl mercaptan is added in lpg to detect leakage by the odour.
Because it has a very strong odor; it's easily detected even in minute quantities. And it has a vapor pressure relatively close (really relatively) to propane, for which it is used as an odorant.
That is not a very clear question. Are you asking if the materials left in a propane tank could be toxic if you use the tank for water? If so, then the answer is yes, but you are not going to be having a lot of ethyl mercaptan. An old propane tank can contain a significant amount of hydrocarbons, usually in the gasoline and diesel boiling point range.
