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.
If your propane tank was at 40 percent and the propane company filled it to 80 percent, they added 40 percent of the tank's capacity in propane. The amount of gallons added would depend on the size of the tank, as propane tanks come in various sizes.
A faint odor around a propane fireplace could be due to gases like sulfur dioxide or mercaptan, added to propane for safety to detect leaks. It could also be from dust or debris burning off during initial use. Regular maintenance and ventilation can help reduce odors.
Green gas is just propane with some oil added to it. You can get a propane adaptor and use propane. Edit: The oil in question is silicone oil. Also, propane often has an additive called ethyl mercaptan, which causes its pungent smell. Green gas generally has a less strong smell, or none.
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.
Liquified propane sold as fuel in the US must be at least 90% pure propane; the rest is typically butane, propylene (5% maximum) and ethyl mercaptan, which is added to give it a noticeable and characteristic odor.

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.

Propane and butane. Some methanethiol (methyl mercaptan) is also added, giving a characteristic putrid smell to easily detect leaks.
Yes, Liquified Petroleum Gas is a Gas. It is a mixture of butane and propane. Also ethyl mercaptan is added to LPG to detect the gas leakage.
Odor masking agents can be added to help reduce the smell of ethyl mercaptan. Additionally, ensuring proper ventilation and containment of the gas can help control the odor. Regular maintenance of equipment and storage tanks can also prevent leaks and minimize odor issues.

When was mercaptan first added to gas in the U.S.?
Propane itself is totally odorless. But due to its extreme flammability, a tiny amount of a highly potent "odorant" gas (usually methyl mercaptan, which smells like rotten eggs) is added before sale for safety. It is not practical to remove the "odorant".
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.
