Can you buy natural gas in canisters?

Answer 1

The short answer is no. Here is why.

Gas delivered in a canister must be in the liquid state. These gases have a critical temperature, above which it can not be liquefied. The critical temperature is a physical property of the gas. It is fixed. If the temperature of the gas is above the critical temperature, it is not a liquid.

Natural gas is mainly methane, with some ethane and a trace of higher hydrocarbons. The critical temperature of methane is -82.7 C. The critical temperature of ethane is 32.2 C. Ambient temperatures at which the canisters are stored can easily be higher than these critical temperatures.

The critical temperature of propane is 97 C. Propane is the lightest hydrocarbon that can be delivered as a liquid at ambient temperatures.

Answer 2

Never seen it and would not expect to, the under lying factor being the small amount that can be stored in a cheap and light small canister relative to the equally good fuels propane/butane. Propane and butane can be liquefied at ambient temperatures and moderate pressures and have a much higher density than gaseous methane/ethane (natural gas) albeit under some pressure.

Answer 3

For it to be liquefied, it would have to be refrigerated to minus 161 deg Celsius, which is impossible unless you have specialised refrigeration equipment.

Can also be liquefied by pressurising, but you would have to pressurise it to 350 something bar, which is way too much.

Answer 4

Not to sure, but I'm willing to fart in a bean tin for you, if that helps! LOL

Answer 5

you can get it for free by using an old coke can and farting into it

Answer 6

no. Just propane and butane
