Some of the most important natural gas facts are:-
1. Natural gas chiefly consists of methane (CH4), but also contains other hydrocarbons such as ethane, butane, propane and naphtha.
2. Natural gas is odourless, colourless and flammable. It is non-toxic and lighter than air; utility companies add the smell of rotten eggs a product called mercaptan to make leaks easier to detect.
3. There are over 15.2 million road vehicles worldwide that run on natural gas as a fuel. The gas is used in a compressed or liquefied state to power cars, buses, taxis, and trucks.
