Liquefied petroleum gas (also called LPG, GPL, LP Gas, autogas, or liquid propane gas) is a flammable mixture of hydrocarbon gases used as a fuel in heating appliances and vehicles. It is increasingly used as an aerosol propellant and a refrigerant, replacingchlorofluorocarbons in an effort to reduce damage to the ozone layer.Varieties of LPG bought and sold include mixes that are primarily propane (C3H8), primarily butane (C4H*0) and, most commonly, mixes including both propane and butane, depending on the season — in winter more propane, in summer more butane. Propylene and butylenes are usually also present in small concentration. A powerful odorant, ethanethiol, is added so that leaks can be detected easily. The international standard is EN **9.
