Welcome to LPGas.org, an online information and resource center for liquefied petroleum gas. Liquefied petroleum gas is a mixture of hydrocarbon gases used as a environmentally friendly fuel for cooking, heating homes, running forklifts, automotive engine fuel, aerosol propellants, ethylene cracker feedstock and many more important uses.
LP gases are members of the alkanes family of hydrocarbons. Most LP gases are commonly referred to as natural gas liquids in the U.S., and include ethane, propane, normal butane, isobutane and natural gasoline (also called pentanes and heavier).
Outside the United States, LP gas, or LPG as it is most commonly called, typically includes only the propane and butane components of the total gas liquids stream. Most countries use propane for cooking, heating and engine fuel, but many developing countries use mixtures of propane and butane, while a small handful use only butane as their primary LPG fuel of choice.
