liquefied petroleum gas


liquefied petroleum gas
a gas liquefied by compression, consisting of flammable hydrocarbons, as propane and butane, obtained as a by-product from the refining of petroleum or from natural gas: used chiefly as a domestic fuel in rural areas, as an industrial and motor fuel, and in organic synthesis, esp. of synthetic rubber. Also called bottled gas, compressed petroleum gas, LPG, LP gas.
[1920-25]

also called  LP gas , or  LPG 

      any of several liquid mixtures of the volatile hydrocarbons propene, propane, butene, and butane. It was used as early as 1860 for a portable fuel source, and its production and consumption for both domestic and industrial use have expanded ever since. A typical commercial mixture may also contain ethane and ethylene as well as a volatile mercaptan, an odorant added as a safety precaution.

      LPG is recovered from “wet” natural gas (gas with condensable heavy petroleum compounds) by absorption. The recovered product has a low boiling point and must be distilled to remove the lighter fractions and then be treated to remove hydrogen sulfide, carbon dioxide, and water. The finished product is transported by pipeline and by specially built seagoing tankers. Transportation by truck, rail, and barge has also developed, particularly in the United States.

      LPG reaches the domestic consumer in cylinders under relatively low pressures. The largest part of the LPG produced is used in central heating systems and the next largest as raw material for chemical plants; LPG is also used as an engine fuel. Compare liquefied natural gas.
