liquefied petroleum gas

Physics

Various petroleum gases, principally propane and butane, stored as a liquid under pressure. It is used as an engine fuel and has the advantage of causing very little cylinder-head deposits.

Liquefied natural gas (LNG) is a similar product and consists mainly of methane. However, it cannot be liquefied simply by pressure as it has a low critical temperature of 190 K and must therefore be cooled to below this temperature before it will liquefy. Once liquefied it has to be stored in well-insulated containers. It provides a convenient form in which to ship natural gas in bulk from oil wells or gas-only wells to users. It is also used as an engine fuel.

Chemical Engineering

A mixture of gaseous petroleum products normally stored and transported as liquid under pressure. The main constituents are propane and butane. LPG has an ignition temperature of 450°C and calorific value or 45.3 MJ kg⁻¹. It is largely used as an engine fuel and has a wide range of other industrial and domestic uses.
