Knowra Liquefied petroleum gas Liquefied petroleum gas Liquefied petroleum gas (LPG) is a flammable fuel composed chiefly of propane, butane, or both. It is stored as a pressurized liquid and vaporizes for use as a gas.
Vapor pressure : The pressure exerted by a vapor in equilibrium with its liquid at a given temperature. LPG containers retain liquid because the fuel’s vapor creates pressure inside them.
Propane : A three-carbon alkane gas used as a fuel and as a chemical feedstock. Propane is a major LPG component, especially in colder climates and outdoor applications.
Autogas : Liquefied petroleum gas used as fuel in internal-combustion vehicles. Autogas is LPG adapted for vehicle storage, delivery, and engine use.
Liquefied natural gas : Natural gas, primarily methane, cooled into a liquid for storage and transport. LNG is cryogenically liquefied methane, unlike LPG’s pressurized propane and butane.
Liquefied petroleum gas safety : Practices and engineering controls for preventing LPG leaks, fires, explosions, and exposure. LPG’s pressurized flammability makes cylinder handling, ventilation, and leak response essential.
Boiling point : The temperature at which a liquid’s vapor pressure equals the surrounding pressure. LPG boils and vaporizes when pressure or temperature allows its boiling point to be reached.
Butane : A four-carbon alkane with structural isomers, used as a fuel and chemical feedstock. Butane is blended into LPG and contributes fuel value and storage characteristics.
Camping stove : A portable stove designed to burn fuel for cooking outdoors. Small LPG cylinders provide portable cooking fuel for camping stoves.
Compressed natural gas : Natural gas stored as a gas under high pressure, commonly for transport fuel. CNG remains gaseous in its tank, whereas LPG is stored mainly as liquid.
Gas explosion : A rapid combustion event caused by ignited flammable gas mixed with air. An LPG leak can form an ignitable mixture that explodes if confined and sparked.
