Propane is one of the main ‘Liquefied Petroleum Gases’ (LPG). It is a light product that results from either distilling crude oil or by extracting it from the oil or gas streams found in the ground. Propane has considerable heating power and is typically stored outdoors, even in cold temperatures, because it easily liquefies and remains a gas in temperatures as low as –42 ºC. It has a variety of uses, including household heating and hot water, and in various farming and industrial services. It can also be used to fuel vehicles.
