Liquefied Petroleum Gas (LPG) is a portable, clean and efficient energy source which is readily available to consumers around the world. LPG is primarily obtained as a by-product of the oil-refining process. Its unique properties make it a versatile energy source which can be used in hundreds of different applications.
As its boiling point LPG is below room temperature, and so will evaporate quickly at normal temperatures and pressures. It is thus supplied in pressurised steel vessels, normally called LPG cylinders.
