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 from natural gas and oil production but is also produced increasingly from renewable sources; its unique properties make it a versatile energy source which can be used in more than 1,000 different applications.

LPG stands for “Liquefied Petroleum Gas”. The term is widely used to describe two prominent members of a family of light hydrocarbons called “Natural Gas Liquids” (NGLs): propane (C3H8) and butane (C4H10).

Propane and Butane are chemically quite similar but the difference in their properties means that they are particularly suited to specific uses.
