Liquefied Petroleum Gas (LPG) is propane or butane, or a mixture of the two. These fuel gases are obtained from natural gas, or as a byproduct from the refining of oil.

LPG has a vast array of uses in home, farming, industry and commercial services.

There are two types of LPG; Propane and Butane, which have similar properties but different applications. They are not interchangeable due to the different operating pressures and burner settings required. Valves and fittings are also different to avoid confusion or accidental use of the wrong type of Gas.

PROPANE has a lower boiling point down to -45 C than BUTANE who has the lower vapour pressure at equivalent temperatures and is suitable for interior use only.so Propane will continue to convert from a liquid to a gas even in very cold conditions. When stored as a liquid in a tank, it exerts a greater pressure than butane at the same temperature. So Propane is most suitable for exterior storage and use. Its ability to operate in low temperatures makes it suitable as a fuel for many applications.

The chemical composition of Propane is C3H8 and Butane, C4H10. Because the make-up of each gas contains traces of other gases.
