LPG stands for Liquified Petroleum Gas. The composition of LPG is Hydrogen and Carbon, also known as Hydrocarbons. Specifically, LPG consists of a combination of Propane (C3H8 ), and Butane ( C4H10).
LPG can be obtained as a co-product of refining of crude oil at refineries, or extracted from streams of natural gas from oil and gas fields. Propane and Butane are both gases in ambient conditions but can be liquified under modest pressure and temperature conditions. Furthermore, LPG can safely and easily be stored at room temperature.
