Gas Liquid, called the LPG abbreviation, usually consists of two hydrocarbon compounds of propane and butane with the chemical formula C4H10, C3H8. The Bhutan itself contains two isobutane and butane compounds. LPG, which is commonly known in some parts of the world in the name of its major propane, is also the product of the processes of refining and producing natural gas and refining crude oil. LPG in the United States is composed mainly of 90% propane, 2.5% butane and heavy hydrocarbons, and a small amount of ethane and propylene. It was first produced in 1910 by Dr. Walter Snelling.
