Liquefied petroleum gas is one of the most common and an alternative fuels used in the world today. Liquefied petroleum gas is also called as LPG, LP Gas, or Auto gas. The gas is a mixture of hydrocarbon gases used as a fuel for various purposes. This is mainly used in heating appliances and vehicles and is replacing chlorofluorocarbons as an aerosol propellant. It is also used as a refrigerant mainly to reduce damage to the ozone layer.
You will find many places where it isn’t an alternative fuel at all. LP gas is a mainstay for cooking and heating in some areas of India and rural areas of the United States and the other parts of the world. LPG is also used as alternate for petroleum and Diesel. The main reason behind this being the soaring in the prices of the oil, LPG has emerged as much preferred choice. LPG is a fossil fuel and can be refined from oil and natural gas.
The refining is very similar to that of gasoline is refined from crude oil. LPG is basically a hydrocarbon with propane and butane as main constituent. LPG is a by-product of natural gas processing. It is the product that comes from crude oil refining when carried with the smaller amounts of propylene and butylenes. LPG is largely propane and thus the characteristics of propane are sometimes taken as a close approximation to those of LPG. When the natural gas is produced, it constitutes of methane and some other light hydrocarbons which are easily separated in a gas processing plant. There are many natural gas liquid components that are recovered during processing.
These components mainly include ethane, propane and butane and few other heavier hydrocarbons. The other gases that are being produced as refining by product are propane and butane along with other gases that rearrange or break down the molecular structure and obtain more desirable petroleum compounds.
