Liquefied Petroleum Gas (LPG)
Definition - What does Liquefied Petroleum Gas (LPG) mean?
Liquefied Petroleum Gas, abbreviated as LPG is a highly combustible compressed gas obtained from refining crude oil in a refinery. Since it is the lightest of all the refinery cuts or refinery yields produced, it is obtained immediately during the first distillation process. It is used as a domestic fuel for cooking purposes or raw material for chemical synthesis process.
Petropedia explains Liquefied Petroleum Gas (LPG)
Liquefied petroleum gas is a mixture of propane and butane and is denser than air. Thus, if LPG leaks from the compressed LPG cylinders it becomes a very serious matter for safety reasons as it can explode with just a small spark. LPG is primarily used as a domestic fuel in developing nations for heating and cooking purposes as well as running internal combustion engines (Gasoline-driven engines). However, the safety of LPG driven vehicles still remains a concern. Apart from this LPG, is also used as a refrigerant and an aerosol propellant and has been replacing CFC’s so that damage to the ozone layer can be mitigated.
When LPG is burnt, it burns completely without leaving any soot and its sulfur emission is also less. Thus, it is considered to be a cleaner fuel. When compared with natural gas as fuel, LPG has low calorific value as well as causes little amount of extra emissions than natural gas. Also, natural gas being lighter than air, it tends to rise up if leaked, making it safe when compared to LPG as LPG settles on the floor or low spots and thus it have more chances of catching fire.
