The primary components of liquefied petroleum gas (LPG) are propane, butane, propylene, butylene, and isobutane. LPG is a highly flammable mixture of these hydrocarbon gases which is widely used as a fuel in household cooking applications.
LPG is produced during oil refining or is extracted during the natural gas production process. If you release LPG, gas is emitted. In order to transport it, LPG needs to be placed under modest pressure to form a liquid. It can then be stored and transported in LPG cylinders.
LPG is not natural gas but is derived from natural gas processing and has higher energy content. It is portable and available everywhere. although there are major differences between the two, LPG and Natural Gas are used for thousands of applications in homes and businesses.
