LIQUEFIED PETROLEUM GAS

LIQUEFIED PETROLEUM GAS (LPG)

Liquefied Petroleum Gas (LPG), also referred to as simply propane or butane, are flammable mixtures of hydrocarbon gases used as fuel in heating appliances, cooking equipment, vehicles and petrochemical feedstock. When specifically used as a vehicle fuel it is often referred to as autogas. LPG is almost entirely derived from fossil fuel sources, being manufactured during the refining of petroleum (crude oil), or extracted from petroleum or “wet” natural gas streams as they emerge from the ground. 

LPG - GOST 20448-90
