Liquified Petroleum Gas (LPG)
(A Non-renewable Resource)


In 1910, under the direction of Dr. Walter Snelling, the U.S. Bureau of Mines investigated gasoline to see why it evaporated so fast and discovered that the evaporating gases were propane, butane, and other light hydrocarbons. Dr. Snelling built a still that could separate the gasoline into its liquid and gaseous components and sold his propane patent to Frank Phillips, the founder of Phillips Petroleum Company.

By 1912, propane gas was cooking food in the home. The first car powered by propane ran in 1913. By 1915 people were using propane in torches to cut through metal. LPG has been used as a transportation fuel, mainly in heavy trucks and forklift vehicles, around the world for more than 60 years.
