How Is Liquefied Petroleum Gas Produced?
LPG has three origins: approximately 60% is recovered during the extraction of natural gas and oil from the earth, the remaining 40% is produced during the refining of crude oil or made from renewable and waste materials. LPG is thus a naturally occurring by-product. In the past, LPG was destroyed through venting or flaring (i.e. the burning off of unwanted gas), wasting the full potential of this exceptional energy source.
