LPG (Liquefied Petroleum Gas)

---

LPG (Liquefied Petroleum Gas) is predominantly propane and butanes, either segregated or in various ratios and mixtures of each product. LPG is a by-product of crude oil production (Associated Gas) and a by-product of natural gas production (Non Associated Gas). It is also a by-product of the refinery process, transported mainly in pressurised vessels.

Associated and Non Associated LPG or NGL’s (Natural Gas Liquids) are shipped via pipeline in large quantities where possible, for example in the US, and via refrigerated VLGC’s (Very Large Gas Carriers) from, for example, the US Gulf Coast to Japan. As well as being a fundamental building block in the petrochemical process, LPG it also a convenient fuel used globally for domestic purposes; in the northern hemisphere, LPG is used for home heating, while in Africa it is used as a cooking gas. In some markets, LPG is also used as a fuel for cars (known as Autogas).
