LPG Information & Advice
LPG (liquefied petroleum gas) is the generic name for commercial propane and butane. They are by-products of the refining of oil and natural gas with approximately 40% of all LPG coming from the refining of crude oil and 60% from the separation of gas products. It can be stored in gas cylinders/gas bottles or in bulk storage containers either above or below the ground. The pressurised cylinders are supplied up to about 80% full to allow for thermal expansion.
