Liquefied petroleum gas (LPG ) is a clean-burning hydrocarbon gas in liquid form that may be Propane or Butane or a mixture of the two. It is a very versatile fuel, extensively used for space heating, cooking and catering, refrigeration, caravans, homes on metered estates, BBQs, industrial processes and heating, powering fork-lift trucks and vehicles, farming applications and, in its purest form, as an aerosol propellant.
LPG is produced as a by-product in oil refining and is also extracted from naturally-occurring sources. It exists as a gas at normal atmospheric pressure, taking liquid form only at very low temperatures or when put under further pressure.
Because LPG vapour is heavier than air, any leakage will sink to the ground and accumulate in low-lying areas and may be difficult to disperse, so LPG should never be stored or used in cellars or basements.
Propane can operate in low temperatures, whereas butane is suitable only for indoor or summer use. Like mains gas, LPG has no smell and so a strong "stenching" agent is added before delivery to help detection of any leaks.
Storing Bulk LPG and LPG Gas Bottles
Bulk LPG tanks or vessels store the gas outside homes and businesses and can be placed above-ground, or below-ground where space is at a premium or where aesthetic considerations hold sway, perhaps to protect a view or to a garden. LPG bottles or cylinders may be the best solution for those with a low level of usage or for applications such as mobile catering.
