What is LPG?
LPG is an environmentally friendly source of energy with a wide range of applications: domestic (heating, cooking, hot water production), industrial, agricultural, catering and automotive fuel. LPG is used in hundreds of applications by millions of users throughout the world. When LPG is burnt it produces the cleanest emissions of all oil-based products, with a low carbon dioxide output.
LP Gas (or LPG) stands for "Liquefied Petroleum Gas". The term is widely used to describe two prominent members of a family of light hydrocarbons called "Natural Gas Liquids" (NGLs): propane (C3H8) and butane (C4H10). The other two members of the NGLs family, ethane and condensates, have their own distinctive markets.
In a gaseous state at normal atmospheric pressure and temperature, LPG becomes a liquid at 15°C when the pressure is lowered to between 1.7 and 7.5 bar. This facilitates both storage and transportation. 1 liter liquid propane = 270 liters gaseous propane at 15°C. Propane starts vaporizing above -45°C and butane above -2°C (excluding its use in cold environments).
Industry experts predict that there will be enough LPG to satisfy anticipated demand for all uses in the foreseeable future.
LPG supply comes from two sources: 66% is automatically generated from gas fields as an associated gas when natural gas is extracted from the reservoir. A balance of 34% comes from crude oil refining as a by-product of the cracking process. With refinery capacity growing and strong grows in the production of Liquified Natural Gas (LNG) the production of LPG will increase substantially over the coming years.
