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.
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).
Where is it used?
LPG has more than 1,000 applications: it is used in transportation, in commercial business, industry, farming, domestic heating and cooking, and for recreational purposes. The domestic sector is one of the most popular applications for LPG with almost 47% of the global demand for LPG coming from residential cooking and heating demands.
