LPG stands for Liquefied Petroleum Gas. The term is widely used to describe both Propane and Butane. At normal temperature and pressure, LPG is gaseous. It changes to a liquid when subjected to modest pressure or cooling which means it can be easily stored in bulk tanks or portable cylinders. In liquid form, the tank pressure is about twice the pressure in a normal truck tyre which means it is very safe when handled properly.
LPG is a by product of two large energy industries. It is used to be turned off and wasted till its value was recognised as a unique low carbon fuel thus making it a very important global energy source that is perfect for a wide range of applications.
