LPG Full Form is Liquefied Petroleum Gas. LPG is a byproduct of crude oil. It can also be derived during the process of CNG extraction. There are basically two kinds of LPG; (1) Butane, which is used as a fuel for heaters, lighters, hair spray, paints, and camping stoves, (2) Propane, which is used for automobile fuels.
The advantage or uniqueness of LPG is that it can easily convert into liquid state, as it is mildly compressed. This property enables large quantities of gas to be stored in smaller space. The reverse is also true that if it is allowed to escape or if the gas leaks, the liquid quickly changes into gas and evaporates. Hence it is safe to use for a cooking range where there is also a need for increased quantity.
