LPG or liquefied petroleum gas, is the generic name for propane (C3H8) and butane (C4H10) gas. Both of them are a mixture of hydrocarbon gases that people use as a fuel in heating appliances and vehicles. They can be transported/stored separately or as a mixture.These gases are called as liquefied petroleum gas because they liquefy under moderate pressure and readily vaporize upon release of pressure.oth of them are a mixture of hydrocarbon gases that people use as a fuel in heating appliances and vehicles.
