Liquefied Petroleum Gas is a Propane / Butane mixture liquefied under normal ambient temperature and moderate pressures. It is a safe, clean burning, reliable, high calroific value fuel. In addition to its use as a domestic fuel, it is also widely used in industries, where there is a requirement of low sulphur content fuel and fine temperature controls. LP Gas conforms to IS:4576-1999 specifications.
The Chemical composition of propane is C3H8 and butane is C4H10.
