LPG COMPOSITION & CHARACTERISTIC
     
 
  LPG is a mixture of gas, mainly propane (C3H8 ) and butane (C4H10 ).  LPG is commonly used as a fuel in homes for cooking and heating and as a transportation fuel.  It is normally created as a by-product of petroleum refining and from the production of Natural Gas.  LPG is non-toxic and flammable gas which is heavier than air.
