The advantages of LPG are as follows
1. Because if its relatively fewer components, it is easy to achieve the correct fuel to air mix ratio that allows the complete combustion of the product. This gives LPG its clean burning characteristics.
2. Both Propane and Butane are easily liquefied and stored in pressure containers. These properties make the fuel highly portable, and hence, can be easily transported in cylinders or tanks to end-users.
3. LPG is a good substitute for petrol in spark ignition engines. Its clean burning properties, in a properly tuned engine, give reduced exhaust emissions, extended lubricant and spark plug life.
4. As a replacement for aerosol propellants and refrigerants, LPG provides alternatives to fluorocarbons which are known to cause deterioration of the earth’s ozone layer.
5. The clean burning properties and portability of LPG provide a substitute for indigenous fuels such as wood, coal, and other organic matter. This provides a solution to de-forestation and the reduction of particulate matter in the atmosphere (haze), caused by burning the indigenous fuels.
Butane and Propane are both alkanes. This means that they are unreactive. Therefore, Butane and Propane are used in combination in fuels as their low level of reactivity increases the safety of the fuel. Also, Butane and Propane are by-products obtained from refining petroleum. In addition, both Propane and Butane can be liquefied easily thereby making them ideal for a fuel.
Butane is a hydrocarbon that is present natural gas and can be obtained when petroleum is refined. Commercial Butane predominantly consists of hydrocarbons containing four carbon atoms, mainly n- and iso – butanes (C4H10).
Propane is a gaseous alkane that can be obtained when petroleum is refined. Propane is Colourless. The chemical symbol of Propane is CH1,CH2,CH3. Propane can be liquefied when it is compressed and cooled.
It is called LPG because Both Propane & Butane can be liquefied at normal temperature by application of a moderate pressure increase or at normal pressure by application of cooling using refrigeration.
LPG or Liquefied Petroleum Gas is a general description of Propane (The chemical Formula for Propane is C3H8) and Butane (The Chemical Formula for Butane is C4H10), either stored separately or together as a mix.
