FAQ( Frequently Asked Questions) about LPG:
What is Liquefied Petroleum Gas (LPG) ?
Liquefied Petroleum Gas (LPG) is colourless, odourless liquid which readily evaporates into a gas. Normally odour is added to it to help detect leakage. This is a combination of Propane (chemical formula C3H8) and Butane (chemical formula C4H10), either stored separately or together as a mix.
Why is it called Liquefied Gas?
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. It’s generally distributed and transported into liquid form.
What is Propane?
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.
What is Butane?
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).
What are the advantages of LPG?
The advantages of LPG are as follows:
- 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.
- 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.
- 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.
- 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.
- 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.
