LPG and Pollution

January 6th, 2011 No Comments »

LPG is albeit considered to be a clean fuel, there is some pollution which can be associated with the use of LPG. To understand this, let us take a look at the emission from Liquefied Petroleum Gas.

· LPG produces about 45% less carbon dioxide when compared to diesel. It also produces 33% less carbon dioxide when compared to petrol.

· LPG is also said to result in lesser hydrocarbon emissions. It is known to be lesser by almost 70% in comparison with diesel and 40% in comparison with petrol.

· Also, sealed LPG tanks are also known to eliminate spillage and it is known that refuelling LPG is a major source of hydrocarbon emission. To safeguard this, special valves meant for refuelling are suggested.

· When LPG is used in vehicles, they are known to produce lesser Nitrogen Oxide. When compared to petrol, it is lesser by almost 82%. The best comparison is said to come from diesel. LPG is considered to be 99% better in terms of emitting nitrogen dioxide.

· LPG results in 63% lesser carbon monoxide and this is also a great advantage.

· Again, going back to vehicular emission, LPG is considered favourable since it has a lower proportion of benzene as well as butadiene, when compared to those vehicles which run on gasoline.

· There are many green activists who argue that LPG cannot be termed as a green fuel since it results in the emission of carbon dioxide on burning.

Yet, when we compare LPG to other fuels, it is found to be truly better for the environment. It does not result in very high proportion of CO2 emissions. LPG also burns cleaner than diesel or petrol. The argument for or against LPG still continues. What is required to be remembered that LPG is also a non renewable source of energy and hence, the world over, people should always keep in mind that it needs to be used optimally and judiciously.
