Question

What is natural gas? How is it different from petroleum?

Accepted Answer

Natural gas is another fossil fuel that is found with petroleum in oil wells. However, some oil wells yield only natural gas. It mainly contains methane, which burns easily to produce heat. Methane is also a hydrocarbon. Transport and use of natural gas are made easy by compressing it under high pressure. In the compressed form, it is called Compressed Natural Gas or CNG. Traditionally, natural gas has been used as a fuel in industries and for the generation of electricity. It is now being used more and more in automobiles as a fuel.

Petroleum gas and natural gas are two common gaseous fuels. Petroleum gas is obtained as a by-product in the process of refining of petroleum. The main constituent of petroleum gas is butane although it also contains other gases, like ethane and propane. All these gases are hydrocarbons. Butane can be liquefied easily under high pressure. Therefore, it is stored and supplied in liquid form in cylinders. Cooking gas cylinders used at our homes contain liquefied petroleum gas or LPG, as it is commonly known.
