        Natural Gas



                                                      It consists mainly of 95% methane with small quantities of
                                                      ethane and propane. India has vast reserves for natural
                                                      gas. In India, natural gas has been found in Tripura,
                                                      Rajasthan, and Maharashtra and in Krishna – Godavari
                                                      delta. When the natural gas is compressed by applying
        pressure, it is called Compressed Natural Gas.

        It is called a clean fuel because it burns without producing smoke and does not cause air pollution.

        Advantages of CNG

        1.     It is a good fuel as it produces lot of heat.
        2.     It burns with a smokeless flame and causes no air pollution.
        3.     It does not leave any residue after burning.
        4.     It can be directly used as a fuel. No need to add anything to it.
        5.     It can be supplied to homes and factories through network of pipes. So we can say it can be
               transportable.
        Uses
        1.     It is used as a domestic and industrial fuel.
        2.     It is used in Thermal Power Stations for generating electricity.
        3.     It is nowadays being used in vehicles.
        4.     It is used to manufacture fertilisers.
        5.     It can be used to manufacture petrochemicals.

        Petrochemicals


        Those chemicals that are obtained from petroleum and natural gas are called petrochemicals. For
        example: methyl alcohol, ethyl alcohol, formaldehyde, acetone, acetic acid, ethylene, benzene etc.

         Petrochemicals are very important because they are used to manufacture a wide range of useful
        materials such as: detergents, synthetic fibres, drugs, dyes etc.

        Petroleum is known as ‘black gold’ due to its great commercial importance.
