Gas Distribution As we mentioned before, Carbon and hydrogen are the constituents of methane gas. This gas has the chemical formula of CH4. Here we should mention that there is no relevancy between natural gas and “gasoline” which is some times called in brief as “gas”. As seen in oil, natural gas is found under ground and Ocean floors. Drilling for natural gas is similar to what done for oil. Bringing a large volume of natural gas to the consuming points needs large pipes. Some of pipes are two feet wide. Generating electricity is highly dependant to this fuel. Many other industries as well as small ones such as bakeries depend on natural gas. Pipelines in different sizes are used for its distribution up to its particular consumption points. Bringing natural gas to a building or house, needs a meter to measure volume of consumption for charging purposes. In a home, it is used for cooking, heating water and keeping the house warm. In rural areas and wherever places, not having access to pipelining networks, other forms of fuel or liquefied gas in safe cylinders is used. Propane, in liquefied form must be kept under low pressure and be made in very low temperatures. Natural gas can be used in cars, trucks and other form of transportations. For such a purpose special safe tanks must be used. As the burning of pure natural gas produce carbon dioxide and water vapor without any toxic by products, it is considered a safe and ideal fuel in many industries. But existence of some impurities, including sulphides may cause pollution, much less than conventional, more complex gasoline. In a comparison, natural gas is ninety percent cleaner. So in a general consensus, many people prefer a natural gas fueled car in future.
