Natural gas distribution system

09 MAR, 2016

Natural gas can be found in the planet subsoil, being extracted through deep drilling till the natural gas deposits are reached. This  resource reaches us through a complex circuit of tubes and pipes that are appropriated  for it's transport from the extraction point to our houses and industries where it is used as fuel for different objectives like raw materials production, obtainment of other types of energy (electricity, for example) or heating. Some pipes can reach 60cm in diameter, which then, begin to subdivide into smaller and narrow pipes till delivery points and final consumers are reached.
Road transport in appropriate supply trucks is also used for natural gas transport. This type of transport is widely used to  restock gas storage units (UAG's). As in our homes, pastry shops or restaurants, for example, natural gas is used to heat ovens our stoves; in other companies it's used as machinery fuel; it's also used as heating source for spaces and water, and, is still used to run cars. Like electric energy, natural gas also goes through a counter which measures the amount of consumed gas. In rural areas, where there are no natural gas networks, propane gas (petroleum derived gas, processed in oil refineries) or gas cylinders are used. In Portugal, gas cylinders are still widely used.
Natural gas has advantages like being a cleaner fuel, since it releases fewer pollutants, hurting less the environment and it's cheaper than other alternatives like propane gas. When burning, the blue flame, not yellow, proves that the combustion releases less harmful substances like carbon monoxide and carbon dioxide. In automobiles, researchers are sure that natural gas it's a good fuel because it can produce 90% less pollutants than gasoline or diesel.
