PNG has several distinctions over other fuels:
Uninterrupted supply: PNG network offers continuous and adequate supply of Natural Gas, doing away with the problems of storing gas in cylinders.
Unmatched convenience: No hassles of booking LPG cylinder and no long wait for its delivery. No tedious routine of checking LPG refill cylinder for any suspected leakage or it being underweight during delivery. The user is spared the inconvenience of connecting and disconnecting the LPG cylinder, and saves space occupied by LPG cylinders.
Narrow inflammability range makes PNG one of the safest fuels. The combustible mixture of natural gas and air does not ignite if the mixture is leaner than 5% and richer than 15% of the air-fuel ratio required for ignition.
Natural gas is lighter than air. Therefore, in case of a leak, it quickly disperses into air with adequate ventilation.
PNG is supplied through pipelines at a very low pressure, so it is a safer system as the quantity of Natural Gas is very small inside the premises.
In case of fire the PNG supply can be cut off through valves provided in the pipelines inside and outside of the kitchen.
The system design is tamper proof, thus, ensuring total safety. In case of any tampering or in an emergency, the system automatically shuts down, thereby avoiding any accident.
Since natural gas is odourless, ethyl mercaptan (a chemical that has a sulphur-like odour) is added before distribution, to give it a distinct odour. This is similar to the odour of LPG and serves as a safety device by allowing it to be detected in the atmosphere in cases of leak.
Economical: Natural Gas is economically more viable compared to other fuels in the same sector.
Versatility: Natural gas is being used predominantly as a versatile fuel in many major cities catering to domestic and commercial applications, as fuel for cooking, heating water, space heating, air conditioning, etc.
Environment Friendly: Natural gas is one of the cleanest burning fossil fuels, and helps improve the quality of air and water, especially when used in place of other more polluting energy sources. When natural gas burns completely, it gives out carbon dioxide and water vapou.
CNG has several distinctions over other fuels:
No impurities, No Sulphur (S), No lead (Pb)
Very low levels of polluting gaseous emissions without smell and dust
Molecular structure compactness prevents the reactive processes which lead to the formation of Ozone (O3) in the troposphere.
Lighter than air - in case of leak no dangerous puddles
Unlikely to ignite due to:
Lowest injury and death rate per vehicle mile
CNG cylinders structurally most sound and have passed every severe tests
Very high antiknock power (more than 120 ON) allows greater performance compared to petrol one.
Does not require refining plant or additive adding and can be used immediately after its extraction.
It has no evaporation leaks and spills of fuel, both during refueling and feeding of the car.
Its combustion produces a very low quantity of carbon deposits (permits a longer life of lubricant oil, spark plug, piston drum, valves & other components)
How Air pollutants will affect you:
Lead: A toxic metal present in normal petrol and in the air as fine particles can affect the central nervous system, cause renal damage and hypertension. Children are three times more at risk than adults.
SPM: Particle of dust and carbon coated with toxic gases, all emanating from factory and automobile exhaust, coat the lungs, causing respiratory infections, persistent cough, throat irritation, and aggravate asthma.
Carbon Dioxide: Colourless and odourless, carbon dioxide is emitted from petrol-run vehicles, mostly two and three wheelers. It reduces the ability of blood to carry oxygen and exacerbates heart disorders.
Sulphur Dioxide: A colourless gas, a part diesel exhaust and factory emissions, affects the upper respiratory tract and causes bronchial problems.
Benzene: A part of unleaded petrol and is emitted from catalytic converters. A known carcinogen linked to lung cancer and leukaemia.
Oxides of Nitrogen: Formed during fuel combustion in motor vehicles and power stations. Convert nitrogen dioxide which leads to bronchial infections, clods, headaches, eye irritation.
Polycyclic Aromatic Hydrocarbons: Unburnt from diesel engines cause drowsiness, eye irritation, cough and is suspected to be cancer-causing.
