Retail Gas : Advantages
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. The PNG distribution network will be connected to cross-country pipelines like Hazira-Vijaipur-Jagdishpur pipeline, which is connected with the natural gas production sources.
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.
Safety:
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: At present PNG has been priced at 10% cheaper than the Domestic LPG. In addition to this the customer can save by avoiding delivery of underweight cylinders.
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. Its combustion results in virtually no atmospheric emissions of sulphur-dioxide, and far lower emissions of carbon monoxide, reactive hydrocarbons and carbon dioxide, than combustion of other fossil fuels. In fact, when natural gas burns completely, it gives out carbon dioxide and water vapour

CNG:
CNG is non-toxic and free from Lead and Benzene, and emits less pollutants
Natural gas is free from adulteration and theft. Due to the absence of any lead or benzene content in CNG, the lead fouling of spark plugs is eliminated.
CNG-powered vehicles have less maintenance cost as compared with other fuel-powered vehicles. CNG fuel systems are sealed, which will prevent any spill or evaporation losses.
Increased life of oils. Another practical advantage observed is the increased life of lubricating oils, as CNG does not contaminate and dilute the crankcase oil.
CNG mixes easily and evenly in air being a gaseous fuel.
High auto-ignition temperature. CNG is less likely to auto-ignite on hot surfaces, since it has a high auto-ignition temperature (540 degrees centigrade) and a narrow range (5%-15%) of inflammability.
