Frequently Asked Questions (FAQs) on PNG
Yes. Natural Gas is a user friendly, economic, safer and non-polluting petro fuel. It is theoretically 23% cheaper than domestic LPG. It does not require booking of refill, chasing up delivery, hassles of facing delivery boys, storage space etc. There are no chances of pilferage. PNG is safer as compared to LPG due to its light weight nature. In the event of leakage, it dissipates immediately in the air. The supply of NG can be easily controlled by various safety checks/valves installed in the system.
Yes, supply is absolutely regular. The pipeline distribution network is based on an on- line supply system that consists of safety valves and regulators that control and monitor the gas supply and pressure, and assist in identifying system leaks. Thus, an un- interrupted supply at a constant pressure is assured.
PNG works on a cooking appliance just like LPG does. It is not required to change the LPG appliances, with minor modifications in LPG appliances, done by trained GNGPL technician can be converted to PNG.
The LPG connections can be surrendered to the respective oil company and security deposit refund obtained.
A domestic PNG connection includes laying of pipe line network up to appliance along with necessary fittings, pressure regulator, meter and conversion of LPG appliance to PNG.
Domestic PNG has multiple uses in the residential houses. It can be used for cooking, space heating, air-conditioning, power generation.
PNG pipeline inside house is not allowed to be concealed as per safety norms. Pipeline will run on the surface of the wall. At places where pipeline needs to be crossing a wall, a small hole to suit the dia of pipeline/sleeve shall be made in the wall. There will be minimum cutting of the wall. Floor, tiles in the kitchen will not be cut for concealing the pipeline. Laying of pipe line will be done after discussion with the owner at time of laying. Owner will be required to provide most economical and shortest route for pipeline up to the kitchen.
GNGPL gets the source natural gas through the main transportation pipe and receives it at city gate station and steel grid network is developed. To regularize the pressure of the gas, District Regulatory System is installed. Further a network of MDPE, is developed to reach to different societies and building etc. The regulator, followed by raiser with GI pipeline is installed which is connected to a meter. A copper pipe and further rubber tubing is done to get PNG reach to stoves.
Submit Registration form along with Proof of Identity (Any one of the following: PAN Card/ Passport/Voter Id Card/ Driving License/Ration Card/ Aadhar Card) and Proof of ownership of the establishment (Copy of Sale Deed Agreement/Rent Agreement/Electricity bill/BSNL Telephone bill/Society Certificate etc.)
Customer may kindly take note of the provision of The Liquefied Petroleum Gas (Regulation of Supply and Distribution) order, 2000 as amended vide notification dated December 16,2013 which has mentioned of supply of LPG under Public Distribution System (PDS) ie. subsidized to a PNG domestic consumer as 'prohibited activity. However, with LPG control order letter dated 09th January 2014 you can retain one LPG connection and the Government oil companies shall provide the refill at the non-subsidized rate.
Frequently Asked Questions (FAQs) on CNG
CNG stands for Compressed Natural Gas. It is a gaseous fuel and is a mixture of hydrocarbons, mainly methane in the range of 95%. Due to its low density, it is compressed to a pressure of 200 bar to enhance the vehicle on-board storage capacity.
Yes, it is safe. The properties of CNG make it a safe fuel. It is lighter than air, and hence in case of leakage it disperses into the atmosphere rapidly. Its high auto-ignition temperature of 540 degrees centigrade as against petrol’s 360 degrees centigrade makes it even more safe fuel. CNG also has a narrow inflammability range of 5% to 15%, making it much safer than other fuels.
ll spark-ignited engines can be converted to CNG, for which a specially designed conversion kit is required for the conversion process. The kit consists of a cylinder to be fixed in the boot of the car and other equipment’s to allow gas flow into the engine.
Yes, after conversion to CNG the vehicle can run on petrol whenever desired simply by flicking a switch on the dashboard.
The cost of converting a vehicle to CNG depends on the type of your vehicle and CNG kit. Presently, the cost of conversion ranges between Rs. 25,000 to Rs. 50,000 (approximately).
CNG cylinders are manufactured from a special steel alloy and are seamless in construction. Their compact size allows them to easily fit into a small car. An empty CNG cylinder with a 50 litre-water-carrying capacity weighs 48 kg (approximately), and has a length of 835 mm and a diameter of 316 mm. The 50 litre capacity cylinder is the one most regularly used in CNG kits but cylinders with 45 litre, 55 litre, 60 litre and 65 litre capacity are used as well.
A cylinder with a 50 litre water-carrying capacity is capable of carrying approximately 9 kg of CNG. This is equivalent to 12.5 litres of petrol and will allow a run of about 150-160 kms. for a medium sized 1300 CC car. An electronic fuel gauge fitted on the dashboard which is part of the conversion kit indicates the quantity of CNG left in the cylinder.
CNG cylinders are designed and built in such a way so as to withstand high pressure. The maximum pressure in a CNG cylinder is up to 200 bar. CNG cylinders are safe as they are manufactured as per specific requirements and tested before use, in accordance with international specifications and standards, and are duly approved by the Chief Controller of Explosives (CCoE). Moreover, they are provided with a pressure relief device (PRD) that consists of a fusible plug and a burst disc that ruptures in case of extremely high pressure and temperature.
Yes, the fuel bill on the basis of average running of vehicle reduces substantially when compared to other conventional fuels. Price of CNG is lesser than other fuels and also it enhances the mileage of your vehicle, making it the most economical fuel.
Owing to CNG's distinct features, it does not contaminate or dilute crankcase oil, giving a new lease of life to the engine. The absence of any lead content in CNG helps avoid lead fouling of plugs, thereby enhancing plug life. As CNG enters the engine in the form of a gas (and not as a spray or mist like other fuels), no carbon is generated during the combustion of CNG reducing the chances of wear and tear.
Yes, it is. As CNG mainly consists of methane which is the simplest hydrocarbon, it is a much cleaner and efficient fuel. The use of CNG significantly reduces harmful exhaust gas emissions like carbon monoxide, nitrogen dioxide and sulphur dioxide which causes harmful diseases like cancer, asthma etc. CNG also helps in reducing the effects of global warming.
Cylinders used for storing gas are designed with very high safety factor in accordance with global standards. These cylinders are tested and certified for usage by statutory authorities and each cylinder is defined with an expiry date of usage after which they are to be tested again for safe use. These cylinders have been designed to take impact of collision in case of accidents. However, as per Gas Cylinder Rules, 1981, the cylinder should undergo hydro-stretch testing every 3 years to check pressure tolerance.
CNG kit is safe and simple. It gives years of trouble free operation. It doesn’t require frequent servicing. Just as for all other fuels, it is advised to have routine services. An authorized person should be consulted for service. As per Gas Cylinder Rules, 1981, the cylinder should undergo hydro-stretch testing every 3 years to check pressure tolerance.
No. Dual fuel option in case of a diesel vehicle is not available as CNG requires Spark Ignition (SI) engine whereas Diesel engine has compressed ignition. However multiple CNG cylinders installed in CNG powered commercial vehicles gives ample time to refill CNG before it is completely drained off.
Factory fitted CNG vehicles have the same payload that of a diesel vehicle, however in case of retro fitment payload of the vehicle is reduced to the tune of cylinders weight only.
