What is the difference between PNG and CNG gas?

The only difference between CNG and PNG is the form of delivery. CNG comes out of natural gas bottles whilst PNG comes out of a pipe. Both are refined natural gas with methane being the primary constituent.

Which gas is used in PNG?

LPG is Liquefied Petroleum Gas and PNG is Piped Natural Gas. LPG is supplied in liquid form just as the name suggests in cylinders whereas PNG is supplied through a pipeline. LPG is used as a fuel in heating appliances and vehicles, where as PNG is used for cooking (gas stoves) and heating water (gas geysers).

What is CNG & PNG?

Natural gas as its name indicates is a Gaseous fuel, consisting of 87-92% of Methane with a small percentage of other higher hydrocarbons. PNG, CNG & LNG are different forms of Natural gas under varied temperature & pressure.

Which is better CNG or LPG?

CNG is Compressed Natural Gas, which is mainly methane compressed at a pressure of 200 to 248 bars. LPG is Liquefied Petroleum Gas, a mixture of propane and butane liquefied at 15 °C and a pressure of 1.7 – 7.5 bar. … CNG is cheaper and cleaner, but LPG has a higher calorific value.

Which is better LPG or PNG?

“PNG is much cheaper than LPG. While a 14.2-kg subsidised domestic LPG cylinder costs ₹538, the same quantity of PNG, which is calculated based on standard cubic metres (SCM), comes at a price of Rs 375,” GAIL officials said. One kg is equivalent to 1.164 SCM.

What is PNG Gas full form?

Piped Natural gas (PNG) is used for Domestic, Commercial and Industrial Consumption. PNG has several distinctions to its credit-of being a pollution free fuel, economical and safer fuel being few of them.

Which is safer LPG or PNG?

Piped natural gas, though not risky as compared to LPG, is also flammable.


Safety Since it is lighter than air, in case of leakage it gets dispersed fast. Heavier than air, tends to settles at the floor level during leakage. Highly combustible, causes extensive loss to life and property

Why CNG is not used for cooking?

Also, CNG has been accepted as a clean fuel but due to its volatility in nature they have not been used as cooking gas, since it has high auto-ignition temperature (540°C) and a narrow range of flammability of 5 to 15%.

How do you make CNG gas?

CNG is made by compressing natural gas, which is mainly composed of methane (CH4), to less than 1% of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of 20–25 MPa (2,900–3,600 psi), usually in cylindrical or spherical shapes.

Which gas is present in CNG?

CNG (Compressed Natural Gas) is a mixture of hydrocarbons consisting of approximately 80 to 90 percent methane in gaseous form. Because of its low energy density, it is compressed to pressure of 200 to 250 Kg/cm2 (to enhance the vehicle on-board storage in a cylinder), hence the name Compressed Natural Gas.

Why is CNG preferred over LPG?

Answer. CNG preferred over lpg because it produce greenhouse gases upon combustion, it is a more environmentally clean alternative to other fossil fuels like gasoline or LPG.

Can LPG be filled in CNG kit?

LPG cannot be used in a CNG kit, its like putting diesel in a petrol car. … Moreover, if a car has the CNG option there is no point in running it on LPG. CNG is way more economical than the LPG, and whenever you need more power, you always have the option at hand of running it on petrol.

What is the life of CNG car?

Usually, a CNG cylinder can last anywhere between 15-20 years.

Are gas pipelines safe?

According to the U.S. Department of Transportation, pipelines are the safest, most reliable and cost effective means of transporting energy products, such as natural gas, over long distances.

Which gas is used in IGL?

It is gaseous fuel and is a mixture of hydrocarbons mainly Methane. For use in Automobiles as fuel, it is compressed to a pressure of 200-250 Kg/cm² to enhance the vehicle on-board storage capacity.

Is piped gas safer than cylinder?

A user from Yeshwanthapura says piped gas is not risky at all since the gas supplied is at a pressure that is hundred times lower than LPG. Besides, there is no question of waiting for the cylinder delivery boy, delayed booking or safety issues associated with cylinder openings.
