Q. What are the benefits of PNG over LPG?





Being lighter than air escapes to atmosphere in case of leakage. On leakage, LPG expands 250 times, which is not the case with PNG. 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. This narrow in flammability range makes PNG one of the safest fuels in the world.

Many instances of cylinder blast causing fatal accidents and damaging human life & property.


No possibility of theft. A unique feature is that the user gets to pay only after consumption of gas. The domestic consumer pays the PNG bill only once in every two months.

Chances of short weight cylinder delivery.


No possibility of adulteration

Adulteration possible

Quantity loss

Only pay for gas entirely used as per meter. No loss. In case the consumption is less than 4 scm in a bi-monthly billing cycle, consumer is liable to pay minimum Rs. 100 towards PNG Bill.
