PNG: An attractive alternative to LPG?

lpgThe Liquified Petroleum Gas (LPG) cylinder is quintessential in any Indian household and ‘gas agency connections’ are a priced possession. But the good ol’ cylinder now has competition: Piped Natural Gas (PNG). Is it really one of the most versatile fuels? And what are the benefits?

Let us start with the basics.

What is Natural Gas?

  • Primarily methane (CH4) with a small percentage of other higher hydrocarbons.
  • After extraction, the gas is purified and transported through a network of pipelines across the country.

Why is it cleaner?

The ratio of carbon to hydrogen is least in methane and therefore, it burns almost completely, making it the ‘cleaner fuel’.

Its applications

Domestic: Pipe gas is used for cooking as well as heating water through gas geysers.

Commercial: Hospitals, hotels, restaurants etc apply PNG in ovens, boilers, water geysers as well as for air conditioning.

Industrial: Many industries including garment units, export houses, pharmaceutical companies, metal treatment units, oil mills and printing units use PNG.

PNG is safer than LPG. Here is why:

  • PNG has a very narrow inflammability range. It has a very specific ‘air ratio’ requirement for ignition – the combustible mixture of natural gas and air does not ignite if the mixture is leaner than 5 per cent and richer than 15 per cent of the fuel. This makes PNG one of the safest fuels in the world.
  • Did you know natural gas is lighter than air? In case of a leak, therefore, it rises up and disperses into air (yes, ventilation is a must). LPG, on the other hand, is heavier and settles at the bottom, causing danger.
  • pngLPG expands 250 times on leakage. PNG installation inside a kitchen contains a very limited quantity of natural gas at a very low pressure. The supply can be switched off conveniently through an appliance valve (inside the kitchen) and an isolation valve (outside the premises).

Gas companies across India are now providing PNG straight to your house.

Some of them are GAIL, Indraprastha, HCG and MNGL. Now that you know about PNG and some of its benefits, do your own research and decide whether or not your family should consider using it!
