Differences Between Propane and Natural gas (methane)

  • LPG (propane) and natural gas (methane) have different chemical formulas: Methane is CH4. Propane is C3H8.
  • LPG-propane has a higher calorific value – energy content – than natural gas, with 93.2MJ/m3 vs 38.7MJ/m3.
  • For proper combustion, the air to gas ratio for LPG-propane gas is approximately 25:1 whilst the air to gas ratio for natural gas is a 10:1 ratio.
  • LPG (propane) is more dense than air, at a relative density of 1.5219:1 vs natural gas (methane) at 0.5537:1, natural gas is not heavier than air, it is lighter than air.
  • LPG (propane) can be compressed into a liquid and stored or transported in a cylinder or larger vessel.
  • LPG (propane) and natural gas appliances operate at different pressures.
  • Natural gas is also called mains gas, as it is delivered through gas mains or pipelines whilst LPG (propane) is bottled gas.
  • LPG (propane) can be easily processed into Simulated Natural Gas – SNG – and used as a substitute for natural gas. The same is not true in reverse.
