What is the difference between CNG and cooking gas?
Cooking gas is LPG.
CNG is compressed natural gas – methane.
LPG is liquefied petroleum gas – propane.
There are many similarities between LPG and CNG, as well as some major differences…
What are the Differences between LPG vs CNG (Natural Gas)?
• LPG has a higher energy content than CNG, with 25MJ/L versus 9MJ/L, respectively.
• Storage pressure of LPG is less than 2 MPa whilst CNG is 20 – 25 MPa.
• For proper combustion, LPG requires an air to gas ratio of approximately 25:1 whilst natural gas requires a 10:1 ratio.
• LPG and natural gas appliances operate at different pressures – 2.75 kPa vs 1.1 kPa, correspondingly.
• LPG (propane) is denser than air at a relative density of 1.5219:1 vs natural gas (methane) at 0.5537:1, which is lighter than air.
• CNG cylinders have a tare weight approximately 3x heavier than comparable capacity LPG cylinders.
• LPG can be compressed into a liquid, increasing its energy density.
• LPG (propane) and natural gas (methane) have different chemical formulas: Methane is CH4. • Propane is C3H8.
