While natural gas occurs in nature as a mixture of methane and other gases, propane is actually a byproduct of both petroleum refining and natural gas processing.
Different Energy Content. There are also two main differences in the way that LPG (Propane) and natural gas (Methane) are burnt. The first difference is in the energy content. LPG has a higher calorific value, or energy content, so less gas is required to produce the same amount of heat.utogas (Propane/Butane mix). Autogas that is sold at petrol stations can be either just Propane or a Propane/Butane mix. Not only is running an LPG car economical, but Autogas is also cleaner burning fuel than petrol, so engine life is actually extended and greenhouse gas emissions reduced.
