Answer:
Difference between CNG and LPG
CNG LPG
Its primary use is as an alternative for fuel in automobiles. It has various uses such as heating and cooking in homes. LPG also has industrial and agricultural uses.
The primary component in CNG is methane. The primary component in LPG is propane and butane.
It produces relatively lower quantities of greenhouse gases (in comparison with LPG). It produces relatively large amounts of carbon dioxide, a greenhouse gas.
It is relatively safe as it disperses rapidly into the air. It is highly flammable as it is much heavier than air.
The primary source of obtaining CNG is from oil wells, bed methane wells, coal wells and even natural gas wells. The main source of obtaining LPG is from the process of extracting natural gas from reservoirs.
