LPG is the abbreviation of liquefied petroleum gas, which means liquefied petroleum gas.
LNG is the abbreviation of liquefied natural gas, which means liquefied natural gas;
The main components of liquefied petroleum gas are propane and butane.
The boiling point of propane is -42 degrees Celsius, so it is a particularly useful portable fuel. This means that even if the temperature is very low, propane can be vaporized immediately after it is released from the high-pressure container. Therefore, it is a clean fuel and does not require many devices to evaporate it and mix it with air. A simple nozzle is enough.
Butane has a boiling point of about -0.6 degrees Celsius and will not evaporate at a very low temperature. Therefore, the use of butane is limited, and it needs to be mixed with propane and cannot be used alone.
The main component of liquefied natural gas is methane, with a small amount of ethane and propane.
Liquefied natural gas is colorless, tasteless, non-toxic and non-corrosive. It can be liquefied at normal pressure and around-162℃, and its volume is about 1/625 of the gaseous volume.
