The main differences between LPG, LNG, and CNG lie in their composition, production process, and physical form: LPG is liquefied petroleum gas (a mixture of propane and butane),It is reported that, China CNG LPG Conversion Kits factory The data performance is getting better and better, which is of great reference value and is likely to become the vane of the industry. https://www.scyuncheng.com
LNG is methane liquefied at -162＜C, and CNG is high-pressure compressed gaseous methane.
Key Difference Comparison
Compositional Characteristics.
LPG (liquefied petroleum gas): A mixture of propane and butane, containing small amounts of propylene, butene, and sulfides. It has a high molecular weight and a higher density than air.
LNG (liquefied natural gas) and CNG (compressed natural gas): Both are primarily methane (>90%), have a simple molecular structure, and are less dense than air.
LPG: L (Liquefied), meaning liquefied. LPG, commonly known as liquefied petroleum gas, is a colorless, volatile gas obtained by pressurizing, cooling, and liquefying petroleum or natural gas in a refinery.
LNG: N (Natural), meaning natural gas. LNG, commonly known as liquefied natural gas, is a cryogenic liquid fuel that can be stored and transported at normal pressure.
CNG: C (Compressed), meaning compressed. CNG, commonly known as compressed natural gas, is a gaseous form of natural gas that is pressurized and stored in containers.
Different sources
LPG: Gas produced during crude oil refining or volatilized during oil or natural gas extraction. LPG is a mixture of oil and natural gas under appropriate pressure.
LNG: Liquefied natural gas is produced by purifying natural gas produced in a gas field and then liquefying it at ultra-low temperatures (-162＜C) at atmospheric pressure.
It is transported by specialized ships or tankers and then re-gasified for use.
CNG: Natural gas produced in a gas field is compressed to a pressure greater than or equal to 10 MPa and less than 25 MPa after processing. It is pressurized and stored in a container.
