Currently, environmental protection has been significantly interested , traditional fuels such as coal, gasoline, and diesel are gradually being replaced with cleaner, more environmentally friendly, commonly known as Liquefied Petroleum Gas (LPG), Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG), . So, what are the differences between CNG, LNG, and LPG? The following information will help you understand and distinguish between CNG, LNG, and LPG.

1. About definition
1.1. What is CNG?
CNG (Compressed Natural Gas) is natural gas extracted from natural gas fields or associated gas produced during oil extraction. It is transported through pipelines to gas processing plants to remove impurities and then sent to compression stations, where it is compressed to high pressures (200-250 barg) and stored in specialized tanks. The main component of CNG is CH4 - methane, which makes up around 85-95% of its composition, remaining are ethane, propane, and other substances. CNG is colorless and odorless.

1.2. What is LNG?
LNG (Liquefied Natural Gas) is natural gas that has been liquefied through deep cooling to approximately -162oC (-260oF) after being processed to remove impurities. The main component of LNG is methane (CH4), which accounts for about 95% of its composition, remaining are ethane, propane, and other substances. LNG is colorless and odorless. The volume of natural gas in its liquid state is about 600 times smaller than its volume in its gaseous state, making it very convenient for long-distance storage and transportation to the point of consumption.

1.3. What is LPG? LPG (Liquefied Petroleum Gas) is a liquefied mixture of light hydrocarbons, with propane and butane as its main components. It is liquefied for convenient storage and transportation. LPG is produced from natural gas streams extracted from oil wells or through crude oil refining processes. LPG is colorless and odorless.
