Differences Between LNG and CNG
1 Answers
Differences between LNG and CNG: 1. Similarities and Differences: Both are natural gas with the same composition, differing only in their states of existence. 2. Meaning of CNG: CNG stands for Compressed Natural Gas, which is natural gas pressurized (over 3,600 pounds per square inch) and stored in containers in a gaseous state. 3. Meaning of LNG: LNG stands for Liquefied Natural Gas. LNG is produced by cooling gaseous natural gas at atmospheric pressure to -162°C, causing it to condense into a liquid. 4. Storage State and Containers: The storage states and containers differ. CNG is stored as a high-pressure gas in pressure vessels, typically at 20MPa, while LNG is stored in a cryogenic state in pressure vessels, usually at -160°C. The amount stored in pressure vessels of the same water volume differs under standard conditions.
