20 views

CNG (Compressed Natural Gas) and LNG (Liquefied Natural Gas) are not the same. CNG is stored under high pressure in gaseous form, whereas LNG is cooled to -162°C and stored in liquid form. CNG is often used for vehicles, while LNG is used for transporting natural gas over long distances and for heavy-duty transport.

FAQs & Answers

  1. What is the main difference between CNG and LNG? CNG is Compressed Natural Gas stored at high pressure in gaseous form, while LNG is Liquefied Natural Gas cooled to -162°C and stored as a liquid.
  2. What are the common uses of CNG and LNG? CNG is commonly used to fuel vehicles, whereas LNG is primarily used for transporting natural gas over long distances and powering heavy-duty transport.
  3. Why is LNG cooled to very low temperatures? LNG is cooled to -162°C to liquefy the natural gas, reducing its volume for easier and more efficient transportation and storage.
