The extent of temperature increase depends on several factors, including the initial temperature of the gas, the compression ratio, and the efficiency of the compression process. Higher compression ratios generally lead to more significant temperature increases. However, modern CNG filling stations are equipped with efficient compressors and heat management systems to minimize temperature rise and ensure the safety and integrity of the CNG during the filling process.
It is important to note that while CNG experiences a temperature increase during compression, it remains in a gaseous state and does not reach its ignition temperature. CNG has a much higher ignition temperature compared to gasoline or diesel, making it less prone to spontaneous combustion. Nevertheless, proper safety precautions and guidelines must be followed during CNG filling and handling to prevent potential hazards.
