What is the function of compressors in CNG systems?

In Compressed Natural Gas (CNG) systems, compressors play a crucial role by increasing the pressure of natural gas, which is essential for its conversion to CNG. When natural gas is compressed, its volume is significantly reduced, making it more practical for storage and transportation. This compression allows natural gas to be stored in high-pressure tanks, where it can be utilized efficiently for various applications, including fueling vehicles.

The process involves drawing the natural gas from a lower-pressure source and mechanically compressing it, which raises the gas's pressure and reduces its volume. This enables the safe and efficient storage of natural gas as CNG, which is particularly important for applications like automotive fuel, where space and weight considerations are significant.

Other functions such as cooling the gas, filtering impurities, or monitoring gas flow are related to different processes within the CNG infrastructure but do not represent the primary purpose of compressors in these systems. These additional functions may complement the overall operation but do not focus directly on the key role that compressors serve in enabling the transition from natural gas to CNG.
