What is a characteristic of a CNG compressor?

A CNG compressor is primarily designed to increase the pressure of compressed natural gas. As natural gas is compressed, its volume decreases, enabling it to be stored or transported more efficiently. The process of compression raises the pressure of the gas, making it denser and allowing larger quantities to be stored in smaller volumes, which is critical for applications such as fueling vehicles.

While cooling the gas may occur as a secondary effect due to the compression process, and various filters may separate impurities in the gas before it reaches the compressor, those functions are not the primary purpose of a CNG compressor. Additionally, a CNG compressor does not burn excess gas; instead, it focuses on compressing and increasing the pressure of the gas for storage or distribution. This emphasis on pressure enhancement makes it essential for the safe and efficient utilization of natural gas as a fuel source.
