WebMar 5, 2024 · Compressed Natural Gas (CNG) applications start at 5 lbs. and move up to 4600 lbs. Pipeline applications, on the other hand, use very low compression ratios between 1.05 and 1.2 in a single-stage unit. No matter what the application is, calculating the overall compression ratio is the first step in the design process. WebWhen natural gas and biomethane are liquefied, the volume of the gas compresses to one six-hundredths of what it would be at atmospheric pressure. This allows the gas to be transported and stored much easier and thus more economically. Therefore, gas liquefaction is typically used instead of gas compression when: when the largest possible ...
