Centrifugal Compressors

Centrifugal compressors increase the kinetic energy of the gas with a high-speed impeller and then convert this energy into increased pressure in a divergent outlet passage called the diffuser. Centrifugal compressors are particularly suited for compressing large volumes of gas to moderate pressures.Centrifugal compressor means any machine for raising the pressure of a natural gas by drawing in low pressure natural gas and discharging significantly higher pressure natural gas by means of mechanical rotating vanes or impellers.Centrifugal compressors are members of a class of technologies called dynamic compressors, or turbocompres- sors. Axial compressors are also part of this class of turbo machines. Axial and centrifugal compressors draw their names from the primary direction in which the flow moves within the compressor.
