  • Surge control for centrifugal compressors
    Patent number: 4203701
    Abstract: A surge control system for a centrifugal compressor having a recycle line between the discharge and suction, modulates flow in the line in accordance with molecular weight and temperature of the gas being compressed, pressure drop across the inlet orifice, and pressure drop across and power input to the compressor. The system is based on the standard relation that the product of the gas constant times the pressure drop across the inlet orifice divided by the suction temperature equals the pressure drop across the compressor.
