Abstract (en)
[origin: WO2018007509A1] A method for anti-surge protection of a compressor (7) under wet gas conditions is described. The compressor comprises a suction side (7S) and a delivery side (7D). An anti-surge system is arranged between the delivery side and the suction side of the compressor. The method comprises the following steps: calculating a surge limit line in a compression ratio vs. corrected power diagram; determining a compressor operating point in said compression ratio vs. corrected power diagram; detecting a distance between the operating point and the surge limit line; acting on the anti-surge system of the compressor if the distance is below a minimum safety distance.
