Abstract: The compressor system comprises a compressor having first compressor stage and a second compressor stage in a back-to-back arrangement. A first gas flow is provided at the suction side of the compressor. A seal arrangement is provided between the first compressor stage and the second compressor stage.

A side stream valve on the side stream line and a side stream controller are provided, for adjusting the flow of the second gas. An antisurge arrangement comprised of a bypass line and an antisurge valve is arranged at the first compressor stage for preventing surge of the first compressor stage. The side stream controller is configured for reducing the flow of the second gas when an alteration of the pressure ratio across the first compress stag is detected.
