Zusammenfassung: | The compressor arrangement (1) comprises a main compressor (3) having a suction side (3S), a delivery side (3D), and at least one dry gas seal (7). The dry gas seal (7) is fluidly coupled to a sealing gas feed circuit (9) adapted to receive sealing gas from the delivery side (3D) of the main compressor (3) and feed the sealing gas to the at least one dry gas seal (7). An auxiliary compressor unit (25) is further provided, including a sealing gas inlet (29) fluidly coupled to the sealing gas feed circuit (9), and a sealing gas outlet (27) fluidly coupled to the sealing gas feed circuit (9) and adapted to booster the sealing gas pressure in the sealing gas feed circuit (9). The auxiliary compressor unit (25) is further adapted to receive a gas flow from the main compressor (3), for instance a primary vent from the dry gas seal (7) for recovery purposes. |
