  • Patent number: 12203481
    Abstract: The invention relates to a compressor arrangement comprising a compressor (2) for compressing a process gas (13) from a suction region (21) towards a pressure region (22), a mechanical seal arrangement (3) for sealing against an atmosphere (6) on a shaft (5) of the compressor (2), wherein the mechanical seal arrangement comprises a mechanical seal (4) having a stationary slide ring (41) with a first sliding surface (41a) and a rotating slide ring (42) with a second sliding surface (42a), which define a sealing gap (42a) between the sliding surfaces (41a, 42a), and a barrier fluid supply (7) with a barrier fluid line (70) which extends from the pressure region (22) of the compressor (2) to the mechanical seal (4) and through which process gas is branched off from the pressure region, the stationary slide ring (41) having a through opening (8), which extends from a rear side (41b) of the stationary slide ring (41) to an orifice at the first sliding surface (41a) of the stationary slide ring to supply process ga
