Abstract (en)

[origin: DE19650910C1] The especially turbo-compressor has at least one rotor disc (2,3) with cover disc (4) positioned to the left in the direction of flow of the processing gas in the H2S non-critical range, and with a rotor disc with cover disc to the right in the H2S critical range. In the H2S non-critical range the disc diameter of at least one rotor disc increases with the same speed. The apparent yielding point of the rotor disc material is not dropped to the H2S critical threshold value. In the H2S critical range, at least one rotor disc (2) is positioned with a smaller disc diameter than that of the first rotor disc (3) and of material with a lower apparent yielding point.
