    摘要： A wet-gas centrifugal compressor is disclosed. The compressor comprises a compressor casing and at least one impeller arranged in the compressor casing for rotation around a rotation axis. A stationary diffuser is arranged in the compressor casing and extends around the impeller. The diffuser has a curved end portion with a radially inner curved wall and a radially outer curved wall. A plurality of dry-gas extraction holes is provided, ending at a plurality of respective inlet ports arranged around the rotation axis and on the inner curved wall of the curved end portion of the diffuser. Each dry-gas extraction hole extends from the respective inlet port towards the rotation axis and is inclined over a radial direction, such that each dry-gas extraction hole is oriented in a counter-flow direction with respect to a direction of the gas flow in the curved end portion of the diffuser.
