Abstract:
The shaft seal arrangement for a rotating turbomachine shaft having a rotation axis, comprises a rotor part and a stationary part. A dry gas seal is further provided, in combination with a cooling fluid volume arranged for receiving a cooling fluid and in heat exchange relationship with the dry gas seal. A venting arrangement collectively vents exhaust cooling fluid and dry sealing gas from the shaft seal arrangement.

Claim (Index 15):
A power conversion system comprising:\n a working fluid circuit having a high pressure side and a low pressure side and configured to flow a working fluid therethrough; a cooler arranged and configured to remove heat from the working fluid in the low pressure side of the working fluid circuit; a pump or compressor fluidly coupled to the working fluid circuit between the low pressure side and the high pressure side thereof, configured to rise the pressure of the working fluid in the working fluid circuit; a heat exchanger configured to circulate the working fluid in heat exchange relationship with a hot fluid, to vaporize the working fluid; a turboexpander fluidly coupled to the working fluid circuit and disposed between the high pressure side and the low pressure side thereof, configured to expand working fluid flowing therethrough and generating mechanical power therewith; wherein the turboexpander comprises: a casing; a shaft arranged for rotation in the casing; an impeller mounted on the shaft for rotation therewith; a shaft seal arrangement according to  claim 1 , for sealingly co-act with the shaft of the turboexpander.
