摘要： The rotor comprises a plurality of rotor segments arranged axially adjacent to one another. A tie rod extends through the rotor segments. Opposed first and second locking members arranged at the axial ends of the tie rod lock the rotor segments to one another and to the tie rod. At least one intermediate support member is arranged in an intermediate position between the two axial ends of the tie rod and between the tie rod and one of the rotor segments.

摘要： Compression train for a natural gas liquefaction process. The compression train includes a driver machine and only one centrifugal compressor machine driven in rotation by the driver machine; the compressor is configured to compress a refrigerant gas with a molecular weight less than 30 g/mol from a suction pressure to a discharge pressure; the ratio between discharge and suction pressures is higher than 10. A LNG plant including a compression train.
