The invention concerns a high-pressure multi-stage centrifugal compressor containing at least two compressor elements (1, 4, 5) which are arranged in series as compressor stages, and at least two electric motors (3, 7) to drive these compressor elements (1, 4, 5), characterised in that, apart from at least one compressor element (1) forming a low-pressure stage and which is driven by an electric motor (3), it contains at least two compressor elements (4, 5) forming high-pressure stages and which are arranged in series and are driven by one and the same second electric motor (7).
L'invention concerne un compresseur centrifuge à multi-étages haute pression, comportant au moins deux éléments compresseurs (1, 4, 5), montés en série sous la forme d'étages de compresseur, et au moins deux moteurs électriques (3, 7) servant à entraîner les éléments compresseurs (1, 4, 5). Ce compresseur centrifuge est caractérisé en ce que, à l'exception d'au moins un élément compresseur (1) formant un étage basse pression et entraîné par un moteur électrique (3), il comporte au moins deux éléments compresseurs (4, 5) formant des étages haute pression, montés en série et entraînés par un seul et même deuxième moteur électrique (7).
