Abstract
A multi-stage integrally geared compressor includes a first process stage, a second process stage and a gearbox for coupling the two process stages to each other at different rotational speeds. The gearbox further couples a compressor drive shaft to the two process stages at a further rotational speed, which is different from the rotational speeds of the process stages.
