Abstract
A geared multishaft turbocompressor with impellers arranged in series in terms of flow, which are fastened to two or more pinion shafts, which are arranged in parallel to one another and are driven directly via a central gear or indirectly via pinion shafts on the circumference of the central gear. Two or more compressor impellers are arranged in the same direction of flow in the area of the high-pressure stages III and IV on a pinion shaft. An intercooler is arranged between an intermediate outlet housing and an intermediate inlet nozzle. In stage III, the gas enters the impeller through the inlet nozzle, and it leaves the compressor via an intermediate outlet housing. After intercooling, the gas again enters stage IV via the inlet nozzle, and it leaves this stage via the outlet housing after flowing through the second impeller. An analogous arrangement of the stages Ia, IIa, IIIa is used in the radial expander, with opposite direction of the gas flow.
