Beschreibung
Zusammenfassung:	A charge gas compression train for ethylene including a first compressor including a first group of compression stages, a second group of compression stages, and a third group of compression stages. The first group of compression stages includes an outlet configured to be connected to a first intercooler inlet. The second group of compression stages includes a second compressor inlet configured to be connected to a first intercooler outlet, and a second compressor outlet configured to be connected to a second intercooler inlet. The third group of compression stages includes a third compressor inlet configured to be connected to a second intercooler outlet. The first, the second, and the third group of compression stages are integrated in a first common casing and operate at the same rotation speed. The first compressor includes a plurality of unshrouded and shrouded impellers, where an unshrouded impeller is positioned upstream to a shrouded impeller.
