Beschreibung
Zusammenfassung:	A method for sealing an oxygen-rich process gas within a compressor or expander, including providing a rotor component having a rotating element and providing a stator component having a stationary element. Introducing a seal gas into the first sealing zone and introducing a buffer gas into the second sealing zone. Wherein at least a portion of the rotating element includes the teeth of a first labyrinth seal. Wherein the first labyrinth seal is part of a first sealing zone. Wherein at least a portion of the stationary element includes the teeth of a second labyrinth seal. And wherein the second labyrinth seal is part of a second sealing zone.
