Das Claude-Verfahren verbessert das Hampson-Linde-Zyklus by incorporating an expansion engine or turbine. A portion of the compressed gas does work in an expander, causing a much larger temperature drop (nearly isentropic expansion) than Joule-Thomson expansion alone. This provides more efficient cooling, making it the dominant Verfahren für die großtechnische Gasverflüssigung und -trennung heute.
