In air separation plants, compressors work by increasing the pressure of the incoming air. Best efficiency is reached by using integrally geared compressors, this technology enables intercooling after each impeller and can be applied over a wide range of flows, from 1000m³/h up to 1,500,000m³/h.
This high-pressure air is then cooled to very low temperatures, causing it to liquefy. The liquefied air is subsequently separated into its components, nitrogen, oxygen, and argon, based on their boiling points. Compressors are essential for achieving the necessary pressure and temperature conditions for efficient gas separation.
