Cryogenic air separation system for dual pressure feed |
摘要 |
A dual feed pressure cryogenic air separation system wherein all the feed air is pressurized to an intermediate pressure and cleaned of high boiling impurities at that intermediate pressure, and a portion further compressed to the high pressure and then cooled against another portion so as to prepare that other portion for the turboexpansion to the low pressure, preferably with the turboexpansion driving the further compression.
