Abstract

A cryogenic air separation system having a main condenser (32) comprising a plurality of tubes having fluted external condensing surfaces upon which downf lowing nitrogen vapor (10) condenses, and having structured internal boiling surfaces upon which downf lowing oxygen liquid vaporizes. The main condenser (32) is employed as a condenser/reboiler located within a lower pressure column (31) to condense nitrogen vapor (10) from a higher pressure column (30) and partially vaporize oxygen liquid from the lower pressure column (31).
