摘要:
A cryogenic air separation system wherein nitrogen vapor from a higher pressure column and oxygen liquid from a lower pressure column each pass down through a once-through main condenser in heat exchange relation and some but not all of the oxygen liquid is vaporized such that the oxygen liquid and vapor exit the condenser in a liquid to vapor mass flowrate ratio within the range of from 0.05 to 0.5 whereby the need for a recirculation pump to ensure avoidance of oxygen boiling to dryness is eliminated.
