CRYOGENIC AIR SEPARATION SYSTEM FOR PRODUCING MODERATE PURITY OXYGEN AND MODERATE PURITY NITROGEN

摘要

A cryogenic air separation system wherein feed air is initially processed to produce a vapor and a liquid, the vapor is then processed in the rectifying section of a reflux condenser to produce moderate purity nitrogen, and the liquid is processed in the stripping section of the reflux condenser to produce moderate purity oxygen.
