摘要： The present invention provides a process for the production of nitrogen at relatively high yield and purity by cryogenic rectifiction of feed air characterized by

(1) introducing the major portion of the feed air into a rectification column which is operating at a pressure in the range of from 241 to 1000 kPa (from 35 to 145 psia), and wherein feed air is separated into nitrogen-rich vapour and oxygen-enriched liquid;
(2) condensing a minor portion of the feed air, at a pressure greater than that at which the column is operating, by indirect heat exchange with oxygen-enriched liquid;
(3) introducing the resulting condensed minor portion of the feed air into the column at a point at least one tray above the point where the major portion of the feed air is introduced into the column;
(4) condensing a first portion of the nitrogen-rich vapour by indirect heat exchange with vapourizing oxygen-enriched liquid;
(5) passing at least some of the resulting condensed nitrogen-rich portion to the column at a point at least one tray above the point where the minor portion of the feed air is introduced into the column; and
(6) recovering substantially the entire remaining second portion of the nitrogen-rich vapour as product nitrogen.

摘要： The present invention provides a process for the separation of feed air by countercurrent liquid vapor contact in a higher pressure column and a lower pressure column which are in heat exchange relation at a region where vapor from the higher pressure column cools to warm liquid from the lower pressure column characterised in that:

(A) liquid is withdrawn from the region of heat exchange relation;
(B) the withdrawn liquid is vaporized by indirect heat exchange with the major portion of feed air, which is at a pressure substantially the same as that of the higher pressure column, at an elevation lower than the region of heat exchange relation, to partially condense the feed air;
(C) at least some of the vapor portion of the partially condensed major portion of the feed air is introduced Into the higher pressure column, and
(D) at least some of the vapor formed in step (B) is recovered at a pressure which exceeds that of the lower pressure column.
