Abstract

A method of manufacturing ultra-oxygenated air with approximately 70% oxygen by liquefaction and rectification of air at low temperature in a two-column installation at different pressures, in indirect permutation of heat, in which air is separated in the rectification column at higher pressure in an oxygen-enriched liquid, which is introduced into the rectification column at lower pressure, and in gaseous nitrogen, a first part of which is condensed by changing heat with one part of the oxygen-enriched liquid, and the second part by heat exchange with a second liquid, containing approximately 70% oxygen, solid from the bottom of the rectification column at lower pressure, characterized in that the oxygen enriched liquid exiting the base of the column at higher pressure is separated into two fractions, the first of which is introduced in liquid state in the middle of the column of rect lower pressure and the second of which is the part of the oxygen-enriched liquid that ensures by vaporization the condensation of the first part of the gaseous nitrogen in the head of the column at higher pressure and then is inflated in the lower part of the column. the column at lower pressure, and because the second liquid, with approximately 70% oxygen, is expanded, before its vaporization with heat exchange with the second part of the gaseous nitrogen, at a pressure considerably lower than that of the column at lower pressure and then, after reheating in the vicinity of room temperature, it is evacuated under a pressure slightly lower than atmospheric pressure.
