摘要： A method and apparatus for separating air in which the recovery rate of an oxygen product is increased by increasing the liquid to vapor ratio in a lower pressure column connected to a higher pressure column in a heat transfer relationship. A crude liquid oxygen column bottoms stream produced in the higher pressure column is partially vaporized against condensing argon-enriched vapor of the lower pressure column which is fed back to an argon stripping section of the lower pressure column. A supplemental nitrogen-rich reflux stream and an oxygen-enriched stream having a greater oxygen content than the crude liquid oxygen stream are fed into the lower pressure column. These streams are formed from a two phase stream produced, at least in part, from the crude liquid oxygen stream after the partial vaporization thereof.

摘要： An oxygen production method and apparatus including an air separation plant and a heat exchanger in which a pumped liquid oxygen stream is heated within the heat exchanger through indirect heat exchange with compressed air to produce a pressurized oxygen product. The liquid oxygen stream is pressurized to above about 55 bar (a) and no greater than about 150 bar (a) and is a supercritical fluid after having been heated. The air is compressed to an air pressure that is a function of the oxygen pressure that will result in a minimum power being expended in the compression of the air. The heat exchanger can be a brazed fin heat exchanger fabricated from aluminum in which the fins located in heat exchange passages have an undulating configuration to increase the flow path length and induce flow separation and thereby increase the heat transfer coefficient within the heat exchanger.

摘要： A method of separating air in which a superheated air stream is introduced into a mass transfer contacting zone associated with a higher pressure column of an air separation unit. Krypton and xenon is washed from a superheated air stream introduced into the mass transfer contacting zone, thereby to form a krypton and xenon-rich liquid. The krypton and xenon- rich liquid is stripped within a stripping column to produce a krypton-xenon-rich bottoms liquid. A krypton-xenon- rich stream composed of the krypton-xenon-rich bottoms liquid from the stripping column is produced for purposes of further refinement.
