    摘要： A cryogenic air separation method and apparatus in which first and second liquid streams are produced. The first liquid stream has a higher oxygen content than air and can consist of a higher pressure distillation column bottoms and the second liquid stream, for instance, air, has a lower oxygen content than the first liquid stream and an argon content no less than the air. The second liquid stream is subcooled through indirect heat exchange with the first liquid stream and both of such streams are introduced into the lower pressure column. The second liquid stream is introduced into the lower pressure column above that point at which the crude liquid oxygen column bottoms or any portion thereof is introduced into the lower pressure column to increase a liquid to vapor ratio below the introduction of the second liquid stream and therefore, reduce the oxygen present within the column overhead.

    摘要： The invention relates to a process for producing oxygen or air enriched with oxygen, in which process: The air entering the process is cooled in a heat exchanger to near to the condensation point of air and the air is led to a separation unit formed of two or more chambers connected thermally to each other and comprising A and B halves, in which it is divided, using liquidization and evaporation processes, into two or more gaseous fractions. The process air is maintained at normal temperature, except for small pressure differences to maintain the flow of the air and to optimize the process. When the process air flows through the A half of the separation unit, the liquid oxygen concentrate separated from it is evaporated in the B half of the separation unit at such a pressure, lower than normal pressure, that the desired composition is obtained for the oxygen concentrate and the heat of liquidization released in the A half of the unit is transferred to the B half of the unit and is bound in it to the evaporation of the oxygen concentrate. The low-oxygen-content process air leaving the A half of the separation unit is led out of the process through the heat exchanger. The oxygen concentrate evaporated in the B half of the separation unit exits at the lower than normal pressure prevailing in the half in question, either as such, or through a boosting and cooling process to the heat exchanger, and from there out of the process. The liquidization and evaporation processes are carried out in the said separation unit in nearly reversible conditions, in such a way that the gas phase in each process and in each part of the separation unit is nearly in equilibrium with the liquid phase in the same part.

    摘要： The present invention provides a method of producing an oxygen-enriched air stream which includes compressing an air stream, dividing the compressed air stream into a first portion and a second portion, separating the second portion of the air stream to provide an oxygen gas product, introducing the oxygen gas product into the first portion of the compressed air stream to form an oxygen-enriched air stream, and then introducing the oxygen-enriched air stream to the process equipment, which may be by way of example a blast furnace.
