摘要： A method and apparatus for separating air to produce a gaseous oxygen product in which the air is separated in an air separation plant to conduct a cryogenic rectification process that utilizes higher and lower pressure compressed air streams. The higher and lower pressure compressed air streams are generated in two multistage compressors linked together so that the lower pressure compressed air stream is produced from intermediate stages and the higher pressure compressed air stream is produced from higher pressure compression stages. During turn-down operational conditions, one of the two multistage compressors can be shut down to decrease the flow of air and therefore, the production of the oxygen product.

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.

摘要： An air separation method in which a liquid air stream, produced by vaporizing a pumped liquid oxygen stream, is introduced into a lower pressure column and optionally, a higher pressure column of an air separation unit. The liquid air stream is subcooled by extracting a main air feed to the higher pressure column from a main heat exchanger at a temperature warmer than the liquid air stream to increase argon recovery in an argon column connected to the lower pressure column. This temperature is selected such that the liquid air stream approaches an average temperature of the return streams being fed into the main heat exchanger from the higher and lower pressure columns at a range between about 0.2K and about 3K.
