摘要： Air is raised in pressure by a compressor and pre-purified by removal of impurities, particularly H.sub.2 O vapor and CO.sub.2, in an adsorption unit. The resulting air is cooled in a heat exchanger, and is subjected to a first rectification in a rectification column in which the air is separated into a nitrogen-rich fraction and an oxygen-rich fraction. A further oxygen fraction enriched in argon is subjected to a second rectification in which argon is separated from oxygen in a second rectification column. First and second argon products of different purity are withdrawn from the second rectification column through outlets thereof.

The process comprises separating a heated, compressed crude argon stream containing nitrogen and oxygen into an oxygen permeate stream and an oxygen-depleted argon stream by passing the compressed heated argon stream through a solid electrolyte membrane selective to the permeation of oxygen.

摘要： The present invention is directed to a method for recovering argon from a feed mixture comprising argon, carbon monoxide, carbon dioxide, nitrogen, and hydrogen which comprises the steps of (a) purifying the feed mixture to remove contaminants, (b) compressing the purified feed mixture to a separation pressure, and (c) passing the compressed purified feed mixture through a pressure swing adsorption system to separate carbon monoxide, carbon dioxide, and all or most of the nitrogen from the mixture as adsorbed products and to produce an argon-rich fraction as a non-adsorbed product. The argon-rich fraction from step (c) may be further purified by passing the fraction to a cryogenic fractional distillation system to separate hydrogen and any remaining nitrogen from the fraction as a distillate product and to produce a pure argon product. In a second and third embodiment, the invention is directed to a method for recovering argon from a feed mixture comprising argon, carbon monoxide, carbon dioxide, nitrogen, and oxygen, wherein oxygen is removed from the argon-rich fraction exiting the pressure swing adsorption system in step (c) by passing the fraction to a second pressure swing adsorption system before or after further purification of the fraction in a cryogenic fractional distillation system.

摘要： A process and apparatus for the ultrapurification of cryogenic low boiling liquified gases such as oxygen and nitrogen which contain trace impurities. The impure gas is introduced into a first distillation column provided with a top column condenser and a bottom column reboiler. The impure gas is substantially at its liquid-gas equilibrium temperature at the pressures within the first distillation column. Here the gas is separated by distillation into a first vapor fraction containing low boiling point impurities and a first liquid fraction containing high boiling point impurities. The first vapor fraction is withdrawn and introduced into a second distillation column provided with a top column condenser and a bottom column reboiler. The first vapor fraction is substantially at the liquid-gas equilibrium temperature at the pressures within the second distillation column. Here the vapor fraction is separated by distillation into a second vapor fraction containing low boiling point impurities and a second liquid fraction free of trace impurities which is withdrawn as product. Cooling for the process is provided by indirect heat exchange with a cryogenic low boiling gas such as nitrogen, oxygen, or air. The gas to be purified as well as the heat exchange gas can be obtained from a standard air separation unit or the process can be conducted using gases and liquids obtained from storage.
