An air separation process separates ambient or synthetic mixtures comprising primarily nitrogen, oxygen and argon into one or more streams that are enriched in one or more of the feed components. A typical example is the production of oxygen from air for use in a chemical process such as the conversion of a hydrocarbon into a synthetic gas stream comprising of hydrogen and carbon monoxide. A second example is the production of nitrogen from air for use as an inert gas for injection into oil or gas fields to enhance hydrocarbon production. A third example is the co-production of oxygen, nitrogen and argon streams in relatively pure form, as liquids and/or gases, for use in a variety of industrial applications.
