ABSTRACT:
A cryogenic air separation system comprising at least two columns wherein a portion of the feed air is turboexpanded to generate refrigeration, one part is condensed against vaporizing product from the air separation plant, another portion of the feed air is condensed against vaporizing higher pressure product from the air separation plant, and all of the resulting feed air streams are fed into the same column to undergo separation.
