Cryogenic air separation with dual feed air side condensers. |
摘要 |
<p>A cryogenic air separation system comprising at least two columns (105, 130) wherein a portion of the feed air (100) is turboexpanded (102) to generate refrigeration, one part (146) is condensed against vaporizing product (144) from the air separation plant, another portion (106) of the feed air is condensed against vaporizing higher pressure product (142) from the air separation plant, and all of the resulting feed air streams are fed into the same column (105) to undergo separation. <IMAGE></p> |
