High recovery cryogenic rectification system |
| 摘要 |
<p>A cryogenic rectification system wherein oxygen-enriched liquid (107) from a higher pressure column (212) is vaporized against condensing nitrogen-containing fluid (208) which is employed as additional reflux (160) in the lower pressure column (210) thus increasing the column L/V ratio and the product recovery. <IMAGE></p> |
