Cryogenic rectification system for producing low purity oxygen and high purity nitrogen |
| abstract |
A double column cryogenic rectification system for producing low purity oxygen and high purity nitrogen, preferably at elevated pressure, wherein nitrogen-rich vapor from the higher pressure column is turboexpanded and condensed against lower pressure column intermediate liquid prior to being passed into the lower pressure column. |
