Side column low temperature rectification system for producing low purity oxygen |
| abstract |
The present invention relates to a low temperature rectification system using a double column and a secondary side column, wherein the system is capable of condensing compressed air which can be adjusted to a low head pressure, thereby reducing oxygen of low purity that can lower operating costs. Provided is a sesame that can be produced.n n n ※ Selection first degree |
