Cryogenic rectification system for fluorine compound recovery |
| 摘要 |
<p>The method is effected using appts. having a mass transfer contacting device (4) supplied with a wash liq (7) and a feed (1) contg. F cpds . Liq leaving the device is passed to a first rectification column (26). In one aspect a second rectification column (49) receives liq. from the bottom of the first column. F cpds are recovered from the upper part of the or both columns. The appts. is also claimed.</p> |
