Glossary
Time for the cut
118
The pressure P2 is set a little lower than
pressure P3.
The result:
- the components are flushed into the
atmosphere as soon as they leave the first
column.
Since the pressure on the left of the coupling
capillary is lower than that on the right, the
gas present in the first column is transported
to the cut output!
