column can be divided into three sections name
ly, enriching section,
stripping section and feeding tray. Feeding tray is the tray
/stage of distillation column
where the feed is introduced. Enriching section consists of
the trays above the feed tray
and is so named because in this section, rising vapors are enr
iched in more volatile
component. Since liquid is stripped off of the more volatile c
omponent in the section below
feeding tray, it is called stripping section
