| Liquid-Liquid
Extractors |
| Features |
 The
countercurrent and continuous
liquid- liquid extractor has
series of mixing and settling
zones arranged in a vertical
fashion. - A common
agitator shaft provides an
agitator in each of the mixing
zone.
- A vertical
baffle protects the settling
zone from the turbulence in
the mixing zone. The variable
speed of the agitator gives
an additional control parameter
to handle applications with
various density differences.
- The
heavier liquid is fed at the
extractor bottom and the lighter
liquid at the top. The countercurrent
flow of the liquid phases
with multiple mixing and settling
steps ensures separation effect
of several batch extractions.
- The
use of solvent, labor and
power requirements is considerably
reduced.

of close boiling components, which
are otherwise difficult to separate
by distillation.
- Breaking of
azeotropes
- COD, BOD
reduction in wastewater.
- Purification
of fine chemicals and pharmaceuticals.
