Industry
Designed
for
continuous
concentration
and
mother-liquor
recovery,
Hanpu’s
three-effect
falling
film
evaporator
(15,000
kg/h)
delivers
high
throughput
with
low
specific
steam
consumption.
Operating
under
vacuum
with
staged
effects,
the
system
reuses
latent
heat
to
minimize
utilities
while
protecting
heat-sensitive
actives,
intermediates,
and
APIs.

(E1→E2→E3)
achieves
a
steam
economy
of
~3.5–4.0
kg

optional

further
reduce

Process
Overview
-
Feed
&
Preheat:
Metered
feed
is
preheated
via
condensate/heat
recovery
to
cut
live
steam.
-
Effect
1:
Live
steam
heats
E1;
generated
vapor
becomes
the
heating
medium
for
E2.
-
Effect
2
&
3:
Successively
lower
pressures/temperatures
maintain
gentle
boiling
and
high
overall
ΔT
utilization.
-
Separation
&
Control:
Vapor–liquid
separators
ensure
clean
condensate;
inline
density
or
refractometer
governs
discharge/recycle.
-
Vacuum
&
Condensing:
Final
vapors
condense
in
a
surface
condenser;
non-condensables
are
removed
by
the
vacuum
system.
