Swenson Walker Crystallizer.
Swenson Walker Crystallizer
The set-up is designed to demonstrate and stimulate the phenomena of
crystallization. Swenson Walker crystallizer is a continuous type
This operation involves both heat and mass transfer.
Crystallization is the formation of solid particles within a homogeneous
phase. Its wide use has a two-fold basis; a crystal formed from an
impure solution is itself pure.
The setup consists of a top open
jacketed round bottom trough. A ribbon mixer is provided in crystallizer
trough, which rotates at low rpm for agitation of saturated solution.
The saturated solution is prepared in a tank fitted with heater and a
stirrer. This hot saturated solution is fed at one end of the
crystallizer and flows slowly towards the other end while being cooled
and is allowed to flow back in hot feed tank making the process
continuous. The crystals sediments at the bottom of the trough, and can
be washed out at the end of process. Arrangement for Cooling water
circulation and flow measurement in jacket is made by using storage type
water tank, a pump and a rotameter. Necessary instrumentation is done
for temp measurement
