The Tubular Forced Circulation Crystallizer FCC is similar to the Forced
Circulation Evaporator FCE, where special separator designs are used to
separate crystals from the recirculated crystal slurry.
It is an
evaporative crystallizer mainly used with products having relatively
flat or inverted solubility relative to the temperature. It is also used
with compounds crystallized from solutions with scaling components,
often for recovery/purification or elimination of products from liquid
effluents (e.g. Zero Liquid Discharge system, ZLD).
circulation crystallizer is particularly suited as final step in
multiple-effect (ME) evaporation, thermal vapor recompression (TVR) or
mechanical vapor recompression (MVR) arrangement because it can handle
high solid content.
In a multi-stage system, Forced Circulation
Crystallizers can be used in combination with Forced Circulation
Evaporator or with Falling Film Evaporators
