The Tubular Forced Circulation Evaporator FCE is the right solution to
concentrate streams containing a big amount of suspended solids,
medium-highly viscous fluids and products with high tendency to fouling.
This kind of evaporator is also widely used as crystallizer, where
special separator designs are used to separate crystals from the
recirculated crystal slurry.
It is particularly suited as high
concentration step in multiple-effect (ME) evaporation, thermal vapor
recompression (TVR) or mechanical vapor recompression (MVR) arrangement
because the forced circulation evaporator can handle more concentration
values and/or higher solid content than a falling film evaporators.
In
a multi-stage system, Forced Circulation Evaporators can be used in
combination with Thin Film Evaporators/Dryers or with Falling Film
Evaporators
