Forced Circulation Evaporators
The Forced Circulation evaporator is designed for evaporation of liquids with a high solids content, high viscosity, tendency to foul, and also for crystallizers.
Process
The system is often used as a finishing evaporator for concentration of liquids to a high solids content following a low solids multi-stage, TVR evaporator or MVR evaporator.
Boiling in the Forced Circulation evaporator is suppressed in the heat exchanger by backpressure and takes place when the liquid enters the lower pressing separator champer.
Applications
Typical applications include processes for salt, stillage, corn steep water, Calcium carbonate and crystallizing evaporators.
