Forced Circulation Evaporators are specially designed for liquids that tend to scale, foul, highly viscous and crystallize depending upon the final concentration of the product. Feed is re-circulated in the shell and tube heat exchanger by pumping, heated under pressure to prevent boiling, and then flashed in the vapor liquid separator, where the absolute pressure is slightly less than in the heat exchanger, to obtain the required vaporization
