Comp Engineering and Exports is the manufacturer of a complete range of Forced Circulation Evaporators with options of crystallization and additional accessories like elutriation legs, hydro cyclones, post product centrifuge / spray dryer for crystal separation / drying.
Forced Circulation Evaporators are short tube evaporators and are best used when the boiling of feed liquid on the heating surfaces is to be avoided due to the salting and fouling characteristics of the liquid. Thus in the Forced Circulation Evaporators the flow velocity in the tubes is kept very high.
In these evaporators the liquid is circulated at high velocities in the tubes of the heat exchanger while steam is provided in the chest. This liquid is partially evaporated when the pressure is reduced in the vapour-liquid separator to the corresponding boiling temperature. High volume, low head axial flow circulation pumps is used for re-circulating the crystal laden slurry in the evaporator and hence the operation of this evaporator is independent of the temperature difference. In the crystallizing operation crystals can be separated from the crystallizing slurry by adjusting the velocity of the circulating stream. These evaporators are ideal for handling liquors with high viscosity or which have a tendency to salt and scale during evaporation.
Comp Forced Circulation Evaporators is applicable in Effluent Treatments Plants, Chemical Industry and Salt Solutions.
