Various Good Quality Forced Circulating MVR Multi-effect Evaporators and concentration System
Its working principle: use centrifugal steam compressor or other steam compression machinery to compress all the secondary steam to make its physical properties meet the requirements of heating steam, and use it as heating steam. In this evaporation process, fresh steam is needed only when starting up, and after normal operation, there is no need to input fresh steam, and no (or very little) secondary steam needs to be condensed, Therefore, MVR evaporation greatly saves steam, but uses more electricity.

During the crystallization process, substances are separated from one another by using different solution equilibria. Applications include salt extraction and fertilizer production.
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
Medium to high heat transfer coefficient, especially for low viscous product under turbulent conditions
High circulation flow-rate inside the heat exchanger
Evaporation does not take place on the heating surface, but in the flash separator
Long residence time due the high recirculation, therefore also high liquid hold-up
Vacuum operation or at atmospheric condition
Not suitable for sensitive product, due the long residence time
