May 15, 2015 · evaporation the liquor is recirculated to the top of the vessel where it is distributed and falls as a thin film on the heating surface, as shown in Figure 4. Falling film evaporators provide for better heat transfer rate than rising film (also called LTV) evaporators and significantly Figure 4. Falling film evaporation Figure 3.

solute becomes a part of the crystal lattice and heat of crystallization is liberated. Finally, the liberated heat must flow back to the bulk of the solution. In most crystallization systems the solute diffusion resistance is less than the resistance offered by the surface reaction. For these systems it is assumed that McCabe's AL law holds (l8).

Crystallization (ZLD) - Lenntech

The forced-circulation evaporator is normally fed by an external source of steam heating which is used due to the high boiling point rise (BPR) of the solution at high concentration. The crystallizer needs ca. a bit more than 1 ton of steam to evaporate 1 ton of water. Highly Soluble Salts and Evaporator BPR

The need to provide boilers with high-quality feedwater is a natural result of the advances made in boiler performance. The ratio of heating surface to evaporation has decreased. Consequently, heat transfer rates through radiant water wall tubes have increased-occasionally in excess of 200,000 Btu/ft²/hr.
