A backward feed multiple effect evaporator is better than forward feed for concentrating cold feed, because it provides . 1) For the same heat load and mass flow rate in the tube side of a shell and tube heat exchanger, one may use multipass on the tube side, because it:
Energetic Efficiency of Evaporation Plantsbuilt in 1908, was a patented multipleeffect circulation eva porator. This concentrated liquids in a gentle and efficient man ner in a way unparalleled in its time. It was easy to control and had a compact arrangement. Further technical developments led to the first Wiegand falling film evaporator, built in 1952, which combined these consider
To reduce the amount of steam needed, the evaporator is normally designed as a multiple-effect evaporator. Two or more effects operate at progressively lower vacuums and thus with progressively lower boiling points. In such an arrangement, the vapour produced in the first effect can be used as a heating medium in the next effect.

High energy efficiency due to multiple-effect arrangement or heating by thermal or mechanical vapor recompressor, based upon the lowest theoretical temperature difference. Simple process control and automation due to their small liquid content falling film evaporators react quickly to changes in energy supply, vacuum, feed quantities, concentrations, etc.
Process Evaporation Equipment and Systems Thermal KineticsMultiple Effect Evaporation The entire evaporator duty (amount of water or solvent being removed) can be segregated into multiple evaporator effects. The segregation of the duty is combined with a pressure gradient across the entire evaporator to allow for reuse of energy in the system. The figures below show how the multiple effect design concept functions.
Apr 21, 2018 · A multiple-effect evaporator uses the water vapor from one effect as the heating medium for the next effect, which operates at a lower boiling point. The latent heat in water vapor can also be reused by thermally or mechanically compressing the vapor to
