multiple-effect evaporator
Quick Summary
A multiple-effect evaporator is an industrial apparatus used to convert liquid into vapor. It consists of a series of evaporators where the pressure decreases progressively from one unit to the next. The vapor produced in one unit is used to heat the liquid in the subsequent unit, making the process more efficient than a single-effect evaporator.12
These evaporators are employed in various applications:
* Concentrating solutions: For example, in processing sugar and syrup.1
* Purification: Such as in the desalination of seawater, where water is vaporized, leaving mineral residues behind. The vapor is then condensed into purified water.13
* Refrigeration systems: Where the evaporation of a liquid refrigerant absorbs heat, producing a cooling effect.1
The process is a variation of distillation, where a liquid is converted to vapor and then condensed back into liquid form.3
