Multiple effect evaporation under vacuum is still used in sugar production as well as in the manufacture of condensed milk, soap, glue, and many other products. The Rillieux evaporator was one of the earliest innovations in chemical engineering and remains the basis of all modern forms of industrial evaporation. It is perhaps most extraordinary that Rillieux invented his device before the ...

A multi-effect vacuum evaporator consists of a set of interconnected evaporators where the first effect is the first evaporator, and so on. Using a multiple effect evaporator, the operation is based on the steam produced in one effect being used as the heat source for the following effect. As the temperature decreases from one effect to the next, the vacuum is increased so that the boiling point is lower and evaporation …

MVR Evaporator Working principle: MVR is called Mechanical Vapor Recompression. It use the centrifugal compressor to re-compress the secondary vapor(low temperature and low pressure) which is evaporated from the liquid material to rise its temperature and pressure, so as to reuse it as heating source to evaporate the liquid material again.

Multiple-effect distillation or multi-effect distillation (MED) is a distillation process often used for sea water desalination. It consists of multiple stages or "effects". In each stage the feed water is heated by steam in tubes, usually by spraying saline water onto them. Some of the water evaporates, and this steam flows into the tubes of the next stage (effect), heating and evaporating ...

A simple evaporator system (Fig 1) has a single evaporation chamber, or effect, and is said to have an "economy of one." Evaporator economy can be increased by increasing the number of effects. A multiple effect system (Fig 2) uses the vapor from the first effect as the steam source for each subsequent effect. As the temperature decreases in ...

01.04.2010· A typical rotary evaporator has a water bath that can be heated in either a metal container or crystallization dish. This keeps the solvent from freezing during the evaporation process. The solvent is removed under vacuum, is trapped by a condenser and is collected for easy reuse or disposal. Most labs use a simple water aspirator vacuum on ...
