High efficient factory price vacuum multi effect falling film evaporator/evaporation crystallizer


Multiple Effect Evaporation

The multiple effect evaporation processes can optimise the energy efficiency of facilities through the recycling of vapour.



The vapour supplied during the first effect produces the vapour at a lower pressure. These vapours are then used in a second effect as a vapour heating steam.

The number of effects vary and can go right up to 8. The number of effects is chosen according to the investment and operating cost.

The vapours at the outlet of the last effect should be condensed.


Example Parallel flow principle

The solution enters the evaporator circuit of the first stage. Here it mixes with the circulated solution and is heated in heater H with steam. In the evaporator V1, solvent (water) evaporates while cooling the solution to the boiling temperature. The solution then flows to the second stage, which is operated under reduced pressure and thus at a lower temperature. The vapour generated in the first stage is used as a heating medium for evaporation of the solution in the second stage. This process can be repeated several times depending on the boiling point elevation of the solution and existing frame conditions. The vapour of the last stage is condensed via cooling water. If salt shall be crystallized in the plant, further evaporation concentrates the solution to such an extent that crystals are formed. If desired, the crystals in the suspension can then be separated from the solution and dried.

Suitable for any type of evaporator

The multiple effect evaporator can be made up of falling film, forced or flash-cooling circulation evaporators.



This technology is great when the cost of vapour is low.


Major Advantages of Multi-effect systems:

Ability to maximize usage of input energy (steam economy)

Reduced energy required to run full system

Reduced condensing load with additional effects (less cooling water needed)

Liquor flow control

Convenient foul condensate collection and processing

Ability to do online cleaning of individual effects

Maximum thermal efficiency with concurrent flow option
