Other articles where Multiple-effect distillation is discussed: distillation: Multiple-effect distillation, often called multistage-flash evaporation, is another elaboration. Increasing global demand for fresh water is driving research and development of advanced desalination technologies. As a result, a detailed model of multiple. Distillation is an age old method which can remove all types of dissolved impurities from contaminated water. In multiple effect distillation (MED).

Introducing more stages between multiple effect distillation heat source and sink reduces the temperature difference between the spaces and greatly reduces the heat transport per unit surface of the tubes.

The energy supplied is reused more times to evaporate more water, but the process takes more multiple effect distillation. The amount of water distilled per stage is directly proportional to the amount of energy transport.

If the transport is slowed down, one can increase the surface area per stage, i. The salt water collected at the bottom of each stage can be sprayed on the tubes in multiple effect distillation next stage, since this water has a suitable temperature and pressure near or slightly above the operating temperature and pressure in the next stage.

Some of this water will flash into steam as it is released into the next stage at lower pressure than the stage it came from.

The first and last stages need external multiple effect distillation and cooling respectively. The amount of heat removed from the last stage must nearly equal the amount of heat supplied to the first stage.

The lowest pressure stages need relatively more surface area to achieve the same energy transport across the tube walls. The process is based on the evaporation multiple effect distillation seawater. This is done by moving the vacuum steam generated by the external energy source over a heating surface to heat the sea water feed on the opposite side of the heat exchanger plates.

In multiple effect distillation MED latent heat of steam is recycled several times to multiple effect distillation many units of distilled water with one unit of primary steam input. This is already being used in large capacity plants for treating sea water.

Multiple Effect Distillation (MED)

In the last cell, the produced steam condenses on a conventional shell and tubes heat exchanger. This exchanger, called multiple effect distillation condenser" is cooled by sea water. At the outlet of this condenser, part of the warmed sea water is used as multiple effect distillation of the unit, the other part is rejected to the sea.
