SIM 3210 Evaporator

 Model Description

The model shows the typical arrangement found in a simple desalination unit.

First, a brine is passed into a kettle type heat exchanger, this brine is then heated with low pressure steam to cause the water to evaporate.

Then, the evaporated water is cooled and condensed to provide desalinated water.

Lastly, a strong brine is then released.

The level of the brine held in the evaporation vessel is controlled by varying the exit flow of strong brine.

By adjusting the placements of their feed valves, one may regulate the flow of low pressure steam and brine simultaneously.
