Seawater containing 3.50 wt% salt passes through a series of 10 evaporators. Roughly equal quantities of water are vaporized in each of the 10 units and then condensed and combined to obtain a product stream of fresh water. The brine leaving each evaporator but the 10th is fed to the next evaporator. The brine leaving the 10th evaporator contains 4.70 wt% salt. It is desired to produce 2 x 104 L/h of fresh water. How much seawater must be fed to the process in kg/h?

Question


Seawater containing 3.50 wt% salt passes through a series of 10 evaporators.

Roughly equal quantities of water are vaporized in each of the 10 units and then condensed and combined to obtain a product stream of fresh water.

The brine leaving each evaporator but the 10th is fed to the next evaporator.

The brine leaving the 10th evaporator contains 4.70 wt% salt.

It is desired to produce 2 x 104 L/h of fresh water.

How much seawater must be fed to the process in kg/h?

Expert Solution
Step 1

Given that feed containing 3.5 wt % 10 evaporators are in series given Equal quantities of water vaporized Product containing brine having 4.7 wt % salt w = 2 x 104 lth
