Question

to separate salt from water in a seawater mixture, what process is used?​

Answer 1

Answer:

Water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates. It is then cooled and condensed into a separate container.

Answer 2

Distillation is used for separating salt from sea water.

Explanation:

• Distillation is an effective method to separate mixtures that are comprised of two or more pure liquids.

• Distillation is a purification process where the components of a liquid mixture are vaporized and then condensed and isolated.

• Distillation is a phase separation method where saline water is heated to produce water vapor. It is then condensed to produce freshwater.

• The various distillation processes used to produce potable water includes Multi Stage Flash, Multiple Effect, Vapor Compression and waste-heat evaporators.

• All these processes generally operate on the principle of reducing the vapor pressure of water within the unit to permit boiling to occur at lower temperatures, without the use of additional heat.

• Distillation units routinely use designs that conserve as much thermal energy as possible by interchanging the heat of condensation and heat of vaporization within the units.

• The major energy requirement in the distillation process thus becomes providing the heat for vaporization to the feedwater.
