7. Vacuum distillation - Wikipedia

   en.wikipedia.org/wiki/Vacuum_distillation

   Vacuum distillation is often used in large industrial plants as an efficient way to remove salt from ocean water, in order to produce fresh water. This is known as desalination. The ocean water is placed under a vacuum to lower its boiling point and has a heat source applied, allowing the fresh water to boil off and be condensed.
