ABSTRACT:
In the water purification process, apparatus, and method, contaminated water vapor is exposed to liquid solvent, which causes a transfer of contaminants from the contaminated water vapor to the liquid solvent. In an advantageous embodiment, this latter step is followed by a second purification step where the decontaminated water in liquid phase is exposed to water vapor which causes a transfer of solvent remaining in the decontaminated water to the water vapor. The energy freed during the condensation of the vapor can advantageously be used for evaporation of the liquids, optionally by compressing the vapors prior to condensation thereof within heat exchangers.
