Abstract

A process for purifying a polluted fluid which comprises heating the polluted fluid and evaporating the components of said polluted fluid which are more volatile while simultaneously concentrating the pollutants into a residue, introducing said residue to a combustion chamber where it is at least partially burned and introducing the heat of combustion as the only source of heat to the evaporation stage of the process.
