Abstract: A method for removing Hg (mercury) from waste gases is disclosed, the removing of the mercury (Hg) gas (vapors) is by contacting the waste gas with a scrubbing agent being organic sulfoxides either in pure form or as with an emulsion of water-in-organic sulfoxides. The waste gas can be any waste gas containing mercury gases or mercury vapors, such as combustion flue gas and waste gases generated in various chemical and industrial processes.

Abstract: A method for removing acidic gases from waste gases is disclosed. The invention relates to a method for removing acid gases, in particular from SO2 and NOx, by contacting the waste gas with an emulsion of water in organic sulfoxides, in particular of water in oil-derived-sulfoxides. The organic sulfoxide phase can be regenerated after the emulsion is loaded with polluants, by letting the emulsion to settle down and separate into two phases. The aqueous phase obtained after the separation contains sulfate and nitrate ions which can be collected and used as valuable chemicals.
