    Abstract: A flue gas stream from fossil fuel fired sources and process gas streams from chemical, petroleum, and petrochemical operations and the like is directed to an exhaust duct, which conveys the flue gas stream containing nitrogen oxide contaminants into a quencher. The gas stream is conveyed through the quencher where aqueous medium is sprayed into contact with the flue gas stream. The quenched flue gas stream is mixed with ozone in a sub-stoichiometic amount for partial oxidation of NO X to form NO 2 and prevent the formation of N 2 O 5 . The flue gas containing NO 2 is absorbed into an acidic medium of a wet scrubber to form nitrous acid. The nitrous acid in the aqueous phase of the scrubber is mixed with selected compounds of ammonia to decompose the nitrous acid for release of nitrogen. The nitrogen oxide contaminants are removed from the flue gas stream in a process that minimizes the consumption of ozone and the operating costs associated therewith and eliminates the requirement to dispose of nitrate recovered from the scrubber purge stream.

    Abstract: This invention relates to methods and compositions for removing contaminants from fluids, for example, the removal of mercury contaminants by oxidation. The compositions and methods provided herein are robust and accomplish efficient removal of contaminants from fluid streams without the need for relatively expensive activated carbon. In addition, the methods and compositions of the present invention do not pose risks to the safety of workers through the injection of highly toxic, highly corrosive elemental bromine to directly oxidize the mercury. The compositions and methods of the present invention are versatile and apply to a wide range of contaminants including, but not limited to, mercury, lead, cadmium, thallium, and hydrogen sulfides. Further, the compositions and methods contained herein are capable of efficient contaminant removal over a wide range of temperatures and pressures.
