    • 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.
    • 来自化石燃料燃烧源的烟道气流和来自化学,石油和石油化学操作等的工艺气流被引导至排气管道,该排气管道将含有氮氧化物污染物的烟道气流输送到 猝灭剂。 气流通过淬灭器输送,其中将含水介质喷雾到与烟道气流接触。 骤冷的烟道气流与亚化学计量的臭氧混合,用于NO X的部分氧化形成NO 2并防止N 2的形成, /子> 0 <子> 5 。 含有NO 2的烟道气被吸收到湿式洗涤器的酸性介质中以形成亚硝酸。 洗涤器水相中的亚硝酸与选定的氨化合物混合以分解亚硝酸释放氮。 氮氧化物污染物在臭氧消耗和与其相关的运行成本最小化的过程中从烟道气流中除去,并且消除了处理从洗涤器净化流中回收的硝酸盐的要求。
