The efficiency of photo-oxidation, chemical oxidation by sodium hypochlorite, and ozonization for the industrial-scale removal of volatile organic compounds (VOCs) and odors from gaseous emissions was studied by applying these treatments (in an experimental system) to substances passing through an emission stack of a factory producing maize derivatives. Absorption and ozonization were the most efficient treatment, removing 75% and 98% of VOCs, respectively, while photo-oxidation only removed about 59%. The emitted chemical compounds and odors were identified and quantified by gas chromatography-mass spectrometry (in full-scan mode). In addition to presenting the results, their implications for selecting optimal processes for treating volatile emissions are discussed.
采用光氧化、次氯酸钠化学氧化和臭氧氧化法对从玉米衍生物生产厂排放烟囱中挥发性有机化合物（VOCs）和气味的工业规模去除效率进行了研究。通过将这些处理方法（应用于实验系统）应用于通过排放烟囱的物质，吸收和臭氧氧化是最有效的处理方法，分别去除了 75%和 98%的 VOCs，而光氧化仅去除了约 59%。通过气相色谱-质谱联用仪（全扫描模式）对排放的化学化合物和气味进行了识别和定量。除了呈现结果外，还讨论了它们对选择处理挥发性排放的最佳工艺的影响。
