Comparison of Treatment Kinetics for Removal of Btex Compounds and Chlorinated Solvents Using Advanced Oxidation Processes

This paper addresses the process interactions from combining integrated processes (such as advanced oxidation processes (AOPs), biological operations, air stripping, etc.). AOPs considered include: Fenton's reagent, ultraviolet light, titanium dioxide, ozone (O3), hydrogen peroxide (H2O2), sonication/acoustic cavitation, among others. A critical review of the technical literature has been performed, and the data has been analyzed in terms of the processes being additive, synergistic, or antagonistic. Predictions based on the individual unit operations are made and compared against the behavior of the combined unit operations. The data reported in this paper focus primarily on treatment of petroleum hydrocarbons (e.g., benzene, toluene, ethylbenzene, and xylene) and chlorinated solvents. The kinetic data included in this study are obtained both from the technical literature and from research investigations of the authors. The results of this study will be discussed.
