Abstract

NOXis a major pollutant that causes acid deposition and photochemical smog. A large amount of NOXis emitted from combustion sources such as power plants. As some articles have indicated, NOXremoval with NaClO2solution in an absorption column is an effective control approach. In this approach, first insoluble NO is oxidized into water-soluble NO2under acidic conditions, then NO2is removed in alkaline NaClO2solutions. The results indicate that the reaction rate constant is 9.1×104(L)4.4/cm6/s/mol2.4in the first absorption column with acidic conditions, and the reaction orders with respect to NO and NaClO2are 1.4 and 2, respectively. In the second absorption column with alkaline conditions, the reaction rate constant is 3.2×107(L)5.2/cm6/s/mol3.2and the reaction orders with respect to NO and NaClO2are 1.6 and 2.5, respectively. The activation energies in the first and second absorption column are 71.8 and 139.6 kJ/mol, respectively.
