Gaseous nitrogen oxides were scrubbed with water at 298/sup 0/K and at near atmospheric pressure in towers packed with 6- and 13-mm Intalox saddles. Nitrogen oxide removal efficiencies from 55 to 97% were obtained over a wide variation of packing depths. Other studies concerning the depletion of nitrous acid in packed towers are also presented. A mathematical model was developed based on the mass-transfer information for packed towers and chemical-reaction and mechanistic phenomena specific to the NO/sub x/-HNO/sub x/-H/sub 2/O system. Calculated NO/sub x/ removal efficiencies utilizing this model agree with the observed experimental phenomena fairly closely. The model is presented and discussed along with the results of the experimental activities.
