The absorption oflean NOx (200≳1000 ppm) gases in aqueous /% emulsions was investigated in a mechanically stirred vessel. The chemical reaction rate between NO, and P4 in an alkaline solution was shown zero order with respect to NOx concentration and three-seconds order to P4 concentration. In the presence of S0x=2, the chemical reaction rate between NOx, and P4 in alkaline solution was again zero order with respect to NOx concentration, but changed to second order to P4 concentration. In addition, a robust design method was also used to evaluate the relative importance of various processing variables on the performance of this deNOx process by P4$ solution. S/N analysis of the results indicated that the P4 concentration, liquor temperature and NOx, concentration were the major factors in affecting NOx absorption efficiencies.
