Abstract: A new process was proposed for removing the nitrogen oxides(NOx) from the CO2 waste gases from the lime torrefied ratary furnace in Shanghai Baoshan Steel and Iron Company by means of absorption method of aqueous urea solution in order to recover highly pure CO2 for producing high quality beverage. The result obtained shows that the concentration of nitrogen oxides can be decreased from 6.5×10-4 mol/L to below 2.0×10-6 mol/L, the removing rate was over 99%. In the experiment, we made NO coming from the reaction NO2 +H2O be all oxidized to NO2 by using a special oxidized method, which was the key step for removing nitrogen oxides.

Key words: Urea, Water solution, Removing of nitrogen oxides, Refinement of CO2
