| Abstract: | A new method is studied to remove the nitrogen oxides （NOx） from the CO2 gas by means of urea solution absorption. The optimal conditions are. the temperature of solution is 40-60℃; gas ratio in the empty reactor is 5.4 cm/s; the ratio of the package height to reactor diameter is 9 ： 1 ; the spacing ratio of package is 68%; the filled urea is 0.8 times of the package and the concentration of the urea solution shouldn＇t be lower than 4.86 mol/L. The method is a kind of green chemical process which is simple and feasible. |
