Study On The Technology And Mechanism Of Simultanous Removal Of SO₂ And NO_X From Flue Gas In Aqueous Solution

On the basis of studying on the former experimental study of desufurizaiton and denitrificaiton in Chlorite Sodium solution, the experiments for removal of NOX and SO2 from simulating actual flue gas using a bench-scale bubbling reactor are carried out in this paper. The change of conformation in chlorite sodium solution is analyzed by the method of measuring iodine continuously. The results indicate that there is mainly ClO^2-in the solution. The reaction products are also analyzed by chemical analysis methods, respectively. The results indicate that there are mainly NO₃^-,SO₄^-å’ŒCl-in the solution. As a result, the equation of this reaction is deduced. ThenΔG , K , partial pressure ofNO and SO2 andΔH are calculated .The reaction partial progression of SO₂ and NOX is determined by initial concentration method. The reaction is divided to two stages including rapid reaction and slow reaction. The partial progression of rapid reaction is 2 and 3 respectively.
