Zusammenfassung:A urea solution for absorbing NOX contains CO(NH2)2 (5-12 Wt%), H2O2 (0.5-2) and water (rest). A process for cleaning the waste gas containing NOX by said urea solution includes such steps as closed-loop circulation absorption by use of 2-3 nitric acid solution absorbing towers and closed-loop circulation absorption by use of 1-2 absorbing towers containing said urea solution. Its advantages are high efficient and no secondary pollution.
