Abstract
Abstract A complex oxidizing agent combination made up of KMnO4 and NaClO was used to investigate the simultaneous absorption of NO and SO2 from sintering flue gas in a spray absorption tower on a laboratory scale. The effects of various operating parameters, i.e. initial gas temperature (Tg), initial solution pH, molar ratio of NaClO/KMnO4 (M), initial NO inlet concentration (CN) and SO2 initial inlet concentration (CS), were systematically investigated in the experiments. The results showed that the removal efficiency of SO2 was slightly affected by the reaction conditions and remained stable above 98%; however, the removal efficiency of NO was significantly influenced. It presented different trends with the reaction condition changed. The most optimal experimental conditions for simultaneous removal of NO and SO2 were found to be initial solution pH=5.5, Tg=50°C, M=3; in this case the average removal efficiencies of NO and SO2 could reach 98.8 and 70.9%, respectively.
