Abstract:

Performance of simultaneous desulfurization and denitrification from N2-NO-SO2 simulated flue gas using sodium chlorite as the additive and urea as the reductant in a rotating packed bed was investigated. In RPB, various rotational speeds, the flow rates of SO2, the flow rates of NO and the liquid flow rates were studied by means of the calculation of the removal efficiencies of SO2 and NO. The experimental results showed that the removal efficiency of SO2 was higher than 99.00% under various experimental conditions, while the removal efficiency of NO exhibited different results. A better simultaneous desulfurization and denitrification behavior could be obtained under the conditions of a SO2-NO-N2 simulated flue gas with the ratio of SO2/NO/ N2=6:4:8.33(v), a rotational speed of 460 rpm and an absorbent flow rate of 120 L/h.
