Abstract

The injection of powdered sodium chlorite NaClO2s for mercury oxidation into ironore sintering flue gas has been evaluated by using the bench scale of tubular flow reactor where the flow rate and temperature of flue gas stream were controlled to 250 Nm3 hr−1 and 135 °C respectively and either 50 or 260 μg Nm−3 of the mercury concentration was introduced intentionally to the gas stream We have observed that 90 of Hg0 oxidation was obtained at 018 g Nm−3 NaClO2s injection indicating that the oxidized weight of Hg° by the loaded weight of NaClO2s is 1026 ±333 μgHg0 gNaClO2s−1 This result leads us to suggest that the simple injection of NaClO2s into the flue gas has the potential to achieve over 90 mercury control in practical application
