Removal of SO₂ by Corona Discharge Combined with Fe (II) Catalysis

Abstract:

The effects of the supply voltage, water flow rate, concentration of inlet SO₂ and Fe²⁺ in liquid phase on the desulfurization efficiency were investigated by corona discharge with liquid phase on the condition of DC discharge and pulse discharge. The experimental results showed that the desulfurization efficiency increased with the increasing of the supply voltage, water flow rate, and concentration of Fe²⁺. However, the desulfurization efficiency was nearly unchanged with the increasing of the initial concentration of SO₂. The desulfurization efficiency in pulse discharge was better than that of the DC discharge on the same condition, and the highest desulfurization efficiency could be more than 99%.
