Influence on Desulfurization Capacity of Flue Gas Desulfurization Solution

Abstract:

In view of troubles during the operation of desulfurization device for Pangang 260 m² sintering machine, influence on absorption/desorption capacity of the desulfurization solution was investigated, including concentrations of Na⁺, SO₄^2- and desulfurization solution. The results showed that it was beneficial for sulfur dioxide (SO₂) absorption and there was no significant effect on desorption efficiency, when Na⁺ and SO₄^2- concentration was lower than 15 g/L and 67 g/L, respectively. When the concentration of desulfurization solution reached 113 g/L, Na⁺ and SO₄^2-concentrations had no significant effect on absorption/desorption of the desulfurization solution. The results also indicated that desorption was more difficult with higher of the desulfurization solution concentration. The desorption efficiency of 113 g/L desulfurization solution was 10 %-17 % lower than that of 69 g/L desulfurization solution.
