Experimental Study of Flue Gas Desulfurization by FeSO4 Aqueous Catalytic Oxidation |
| |
Abstract: | This paper studied the sulfur dioxide removal from flue gas by FeSO 4 aqueous catalytic oxidation in the filler tower.The factors that influenced the desulfurization rate more or less were confirmed through orthogonal experiments and the best favorable technical condition was obtained within experimental range.Moreover,the effect of the superficial gas flow rate,absorption temperature and inlet concentration of SO 2 on removal efficiency was studied,and the feasible technical condition was gained.Under the feasible technical condition,the continuous experiments showed that SO 2 removal efficiency reduced gradually within 80 min,afterwards,the downturn was solw and SO 2 removal efficiency was attained 51.2% in 180 min.The change of absorbent pH and SO 2 removal efficiency was synchronous,and absorbent pH had certain buffer capability. |
