Preparation and Application of Mg(OH)2-based Desulfurization Emulsion from Alkaline Iron Slag
Mg(OH)2-based emulsion has been successfully prepared from the alkaline iron slag in the laboratory for the first time, and the wet Flue Gas Desulfurization (FGD) process with Mg(OH)2-based absorbents was researched through a simulated experimental set-up. The desulfurization efficiency was 89.0％～90.8％ under the conditions of sorbent concentration 21.2～63.6 g/L and the retention time (Ts) 30s. Effects of gas flowrate (Q), sorbent concentrate of Mg(OH)2-based emulsion and the retention time (Ts) on the desulfurization efficiency were also investigated in this paper. Research results indicated that Mg(OH)2-based emulsion is a new absorbents for wet FGD technology with investment-saving, low operation cost and high desulfurization efficiency.
