- Abstract:
- Aluminaredmud has not been utilized effectively due to its highemission andstrong alkaline．In— dustrial flue gas whichhas high S02 should be desulfurized to meet up to the standards．The mineral component，chemicalcomposition，grain sizeandmicrostructure ofalumina redmud from Henan BranchofChinaAluminum Co．were determined in this article．The orthogonal experiments and single factor experiments have been done in the self—designed 1700×60mmglass absorption device which accessories were installed in the laboratory．The influential factors such as liquid-solid ratio，flue gasflow，and liquid—gas ratio were examined throughthe orthogonal tests．The optimal conditions：liquid—solid ratio is 7：1(kg／kg)，fluegas flow is 3．6 m’／h liquid-gas ratio and 12 L／m3．Under these conditions．the maximum efficiency ofFGD is more than 95％．At the sametime，compared with the currentlimestone—gypsum wetmethod，underthe same conditions redmudhas a better absorption effects．
