Removal of aqueous sulphur dioxide by magnesium oxide

Abstract

For stack gas desulphurization of thermal power plants the absorption of SO2 in the alkaline aqueous solution/slurry is a common method. In the present study the aqueous magnesium oxide powder has been studied for removal of aqueous dilute SO2. The aqueous sodium metabisulphite solution is used as SO2 source in place of SO2 gas. The effect of various parameters, like contact time, absorbent dose, initial concentration of aqueous SO2 solution on the SO2 removal have been reported in the present article. © 2005 - Kalpana Corporation.
