Abstract:
1. A system for scrubbing gaseous effluent, the system comprising: (a) a packed column comprising (i) a gaseous effluent inlet, (ii) a packing region for housing packing for contacting the gaseous effluent with an aqueous hydrogen peroxide composition, and (iii) a gaseous effluent outlet that directs said gaseous effluent out of said packed column after it has contacted said aqueous hydrogen peroxide composition in said packing region; (b) a fluid line in fluid communication with said packed column and arranged with respect to said packed column to remove said aqueous hydrogen peroxide composition from said packed column after it has contacted said gaseous effluent and introduce said aqueous hydrogen peroxide composition into said packing region; (c) a source of hydrogen peroxide arranged to provide said hydrogen peroxide to said fluid line; and (d) a source of at least one additive arranged to provide said at least one additive directly to said fluid line whereby said at least one additive mixes with said hydrogen peroxide in said fluid line to decompose said hydrogen peroxide to predominantly hydroxyl free radicals and thereby produce said aqueous hydrogen peroxide composition.
