Method and apparatus for use of reacted hydrogen peroxide compounds in industrial process waters

A method for removing at least one of an odor component and a noxious component from an atmospheric effluent, the method comprising:

• contacting an atmospheric effluent containing at least one of an odor component and a noxious component with an aqueous hydrogen peroxide composition, said aqueous hydrogen peroxide composition comprising hydrogen peroxide and at least one additive that catalyzes the decomposition of said hydrogen peroxide to predominantly produce hydroxyl free radicals;
• oxidizing at least one of said odor component and said noxious component in said atmospheric effluent to substantially non-odor-offensive, environmentally acceptable by-product, said oxidation producing a liquid effluent containing at least said by-product and said aqueous hydrogen peroxide composition, and a gaseous exhaust effluent having reduced amounts of at least said odor component and said noxious component;
• and
• removing at least a portion of said liquid effluent to a waste treatment facility where said liquid effluent becomes at least one of an effective charge neutralization agent and an adsorbing agent in a wastewater treatment process.

A packed scrubber system for removing at least one of an odor component and a noxious component from an atmospheric effluent, said system comprising:

• a packed scrubber tank, said packed scrubber tank comprising:
• an atmospheric effluent inlet, said atmospheric effluent inlet for introducing atmospheric effluent containing at least one of an odor component and a noxious component into said packed scrubber tank;
• a packed column, said packed column for providing an increased surface area on which said atmospheric effluent can contact an aqueous hydrogen peroxide composition that can oxidize at least one of said odor component and said noxious component in said atmospheric effluent to produce substantially non-odor-offensive, environmentally acceptable by-product which exit said packed column as a liquid effluent and a gaseous exhaust effluent having reduced amounts of at least one of said odor component and said noxious component;
• at least one dispenser arranged for delivering said aqueous hydrogen peroxide composition into said packed column;
• a reservoir, said reservoir for collecting said liquid effluent;
• an atmospheric vent, located above said packed column for out-letting said exhaust effluent from said scrubber tank;
• and
• an aqueous hydrogen peroxide composition delivery system connected to said packed wet scrubber tank, said aqueous hydrogen peroxide composition delivery system comprising:
• at least one sidestream effluent pump, said sidestream effluent pump for delivering said aqueous hydrogen peroxide composition to said at least one dispenser, said sidestream effluent pump being in fluid communication to said reservoir to withdraw a portion of said liquid effluent as a sidestream effluent on the vacuum-side of said sidestream effluent pump and connected to said at least one dispenser on the back-stream side of said sidestream effluent pump;
• wherein said aqueous hydrogen peroxide composition comprises hydrogen peroxide and at least one additive that decomposes said hydrogen peroxide to predominantly hydroxyl free radicals, said aqueous hydrogen peroxide composition being added to said sidestream effluent for delivery to said at least one dispenser.

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 sidestream subsystem comprising at least one pump and plumbing 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 sidestream subsystem;
• and
• (d) a source of at least one additive arranged to provide said at least one additive to the sidestream subsystem whereby said at least one additive mixes with said hydrogen peroxide in said sidestream subsystem to decompose said hydrogen peroxide to predominantly hydroxyl free radicals and thereby produce said aqueous hydrogen peroxide composition.
