Abstract
A method for removing contaminants from the effluent from metal pickling operations by oxidizing the contaminants in the effluent, passing the oxidized effluent to a first scrubber thereby removing mixed acid vapors and some nitrogen oxides and passing these scrubbed gases to a second scrubbing system while injecting ozone into a duct between the first and the second scrubbing systems thereby to oxidize nitrogen oxides to higher oxides and scrubbing the oxidized nitrogen oxides gas stream in the second scrubbing system.
