The results of laboratory scale research have been presented on the effects of ozonation of carrier gas containing NO_x and SO₂ on by-products trapped in Dreschel washers with solution of sodium hydroxide. The controlling parameter in this process was the ozonation intensity determined by the molar ratio O₃/NO_x. The measured by-products in a scrubber were SO₃^2- , SO₄^2- , NO₂^- and NO₃^- ions. It has been shown that ozonation of flue gas favours oidation of nitrites to nitrates and sulfites to sulfates in alkaline solution. Some of these results were confirmed in a pilot scale studies. Pilot plant was located in Wroclaw CHP (Combined Heat and Power), which provided flue gas for testing at a rate of 200 m³/h from the OP-430 boiler. Exhaust gases were ozonized and captured simultaneously with SO₂. Sodium hydroxide was used in a pilot scale as an absorbent.
