Abstract: Provided is a method for using selective non-catalytic reduction to reduce nitrogen dioxide in exhaust gas generated during an olefin production process. Nitrogen dioxide generated in a catalyst regeneration step of a continuous PDH process can be efficiently removed by the method of the present disclosure. Ultimately, the generation of visible fumes can be prevented through the removal of nitrogen dioxide.

Abstract: The present invention relates to a catalyst for removing aromatic halogenated compounds comprising dioxin, carbon monoxide and nitrogen oxide simultaneously and a method for preparing the catalyst, more particularly, a catalyst comprising 0.1 to 5% by weight of vanadium, 1 to 12% by weight of metals in 6A family and 0.1 to 10% by weight of Ag in titania carrier or, alternatively, a catalyst produced by impregnating said catalyst in 0.05 to 1M sulfuric acid solution to carry out acid treatment. The catalyst according to the present invention has improved efficiency for removing 1,2-dichlorobenzene as a reactant model of dioxin and carbon monoxide rather than existing catalysts and also, alternative efficiency for removing nitrogen oxide substantially equal to commonly known catalysts, so that the catalyst can effectively control various air pollutants contained in exhaust gas.

Abstract: Disclosed are an apparatus and a method for treating exhaust gas. The apparatus includes a pipe (2) for providing a flow path of the exhaust gas containing nitrogen dioxide from a stationary source combustion process using gases as a fuel. One or more nozzles (4) are installed in the pipe (2), which can spray air and a reducing or an oxidizing agent to the exhaust gas flowing in the pipe (2). Additionally, a storage tank (6) is installed to store the reducing or oxidizing agent therein. Furthermore, an injection pump (8) is connected to the storage tank (6) and nozzle (4) at a position between the storage tank (6) and nozzle (4) to feed the reducing or oxidizing agent from the storage tank (6) to the nozzle (4), and an air pump (10) is connected to the nozzle (4) to feed the air into the pipe (2).
