METHOD AND APPARATUS FOR PROCESSING NITROGEN OXIDE GAS

摘要

34 In a method for processing nitrogen oxide, nitrogen oxide is reacted with hydrogen azide. Oxygen and/or plasma is utilized to accelerate the reaction between nitrogen oxide and hydrogen azide. An apparatus for use in performing the nitrogen oxide processing method includes a reaction casing in which an aqueous solution containing hydrogen azide is provided. A nitrogen oxide containing gas is introduced into the reaction casing for reacting nitrogen oxide with hydrogen azide to reduce nitrogen oxide. A plasma generating unit may be provided for feeding plasma into the nitrogen oxide containing gas.
