METHOD FOR REMOVING AND USING NITROGEN OXIDES FROM FUMES

摘要

A method of removing nitrogen oxides from a gas containing the same and utilizing the nitrogen oxides by oxidizing the same in a gas-liquid phase to obtain a solution and reacting the solution to obtain a nitrate in a single closed cycle stage, which comprises feeding an oxygen-containing gas and water to the gas containing the nitrogen oxides to oxidize the same while maintaining an intensive gas-liquid phase contact to form a surface-active dynamic foam phase containing an HNO3/HNO2 solution. 0223K
