Spray scrubbing of the nitrogen oxides into NaClO2 solution under acidic conditions.

摘要: The operating conditions of this study were closed to the typical flue gas desulfurization system in coal-fired power plant. objective was investigate absorption performance lean NO an aqueous solution acidic sodium chlorite using a bench-scale spraying column. conversion and NOx removal efficiency increasing with concentration, retention time, temperature, decreasing initial pH solution. As concentration higher than 0.4 M, 100% 80%, respectively. under 4-7 that > 7. It meant process might be suitable combining traditional wet system. NO2/NOx ratio effluent 0.5, it absorbed second scrubbing column operated alkaline condition.
