Removal of SO2 and NO from flue gas by wet scrubbing using an aqueous NaClO2 solution

摘要: This study used a NaClO2/NaOH solution as the additive/absorbent to determine extent of NOx removal in wet scrubbing system. A combined SOx/NOx system was also tested. The experiments were performed bench-scale spraying sieve tray scrubber continuous mode. operating variables included NO and SO2 concentrations, L/G ratio, molar initial pH. results individual DeNOx show that maximum efficiencies ranged from 3.1 12.6%. DeSOx/DeNOx DeSOx 36.6 71.9% 89.4 100.0%, respectively. major parameters affecting are ratio dosage additive. parameter influencing is ratio.
