摘要

The operating conditions of this study are close to the typical operating conditions of flue gas desulfurization system in coal-fired power plants. The aim of this study is to investigate the absorption kinetics of SO2 and NO from simulated flue gas into an aqueous solution of acidic sodium chlorite using a bench-scale spraying column. The range of absorption rates measured in this study is between 1.91 × 10-11 and 9.59 × 10-10 mol s-1 cm-2. The range of rate constants measured in this study is between 1.32 × 107 and 1.21 × 108 (L mol-1)1.9 s-1, and the average rate constant is 6.16 × 107 (L mol-1)1.9 s-1. The activation energy and frequency factor are 129 Kcal/mol (53.97 KJ/mol) and 6.93 × 1016 [(L/mol)1.9/s], respectively.
