The absorption of gas pollutants including COD CO, NO, NO2, SO2, and H2S from the exhaust of a paint recuperative oxidizer into NaOH solution has been studied using an industrial scale dynamic scrubber. Experimental results show the influence of the absorbent concentration on the pollutant removal efficiency. The best removal efficiencies of CO2, CO, NO, NO2, SO2, and H2S were 79, 80, 80, 100, 75 and 88 %, respectively, with 2 % NaOH as the absorbent. A comparison of these results with previous studies shows that the liquid-to-gas flow rate ratio (FL/FG) in this dynamic scrubber is much smaller than for traditional NaOH scrubbers and spray dryers.
