| Abstract: | This work investigated the volatile organic compounds (VOCs) removal efficiency of the RPB equipped with blade packings using absorption. Methanol, methyl ethyl ketone and methyl acetate were used as the model VOCs herein. The VOCs removal efficiency (E) was observed to increase with the rotational speed and the liquid flow rate but decrease with the gas flow rate. Moreover, methanol absorption provided the largest E values owing to that the solubility of methanol in water was the highest among three VOCs, implying that the centrifugal force induced from the RPB equipped with blade packings did not affect the thermodynamic property of VCOs. In addition, when the gas flow rate was 50 L/min, the highest E values for methanol, methyl ethyl ketone and methyl acetate absorption were 89.8, 77.6, and 68.9, respectively. Consequently, the RPB equipped with blade packings would be more applicable to the removal of more soluble VOCs from gaseous streams of huge flow rate. |
