Abstract

This work examined the feasibility of ozone (O₃) absorption by H₂O₂ solution in a rotating packed bed (RPB). The O₃ removal efficiency was determined at various operating variables including RPB speed, gas flow rate, and liquid flow rate in three RPBs. For each RPB, the results demonstrated that the RPB speed positively affected the O₃ removal efficiency. Also, the O₃ removal efficiency increased with the liquid flow rate but decreased with the gas flow rate. Moreover, the obtained results indicated that the O₃ removal efficiency increased as the inner radius of the bed was increased and the outer radius of the bed was decreased. Furthermore, the developed method for O₃ absorption using H₂O₂ solution could provide the removal efficiency of more than 95%. Consequently, the novel method would have a great potential in the removal of O₃ from the exhausted gases.
