Abstract In this research, an ultrasound assisted CO2 absorption system using different absorbents has been investigated. Ultrasonic atomization technology is one of the efficient methods to increase gas-liquid interfacial area, thereby absorption rate. First of all, the significance of each operational parameter on the absorption rate was investigated by applying the experimental design methodology. The response surface methodology (RSM) and Box-Behnken design were employed to determine the experimental design. The analysis of variance revealed the adequacy and accuracy of the proposed models. The results indicated that among the investigated variables, the input power played more important role in the absorption rate. In addition, the absorption rate was not sensitive to the temperature. Moreover, a comparative study using water absorbent indicated that applying ultrasonic atomization led to five times faster CO2 absorption rate compared to the conventional stirring method and 20 times faster rate compared to the silent condition (no ultrasonic and no stirring).
