High frequency ultrasonic-assisted absorption in a batch system has shown significant enhancement forCO2 removal. Nevertheless, its performance in continuous mode has yet to be studied. A novel continuoushigh frequency ultrasonic contactor system for CO2 capture has been developed to study the effect of gasflow rate (15–25 SLPM), liquidflow rate (0.1–0.5 SLPM), pressure (10–50 bar) and voltage (0–30 V) on theabsorption performance. A validated quadratic model was developed, and the optimum condition wasidentified using central composite design coupled with response surface methodology. Based on theresults, current system demonstrated better absorption performance as compared to other contactors.
