For optimizing an CO2 absorption operation using bubbling column, 82 types of liquid jet flow configurations have been developed. The advantages of these configurations are generated an gas entrainment by suction of nozzle and the gas dispersed throughout the bulk of liquid by the formation of bubble clouds. The configurations were designed based on point of the all nozzles by the position and the inclined liquid jets are ejected The performances of all configurations have been examined for selecting by hydrodynamic tested with holdup gas and gas entrainment rate. The results showed that the configurations of liquid jet flow gived an significant effects on hydrodynamics and absorption aspecs, generally the good configurations selectd had hold-up gas in the range of 0.55-0.6 and the ratio of gas entrainment rate to the liquid rate on the range of 1.3-1.8. The result of absorption tests showed that CO2 concentration can be reduced into 0.01%-0.07% less than five minutes and the absorption should be proceeded with the chemical reaction due to the operations prolonged up to 10 menit, no indication of CO2 desorption process. The bubbles generated in the column showed that the range of bubble diameter (0.00097-0.00184) mm was more dominant.
