%X The Nano-bubble process is a novel effective technology for CO 2 removal. Its advantages are their high specific area and stagnation in the liquid phase, which increase the gas dissolution. This study proposes the application of system using swirling jet flow method for the CO 2 absorption from mixture gas consisting of 60%v/v CO 2 and 40%v/v N 2 at 1000 ml/min using water as an absorbent. The effects of water temperature and gas/liquid ratio were studied. The results indicate that CO 2 outlet concentrations were in the range of 3.1%-8.6% at gas/liquid ratio of 0.05-0.2 ZLWKDFRQVWDQWLQIORZUDWHRIJDV:KHQWHPSHUDWXUHZDVGHFUHDVHG IURPWRÛ& &2 2 outlet concentrations reduced from 3% to 2% at 20 l/min of water. The CO 2 removal performance could be significantly improved because the decreasing of the temperature increased the viscosity of liquid and residence time of CO 2 bubbles in the column.
