Bubble column reactor with a draft tube is often used as a chemical reactor to promote the circulation of liquid in the reactor. When this circulation of liquid promotes the dispersion of solid particles, a column of this type is called as a pachuca tank which is used for leaching of solid. However, studies on the quantitative treatment of the circulation of liquid are scarce. In this paper a general method of prediction for gas lift action was investigated. The gas hold up and slip velocity of bubble swarms in tube were quantitatively correlated by considering the effects of tube diameter, tube length, and gas distributors. By using the correlations for the slip velocity and the gas hold up, the liquid velocity in the draft tube was predicted and these values were in good agreement with experimental values.
