A theoretical model for volumetric mass transfer coefficients in bubble columns has been developed. It is based on Higbie's penetration theory and Kolmogoroff's theory of isotropic turbulence. The capability of the proposed model is discussed in the light of experimental data obtained from a 40-L bu
Gas hold-up and liquid phase axial dispersion coefficient have been measured in water filled bubble columns of 5.08, 14.0 and 29sOcm dia. as a function of the superficial gas velocity. From the gas hold-up measurements the following relationship between the relative velocity between gas and liquid,
