Abstract
Gas-phase dispersion in bubble columns of 0.5 and 0.2 m diameter was investigated experimentally by the impulse response method at superficial gas velocities in the range 0.029–0.456 m/s. Based on the recirculation theory of bubble columns, the expression for the axial dispersion coefficient of the gas phase was found to be E G = (180/α) U G D 3 2 T . The experimental results in water bubble columns were quantitatively described by this equation with the proportional constant α = 9. At gas velocities higher than 0.1 m/s, the gas-phase dispersion was suppressed by the insertion of perforated plates with a free area of 44%.
