Abstract

Bubble columns are widely used in various industrial processes such as wastewater treatment, fermentation, and gas-liquid reactions due to their simplicity and effectiveness in mass transfer operations. In this study, we investigate the influence of gas holdup and gas velocity on the volumetric mass transfer coefficient in a bubble column reactor. The volumetric mass transfer coefficient is a critical parameter that affects the efficiency of gas-liquid mass transfer processes. Through experimental analysis and computational modeling, we systematically examine the relationship between gas holdup, gas velocity, and the volumetric mass transfer coefficient. In this study, volumetric mass transfer coefficient kL.a was calculated using air in water. The data obtained are in the range of superficial gas velocity (0.03-0.2398) m/s for air water system. The experiments were carried out using 0.1 m column diameter with 2 mm hole diameter and 79 holes gas distributor. From the experimental data it was found that kL.a increased with increasing of gas holdup and increasing of superficial gas velocity.
