The gas liquid mass transfer has been studied for a single long bubble, which is kept stationary in the flow by a low and stable flow rate of liquid around it. This study was carried out for a downward flow in small diameter pipe. The mass transfer mechanism is quite complicated because it doesn’t depend only on the physical properties of the gas; but also on the hydrodynamics of the bubble and the liquid film around it. Based on Hgbie’s penetration theory a detailed numerical simulation of the hydrodynamic characteristics of the gas liquid mass transfer in a vertical pipe is developed using the volume of fluid (VOF) method implemented in the commercial software ANSYS Fluent. The simulation is performed using three types of gas, which are nitrogen, oxygen, and carbon dioxide as the gas phase, and water as the liquid one. The results show that the mass transfer of gas increases as the length of the bubble does. For the three types of gas, the mass transfer coefficient increases with the decrease of the gas density. The numerical results are analogous with the experimental ones available in the literature.
