Gas holdup from the free surface of liquids subjected to a vertically vibrating plate
Gas holdup is an important factor in the various technological processes involving the interaction between liquid and gaseous systems. The goal of the present research is to study the effect of vibration parameters and plate design on the gas holdup efficiency in a vibrating plate column. The gas bubbles were generated by the vibrating plate, which was sufficiently close to the liquid surface. An analytical model for the calculation of the gas holdup was developed. A device for the introduction of the gas and the vertical vibration of the liquid was designed and used in this research. The experimental data obtained are in good agreement with the theoretical calculations. The results show the possibility of enhancing the gas holdup by changing the vibration parameters and optimizing the vibrating plate unit design parameters.
