Abstract
Two-phase experiments have been carried out using organic liquids with a surfactant and air in a bubble column 30 [cm] inside diameter and 3 [m] tall. Under the presence of the surfactant, two distinct regions are observed: a bubbling region in the lower part, and a froth zone in the upper part of the column. Intrinsic gas holdup were measured in each region. Results showed that intrinsic gas holdup did not vary significantly with surfactant concentration. However, the position of the limiting surface separating the two regions varied considerably with surfactant concentration, thus affecting strongly the overall gas holdup. Based on these facts, correlations for intrinsic and overall gas holdup have been proposed.
