Abstract
In order to improve the performance of a countercurrent bubble column, radial variations of the gas holdup and mean holdups were investigated in a 0.160m i.d. bubble column using electrical resistance tomography with two axial locations (Plane 1 and Plane 2). In all the experiments tap water was the liquid phase and air was the gas phase. The superficial gas velocity was varied from 0.02 to 0.25 m/s, and the liquid velocity varied from 0 to 0.01 m/s. The effect of liquid velocity on the mean holdup and radial gas holdup distribution is discussed. The experimental results show that the liquid velocity slightly influences the mean holdup and radial holdup distribution under the operating condition. An empirical correlation for the centreline gas holdup is obtained based on the effects of gas velocity, liquid velocity, and ratio of axial height to column diameter.th World Congress on Industrial Process Tomography, Bergen, Norway.
