Abstract
A theoretical analysis of the liquid holdup in the countercurrent-flow rotating packed bed has been developed. It is based on liquid film on a rotating disk in the presence of the gas, with the assumption that the rotating packed bed may be modelled as n layers of hypothetical rotating disks stacked together. Agreement between the predicted values of the liquid holdup and the experimental values was quite good. With this model, the liquid holdup can be estimated in the countercurrent-flow rotating packed bed with data of pressure drop. Furthermore, a correlation for the liquid holdup in the conventional packed bed was extended and modified to estimate that in the countercurrent-flow rotating packed bed.
