Flooding velocities in packed towers

For additional information and methods for estimating pressure drop and flooding velocities in packed towers, see R. H. Perry and D. Green, Chemical Engineers Handbook, 6th ed., Sect. 18, McGraw-Hill Book Company, New York, 1984. 

Flooding velocities in packed towers. If the flow rate of either the dispersed phase or the continuous phase is held constant and that of the other phase gradually increased, a point is reached where the dispersed phase coalesces, the holdup of that phase increases, and finally both phases leave together through the continuous-phase outlet. The effect, like the corresponding action in an absorption column,...
