Flooding Velocity Maximum flow through a countercurrent extractor is limited by the flooding velocity. See Hydrodynamics of Column Extractors lor a general discussion of flooding mechanisms. Because of the many possible causes of flooding, published data and... [Pg.1752]

The modelling approach to multistage countercurrent equilibrium extraction cascades, based on a mass transfer rate term as shown in Section 1.4, can therefore usefully be applied to such types of extractor column. The magnitude of the mass transfer capacity coefficient term, now used in the model equations, must however be a realistic value corresponding to the hydrodynamic conditions, actually existing within the column and, of course, will be substantially less than that leading to an equilibrium condition.
