Rotating-disc contactor-RDC

K. Liquid-liquid extraction in Rotating-disc contactor (RDC)... 

For example, to calculate the dispersion coefficient for a Rotating Disc Contactor (RDC), given in [6.24],... 

Usually, practical design correlations for and or the characteristic velocity v are directly derived from experimental data. For example, in an Rotating Disc Contactor (RDC), in the operating range of interest, the velocity limit of the dispersed phase at the flooding point is according to Strobel and Salzer [6.30]...

There are three wo well known types of column that can be used for continuous countercurrent liquid/liquid contacting rotating disc contactors (RDC) and pulsed packed columns (PPC) (these are not to be confused with three-phase packed coplumn reactors, operated under pulsed flow conditions, see section 4.7.2.3).

RDC Column. The rotating disc contactor (Fig. 19) provides for redispersion by a series of discs along the shaft, combined with a series of fixed stators. Vortices are formed in each compartment, and the shear of the fluid against the rotor or stator causes the drop breakup. In many instances.
