Axial dispersion in a reciprocating plate extraction column Journal Articles

abstract

• AbstractAxial dispersion coefficients have been measured in the continuous phase of a 5 cm diameter reciprocating plate extraction column. The measurements were made by observing the course of an instantaneous chemical reaction between acid and base in the continuous phase, using phenolphthalein as indicator. The data for single‐phase operation have been correlated in terms of amplitude and frequency of reciprocation, and spacing between plates. A similar correlation applies for liquid‐liquid operation under intense agitation. At low agitation rates, and for gas‐liquid operation, the dispersion coefficient depends strongly on the flow rate of dispersed phase.
