LIQUID-LIQUID EXTRACTION. PART XIII. THE EFFECT OF PULSE WAVE-FORM AND PLATE GEOMETRY ON THE PERFORMANCE AND THROUGHPUT OF A PULSED COLUMN
Flood-point data have been determined for six solventwater systems using a 3 in. diameter pulsed plate-column. The variables investigated were the plate spacing, plate geometry (i.e. hole-size and percentage free area), and the pulse wave-form. In the latter case, sinusoidal, saw-tooth, and semi-square wave-forms were selected for study. In the absence of an undistributed solute, the data were interpreted in terms of the characteristic velocity which was correlated with the column variables, the physical properties of the system and the pulse characteristics. Mass transfer data were obtained for both directions of transfer using the systems water-toluene and water --butyl acetate with acetone as solute. Overall (H.T.U.) values for a given system were correlated in terms of variations in the interfacial area. (auth)
