✦ Synopsis

Llqmd-hqmd mass transfer characterlstlcs have been determined for smgle freely nsmg drops and swarms of drops m both packed and Oldshue-Rushton column extractors, usmg the systems toluene-acetonewater and MIBK-acetIc acid-water, In an attempt to elucidate the relative importance of any special mass transfer mterfacml mstabdlty effects, under dlffenng hydrodynamic condrtlons of operation ExperimentsHy determmed values of the overall coefficient of mass transfer, corrected for axml mtxmg, were compared with theoretIcal predictions Although showmg some scatter, there does appear to be some evidence for an effect of the solute on the rate of mass transfer Under condtlons of actual column operation however, this effect 1s negbglble, compared to the dominant effect of drop-drop mteractton on the column hydrodynamics and especially on mean drop size, as reported previously m Parts I and II of this study tNTRODUCTtON Sternhng and Scnven[l] have analysed the condttions,
