Abstract

Axial dispersion performance of a 2-m high 76-mm diameter pilot-scale pulsed solvent extraction column has been studied using two liquid–liquid systems, Alamine 336/isodecanol/Shellsol 2046 (continuous)–tap water (dispersed) and LIX 84/Shellsol 2046 (continuous)–tap water (dispersed). The pulsed column was operated with standard disc and doughnut internals and Tenova pulsed column–kinetics internals using pulsation intensities from 0.005 m/s to 0.025 m/s with polyvinylidene fluoride internal plates of 22.4% open area. The effect of pulsation intensity, dispersed phase velocity, and continuous phase velocity on axial dispersion coefficient have been investigated and compared with the two diff..
