TLDR
In this article, the mass transfer resistances due to the tube-side fluid, the hollow fiber wall (membrane), and the shell side fluid were determined for runs in which the solvent was held stagnant on the shell-side.Abstract:
Liquid-liquid extraction operations were conducted in a hollow fiber mass transfer device using two systems: phenol/water vs. n-octanol and phenol/hexane vs. water. Individual mass transfer resistances due to the tube-side fluid, the hollow fiber wall (membrane), and the shell-side fluid were determined for runs in which the solvent was held stagnant on the shell-side. Countercurrent flow runs with moving solvent were conducted to show that the degree of extraction rises steadily as the solvent-to-raffinate ratio increases. Factors affecting the mass transfer resistances in this type of device are discussed, and the advantages of hollow fiber units over conventional mixer-settler units are pointed out.read more

Liquid-liquid extractions with microporous hollow fibers
TL;DR: In this paper, it was shown that extractions in hollow fibers will be fastest when the fibers are wet by the fluid in which the solute is more soluble, and when fiber modules are a sound inexpensive alternative to centrifugal extractors.

Solvent extraction of phenol from aqueous solution in a hollow fiber device
David O. Cooney,Chin-Lern Jin +1 more
TL;DR: In this article, a hollow fiber "shell and tube bundle" unit was used for the extraction of phenol from aqueous solution, where various solvents (n-hexanol, n-octanol, ii-decanol, methyl isobutyl ketone, and n-butyl acetate) were used on the shell side; the phenol solution was pumped through the tube side.
