TLDR
In this paper, differentially protein extractions were measured with two types of extractants: inverted micelles and two-phase aqueous systems, and the results showed that hollow-fiber extractions are substantially faster than those possible in conventional equipment.Abstract:
Differential protein extractions were measured with two types of extractants: inverted micelles and two-phase aqueous systems. The results show that hollow-fiber extractions are substantially faster than those possible in conventional equipment. The extractions are not compromised by loading or flooding because the flows of extractant and raffinate are almost completely independent. Mass transfer coefficients inferred from the measurements both support and extend design equations for these contactors.read more

TL;DR: A general review of hollow fiber membrane contactors, including operating principles, relevant mathematics, and applications, is provided in this paper, where a number of membrane module geometries are possible, hollow fiber modules have received the most attention.

Hollow-fiber membrane contactors
TL;DR: In this article, a liquid sorbent contacts the gas mixture along asymmetric hollow-fiber membranes that enable transfer of the carbon dioxide from a gas mixture to the liquid carbon dioxide.

Mass transfer in various hollow fiber geometries
TL;DR: For the special case of flow within the fibers, the slight polydispersity of the hollow fibers causing this channelling can be used to predict deviation from the Leveque limit as discussed by the authors.

The effect of shell side hydrodynamics on the performance of axial flow hollow fibre modules
TL;DR: Fluid flow and mass transfer experiments have been performed on axial flow hollow fiber modules of varying packing density (32 to 76%). Shell-side pressure drop was found to be proportional to (flowrate)n, where n varied from about 1.1 at high packing density to 1.5 at low packing density, for shellside Reynolds numbers as mentioned in this paper.

Liquid membrane technology for the separation of racemic mixtures
TL;DR: In this article, a new process has been developed to separate enantiomeric mixtures, based on the combination of a countercurrent fractionation and liquid membrane technology, and experiments have been performed in a bench scale unit, in which optical purities of 99% plus for both enantiomers have been obtained.
