ABSTRACT

Separation/concentration of different solutes, such as metals, amino acids, etc, has been studied using Non-Dispersive Extraction in hollow fiber modules (NDX). This technology combines some properties of the solvent extraction processes with classical membrane processes, wich allows a better control of the separation step. This work present five differents approaches to the mathematical modelling of this type of systems. The selection of the appropriate method for the modelling of the NDSX of L-Phenylalanine with Aliquat 336, in a batch process, is discussed. It is not neccessary to use the fundamental model to get a good agreement between simulated and experimental results.
