Abstrakt

In this paper, a method for CFD modelling of microporous membrane cleaning by supercritical fluid extraction (SFE) is presented. Results of CFD simulations results are shown and compared with experimental data for the process of microporous polypropylene membrane cleaning by SFE in a continuous-flow lab-scale SFE module.
