Separation Performance of Polymer Membranes for Organic Solvent Mixtures

Abstract

The current investigation directs the focus at the performance of SRNF membranes for the separation of organic solvent mixtures without dissolved species. A correlation between operating parameters (temperature, pressure) and differences in separation performance (fluxes, retention) for commercially available solvent stable nanofiltration membranes of different materials is shown. The membranes are applied in laboratory tests to separate different compositions of organic solvent mixtures. The experiments are conducted over weeks to ensure the constancy of the membranes and respectively the obtained data.
