High-flux POMS organophilic pervaporation for ABE recovery applied in fed-batch and continuous set-ups
Abstract(#br)The performance of fed-batch and continuous ABE fermentations integrated with organophilic pervaporation was thoroughly tested. Poly(octyl methyl siloxane) (POMS) based pervaporation membranes were applied during fermentation and compared to the performance of polydimethylsiloxane (PDMS) based membranes. The performance of POMS based pervaporation membranes was superior both in terms of flux, separation factor and pervaporation separation index.
