  1. ABE-Fermentation Product recovery optimization during alcohol fermentation Rom AntoniaFriedl Anton arom@mail.zserv.tuwien.ac.at Gefördert bzw. finanziert in der Programmlinie „A3plus“ – vom Bundesministerium für Verkehr, Innovation und Technologie (BMVIT)

  2. ABE-Fermentation Butanol – the next bio fuel The Project: • Investigation of different down streaming processes • Assessment of different membrane materials • On – line down streaming during fermentation process • Simulation in Aspen Plus

  3. ABE-Fermentation Down Streaming in ABE - Fermentation Substrate: wheat bran Fermentation broth: Aqueous solution with 6:3:1 ratio (Butanol:Acetone:Ethanol) Due to product inhibition in-situ butanol recovery is investigated by membrane separation or gas stripping (liquid) (liquid) (vapour)

  4. ABE-Fermentation Vacuum Membrane Distillation vacuum concentrated butanol ABE - broth

  5. ABE - Fermentation

  6. ABE - Fermentation CP – capillary module TP – tubular module The effect of feed concentration and permeate pressure on butanol flux The effect of feed concentration and permeate pressure on selectivity Higher vacuum on permeate site as well as an increasing feed concentration yields higher transmembrane fluxes. Though it results in different selective characteristics.
