2,3-butanediol (BDO) is a common component in fermentation broths present in low concentrations. Recovery/separation of 2,3-butanediol poses many challenges due to inherent limitations such as its high affinity with water and issues with energy-intensive evaporation and multi-stage distillation. BDO separations approaches have been under development by the Separations Consortium for several years. A team representing Argonne, Berkeley, Los Alamos, NREL, Oak Ridge and Pacific Northwest National Labs including Ramesh Bhave, Syed Islam, Shailesh Dangwal, Gregg Beckham, Ning Sun, Eric Tan, Bill Kubic, Vanda Glezakou, Difan Zhang, Jian Liu presented these slides at DOE Project Peer Review.
