Hybrid and Novel Processes I – 1 – Keynote Monday July 14, 2:15 PM-3:00 PM, Kaua’i Scaleable Membrane Separations for the Lignocellulosic-to-Ethanol Biorefinery? J. Pellegrino (Speaker), University of Colorado, Boulder, CO, USA, john.pellegrino@colorado.edu K. Colyar, University of Colorado, Boulder, CO, USA M. Gutierrez-Padilla, University of Colorado, Boulder, CO, USA J. Hettenhaus, cea Inc., Charlotte, NC, USA D. Schell, National Renewable Energy Laboratory, Golden, CO, USA There are many challenges to realizing a significant biomass-to-fuels industry based on lignocellulosic feedstocks in the US. One of the significant issues is how to economically address highly distributed, low density feedstock supplies that arise from agricultural (such as, corn stover) and forestry waste material. In addition, ways to recover and recycle fertilizer micronutrients (inculcated wthin the biomass) back to the fields, and bring the farming community further along the value chain, are all important criteria for successful growth of this important industry. To these ends, we will present a brief overview of the opportunities for membrane processes within the lignocellulosic biorefinery and ways that these processes may potentially mitigate the economic penalties associated with small scale plants. We will report bench-scale studies on leaching of micronutrients from stored wet stover, co-harvested with the corn in a cooperative, and the recovery and recycle of fertilizer anions and cations, as well as the water. We will also present the broad results from several other membrane processes that recover and recycle water, and/or fractionate by-products from this stover as it undergoes pre-hydrolysis using a novel reactor designed for small scale processing. And from the ethanol fuel product side, we have performed separation studies on the removal of small organic molecules, which provide inhibition of the fermentative organisms, in order to recycle water back to the ethanol fermentor from the beer column. A variety of commercial membranes have been considered for all these operations, and initial figures-of-merit have been obtained and will be discussed within the context of desirable improvements in materials and/or process configurations.
Hybrid and Novel Processes I – 2 Monday July 14, 3:00 PM-3:30 PM, Kaua’i Reducing the Energy Demand of Bio-Ethanol through Salt-Extractive Distillation and Electrodialysis P. Pfromm (Speaker), Kansas State University, Manhattan, KS, USA, pfromm@ksu.edu M. Hussain, Kansas State University, Manhattan, KS, USA Bio-ethanol from corn currently consumes about 34,000 BTU in form of natural gas to produce one gallon of ethanol representing 76,000 BTU as lower heating value (U.S. industrial practice data, 2007). Separating ethanol from water consumes about 40% of the natural gas demand cited above. Saline extractive distillation of alcohol-water mixtures and fermentation broth has been considered elsewhere and fairly comprehensive experimental data, thermodynamic data, and simulations are available. Potentially very significant energy savings and process simplifications have been found. However, the recovery and recycling of the salt used to facilitate distillation has not been addressed. Electrodialysis is uniquely suited for salt recovery from the saline extractive distillation column bottoms since salt is selectively removed from the solution (no water is evaporated) and the electrodialysis membranes and overall fluid handling are tolerant to fermentation broth and even to entrained particulate matter. Concepts, modeling, and experimental data for electrodialysis-enabled salt extractive ethanol distillation will be shown. Aqueous/aqueous and aqueous/ethanol electrodialysis will be discussed.
