Ethanol Separation for Biofuels

Process Monitoring/Control/Optimization



Rob is currently involved in projects in three different areas.  The first involves collaboration with the technical staff at Fractionation Research, Inc. (FRI).  Located on the OSU campus, FRI is a non-profit research consortium supported by the largest petroleum and petrochemical companies in the world.  FRI is recognized globally as the gold-standard for industrial-scale distillation research.  Rob and his students are working with FRI to develop new models (empirical and first-principles) to predict the efficiency of valve trays.  Rob’s team has access to over 50 years of FRI experimental data.  Although most of the results will remain proprietary, FRI-approved portions of the work will be made public.


Rob is extending his distillation focus with researchers in OSU’s School of Biosystems and Agricultural Engineering (BAE) in the area of biofuels.  Rob’s group is currently preparing to build a farm-scale demonstration system to perform dewatering of ethanol produced from sweet sorghum.  The system includes two 12-inch diameter distillation columns to produce a 95 % ethanol fuel product.  Mol sieves and pervaporation will be evaluated for final dewatering to a 99.5 % product.  “Sorganol” represents an alternative to starch (e.g., corn) and cellulosic (e.g., switchgrass) based methods of producing bioethanol.


The third project involves investigation of appropriate methods to determine economic values of intermediate product streams used in the objective function of APC (advanced process control) multivariable controllers.  The work involves a combination of control and LP optimization concepts at the interface between theory and practice.
