Ebook: Bioethanol from Starch. Process Simulation Tutorial on PRO II/8.2

Washington State University, April 21, 2010. - 23 p.
The process model is developed using PRO II/8,2
However, before creating a model in PRO II, the conversion rate from starch to glucose and glucose to ethanol need to be determined. The conversion rate for starch is based on the following journal article: Parameter Estimation for Simultaneous Saccharification and Fermentation of Food Waste into Ethanol Using Matlab Simulink by Rebecca Anne Davis. The conversion rate is based on 90 g/l of starch that produces 80 g/l of glucose which equates to 89% conversion rate. Next, to find the conversion rate from glucose to ethanol MATLAB will be used. This is done by simulating the growth kinetics of ethanol production from glucose using the rate equations listed below. The initial concentration of glucose is based on the above article.ContentsIntroduction to the project
