Simulation of Biogas Production Using Rigorous Fermentation Model in Aspen Plus

This presentation is to demonstrate how to simulate manure to biogas conversion in an anaerobic batch fermentation tank, using biocomponents and the built-in fermentation unit operation in Aspen Plus. The fermentation kinetics are modeled in a single reactor in order to represent wastewater treatment processes involving mixed cultures of micro-organisms. The fermentation model provides sufficient flexibility to closely describe real-world phenomena and capable of accurately predicting gas yield and production rates. It can be used to help process engineers have a deeper understanding and insight for the manure to biogas conversion process, and lead to ideas for process improvement and optimization.
