Modeling, simulating and optimizing the anaerobic digestion of swine manure
AbstractA detailed dynamic model of the anaerobic digestion process is validated using recently acquired data for steady state and dynamic digester operation with swine manure. The validated model is used to investigate the effects of loading frequency, differences in digester design when liters of methane per liter of digester or liters of methane per gram of Volatile Solids added is maximized, and the sensitivity of gas production to changes in digester inputs. The results indicate that changes in the frequency of loading do not significantly affect digester performance. It is also found that total gas production is insensitive to whether liters of methane per liter of digester or measure digester performance. Finally, it is found that gas production is sensitive to changes in the influent Volatile Solids concentration and the retention time, but is relatively insensitive to changes in the digester temperature.
