Abstract

Biogas production from the anaerobic digestion of juice in an ethanol production plant is maximized by mixing a juice containing thin stillage and/or water with a concentrated syrup prior to the anaerobic digestion. The juice then can be mixed with a biomass such as corn meal and enzymes to form a slurry suitable for fermentation. Sufficient syrup is mixed into the juice to provide a BOD concentration in the juice between 100,000 and 150,000 ppm. Enough biogas can be produced to supply enough energy to meet all of the boiler steam production/distillation energy/electrical generation demands for the ethanal production plant with some excess biogas left over for other uses.
