Three fed- batch reactors each with net volume of 300,000 liters has been designed to produce AHA (99.70% alc v/v). Data: Fermentation efficiency= 85% based on fermentable sugar. Distillation Eff=97%; RS=94.5% V/V alc; Dehydration=99%; Percent alcohol in beer is 8.5%; Fermentable sugar in molasses = 45%; SG of molasses=1.44; Cycle time for each reactor = 36 h 1. What is the tons molasses required (nearest value)? 2. What is the volume of beer distilled? 3. What is the volume of mixing water required? 4. What is the wastewater/AHA ratio if fermentation efficiency drops to 80%?

Question
Three fed- batch reactors each with net volume of 300,000 liters has been designed to produce AHA (99.70% alc v/v).
Data: Fermentation efficiency= 85% based on fermentable sugar. Distillation Eff=97%; RS=94.5% V/V alc; Dehydration=99%; Percent alcohol in beer is 8.5%; Fermentable sugar in molasses = 45%; SG of molasses=1.44; Cycle time for each reactor = 36 h
1. What is the tons molasses required (nearest value)?
2. What is the volume of beer distilled?
3. What is the volume of mixing water required?
4. What is the wastewater/AHA ratio if fermentation efficiency drops to 80%?
