QUESTION 2. (30 Marks). A chemical engineer is exploring to open his own microbrewery based on a novel continuous steady-state process. In this continuous process, the beer moves through a series of stirred vessels one of which is the fermenter which delivers 200 000 L/month of beer. The fermentation fits well the Monod equation and operates in cycles of 108 hours. Each cycle includes; 1) loading the substrate and nutrients for 2 hours; 2) to process the nutrients for 100 hours, and 3) to unload the beer and fermentation products for 2 hours. This is followed by the next new cycle. The following data are to be determined to assess the viability of the business venture: A) Mass balance within the battery of the fermenter B) Basic PFD around the fermenter. Residence time of the substrate in each fermentation cycle. D) The rate of microbial growth (yeast) during fermentation to alcohol. E) The half-velocity constant K, when the substrate S= 2 mg/L. F) The Volume of the fermenter in m3.
