Anaerobic fermentation is carried in a bioreactor where glucose (C6H12O6) is digested to form the
products ethanol (C2H5OH) and propenoic acid (C2H3CO2H). The product stream is analyzed and
found to contain 96.5 mole % water, 1.34 mole % C2H5OH, 0.79 mole % C2H3CO2H, 1.12 mole
% CO2 and 0.25 mole % C6H12O6. Given the specific gravity of ethanol is 0.789.
a. Calculate the mass fraction of each compound and the average molecular weight of the
product stream mixture.
b. Determine the total mass and molar flow rates of the product stream if the production rate
of ethanol is 160 L/day
