(25 points) Acetic Acid is to be generated in a reactor by the addition of sulfuric acid to calcium acetate according to: Ca(COOCH3)2+H2SO4CaSO4+2(CH3COOH) The sulfuric acid fed to the reactor is 10% in excess. The single pass conversion of the reactor is 90%. The unused calcium acetate and sulfuric acid are separated from the reaction products and are recycled back to the process. The acetic acid is separated from the reaction products and sold. The atomic weights are Ca=40,S=32,C=12,H=1,O=16. (a) Draw a diagram for the process. Label all the streams. (b) Calculate the total amount (in moles) of the recycle stream per hour based on 1000lb/h of calcium acetate in the initial feed to the process. (c) Calculate the pounds of acetic acid manufactured per hour. 2. (25 points) In the anaerobic fermentation of grain, the yeast Saccharomyces cerevisiae digests glucose from plants to form the product ethanol and propanoic acid by the following reactions: C6H12O6(glucose)C6H12O6..2C2H5OH(ethanol)+2CO2C2H3CO2H(p.acid)+2H2O A reactor is charged with 4Kg of a 12mol% glucose/water solution. After fermentation 120 grams of carbon dioxide are produced together with 90 grams of unreacted glucose, (a) Draw and label a flow diagram. (b) Set up stoichiometric tables based on extent of reaction for both reactions. (c) Calculate the molar flow rates of each component in the product stream (d) Calculate the mass percentage of ethyl alcohol leaving the reactor
