Question 2: Canadia strains can be grown on acetic acid. Biomass is produced in a stirred tank reactor in aerobic culture at 30C with ammonia as nitrogen source and 12.3%(w/w) acetic acid as a substrate (assume a density of the medium of 1g/g ) The biomass contians 5.3% ash, 0.29g biomass is produced for each gram of acetic acid consumed, and no major metabolic products are formed. The stirrer power input is 3.68W/L(1W=1J/S). Production is performed in a volume of 862L. After the batch time of 10.1h, you lose about 4% of the water due to evaporation. Deltha Hv at 30C is 2430.7kJ/kg. The general sttoichiometric equation can be denoted as follows: The equation contains the sum formula of acetic acid anf th elemental cpmosition of Candida utilis: C2H4O2+aO2+bbNH3cCH1.8O0.37N0.19+dCO2+eH2O Ultimately you want to calculate the cooling requirements neglecting sensible heat changes. In the first step, you calculate the oxygen reqiurements. A) Calculation of the oxygen requirements Please depict the ox. req. per batch for this process (unit: kg ) in the following field: Hint: remember, at the end you just need the stoichiometric coefficient for oxygen , converted to mass terms (which is then Yos) to solve this question B) Calculation of the cooling reqiremts: Please depict the cooling req. (Q) for this process (unit: kJ) Interims results: a (mol/mol): MW acetic acid (g/mol) : MW cells (g/mol) : c(mol/mol) : Deltha H evaporated (kJ) : gamma acetic acid: Yos(g/g) nO2(mol): Ws (kJ)
