C6H1206 (s) +1.5 O2(g) + NH3(g) CsH9N04 (1) + 3 H20 (1) + CO2(g) AH,=-945 kJ The liquid-phase inlet stream contains water and glucose; the mass fraction of glucose is 0.05. The liquid phase inlet total flow rate is 4.5 kg/min. The mass flow rate of the unreacted glucose in the outlet stream is 22.5 g/min. Ammonia and oxygen enters in a separate gas phase stream. Carbon dioxide as well as excess ammonia and oxygen leave in a second gas phase product stream (see Figure below). The system is operated continuously and at steady-state. The inlet streams are at 25C, while the reactor and the output streams are at 35C. Assume that all the gases behave ideally. Output gas, 35C, 1 atm Input gas, 25C, 1 atm 2.5 mols O2/min 1.5 mols NH3/min Bioreactor 0.8125 mols Oy/min 0.375 mols NH3/min 1.125 mols CO2/min Liquid Feed, 25C, 1 atm 4.5 kg/min 0.05 kg C6H12O6/kg 0.95 kg H2O/kg Output solution, 35C, 1 atm 1.125 mols CsH.NO/min 22.5 g C6H120/min ni mols H2O/min Specific heats (Cp, in J/ mol K): C6H1206 (8) = 208, CsH NO4 (1) = 175 a) What is the extent of reaction? (Ans: &= 1.125) b) Solve for the molar flowrate of water in the output solution, in mols/min. (Ans: ni=240.9 mols H2O/min) c) Make an Enthalpy Table for the system. Identify your reference states for the Table. d) Is heat added or removed from the Bioreactor? At what rate, in kJ/min
