Th elementary, irreversible, organic liquid-phase reaction A+B—1C is carried out in a flow reactor. An equal molar feed in A and B enters at 27°C, and the volumetric flow rate is 2 dm2/s and CAo = 0.1 kmol/m3. Additional information: H; (273K) = -20 kcal/mol, H (273K) = -15 kcal/mol, HE (273 K) = -41 kcal/mol CP = Cp, = 15 cal/mol K Cpe = 30 cal/mol K k = 0.01 at 300 K E = 10,000 cal/mol Ua = 20 cal/m/s/K me = 50g/s To = 450K C = Ical/g/K dm mols The reversible reaction (part (d) of P11-4a) is now carried out in a PFR with a heat exchanger. Plot and then analyze X, X., T, Ta, Q, Qg, and the rate, -ra, for the following cases: (b) Constant heat-exchanger temperature Ta (c) Co-current heat exchanger Ta (Ans.: At V = 10 m3 then X = 0.36 and T = 442 K) (d) Countercurrent heat exchanger Ta (Ans.: At V = 10 m then X = 0.364 and T = 450 K) (e) Adiabatic operation (1) Make a table comparing all your results (e.g., X, Xe, T, Ta). Write a paragraph describing what you find.
