Use the data in Problem P11-4A for the following reaction. Th elementary, irreversible, organic liquid-phase reaction is carried out in a flow reactor. An equal molar feed in A and B enters at 27ºC, and the volumetric flow rate is 2 dm3/s and CA0 = 0.1 kmol/m3. Additional information: (273 K) = 20 kcal/mol, (273 K) = 15 kcal/mol, (273 K) = 41 kcal/mol = = 15 cal/mol K = 30 cal/mol K k = 0.01 at 300 K E = 10,000 cal/mol (a) Calculate the conversion when the reaction is carried out adiabatically in one 500-dm3 CSTR and then compare the results with the two adiabatic 250-dm3 CSTRs in series. The reversible reaction (part (d) of P11-4A) is now carried out in a PFR with a heat exchanger. Plot and then analyze X, Xe, T, Ta, Qr, 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 m3 then X = 0.364 and T = 450 K)
