   The elementary reversible organic liquid-phase reaction.

   

   is carried out in a flow reactor. An equal molar feed in A and B enters at 47°C, and the volumetric rate is 2 dm³/s and C_A0 = 0.1 mol/dm³.

   1. For adiabatic operation, plot X, X_e and T of the PFR profiles up to a volume of 100 dm³.
   2. Repeat (a) when a heat exchanger is added, Ua = 0.8 cal/dm³/s/K, and the coolant temperature is constant at T_a = 320 K.
   3. Repeat (b) for a co-current heat exchanger for a coolant flow rate of 50 g/s and C_Pe = 1 cal/g • K, and in inlet coolant temperature of T_a0 = 320 K. Also plot T_a versus volume.
   4. Repeat (c) for counter current coolant flow.
   5. Compare your answers to (a) through (d) and describe what you find. What generalizations can you make?
   6. Vary the coolant rate (1 < < 1,000 g/s) for (c) and (d) and describe what you find.
   7. Repeat (a) (b) (c)and (d) when the reaction is endothermic with ΔH_Rx = 6,000 cal/mol but with T₀ = 400K and T_a0 = 450K.
