P11-4 (a-c and 1) LLLLLLLLLLLLLS In part f, the reactor is also operated adiabatically P11-4, OEQ (Old Exam Question). The elementary, irreversible, organic liquid-phase reaction A-B-C is carried out adiabatically in a flow reactor. An equal molar feed in A and B enters at 27C and the volumetric flow rate is 2 dms and Co - 0.1 kmol/m Additional information: Hz (273K) - - 20 kcal/mol, H; (273K) = -15 kcal/mol. HE(273K) = - 41 kcal/mol Cp, - Cp, - 15 cal/mol K Ge - 30 cal/mol K k -0.01 dm at 300 K E = 10000 cal/mol mols PER PFR Plot and then analyze the conversion and temperature as a function of PFR volume up to where x = 0.85. Describe the trends b. What is the maximum inlet temperature one could have so that the boiling point of the liquid (550 K) would not be exceeded even for complete conversion? c. Plot the heat that must be removed along the reactor (vs. 1) to maintain isothermal operation d. Plot and then analyze the conversion and temperature profiles up to a PFR reactor volume of 10 dm' for the case when the reaction is reversible with K - 10 m /mol at 450 K. Plot the equilibrium conversion profile. How are the trends different than part (a)? (Ans: When V - 10 dm' then x - 0.0051, X.-0517) CSTR .. What is the CSTR volume necessary to achieve 90% conversion BR t. The reaction is next carried out in a 25 dm batch reactor charged with No - 10 moles. Plot the number of moles of A N, the conversion and the temperature as a function of time
