Problem 3: The elementary irreversible liquid-phase reaction A+B C is carried out adiabatically in a flow reactor at steady state. An equimolar feed of A and B enters at 27C; the volumetric flow rate equals 2 dm /s; and C = 0.1 kmol/dm. a. Calculate the adiabatic PFR and CSTR volumes necessary to achieve 85% conversion Explain any similarities/differences between your answers. b. What is the maximum inlet temperature one could have such that the boiling point of the liquid (550 K) would not be exceeded even at complete conversion? c. Using MATLAB or other numerical software, plot the conversion and temperature as a function of PFR volume (i.e., distance along the length of the reactor). d. Calculate the conversion which can be achieved in a 500 dm3 CSTR. Additional information HA (273K) --20 kcal/mol HB (273 K)=-15 kcal/mol HC (273 K)=-41 kcal/mol Cp,A = Cp, B = 15 cal/mol-K Cp,C = 30 cal/mol-K k=0.01 dm'/(mol-sec) at 300 K E = 10,000 cal/mol
