Problem 4: The elementary irreversible liquid-phase reaction A + 2B>C is to be carried out in a semibatch reactor in which B is fed to A. The volume of A in the reactor a is 10 dm, the initial concentration of A in the reactor is 5 mol/dm, and the initial temperature in the reactor is 27C. Species B is fed at a temperature of 52C and a concentration of 4 M. It is desired to obtain at least 80% conversion of A in as short time as possible, but at the same time the temperature of the reactor must not rise above 130C. You should try to make approximately 120 mol of C in a 24 hr day allowing for 30 minutes to empty and fill the reactor between each a a batch. The coolant flowrate through the reactor is 2000 mol/min. There is a heat exchanger in the reactor. (a) What volumetric feed rate (dm3/min) do you recommend? (b) How would your answer or strategy change if the maximum coolant rate dropped to 200 mol/min? To 20 mol/min? =- = = Additional information: AHR =-55,000 cal/mol A pA = 35 cal/mol.K, CpB = 20 cal/mol.K, Cpc = 75 cal/mol.K dm k=0.0005 at 27C with E= 8000 cal/mol mol2.min cal UA = 500 with Ta = 17C min.K = = Cp (coolant) = 18 cal/ mol.K
