QUESTION 3 130 marks] A client has engaged your consulting company to perform the approximate design of a reactor system. Your manager has asked you to base the design on the set of heuristics (1-13) below. The reaction is liquid-phase and to be conducted in a series of FOUR continuous stirred tank reactors (CSTRs). The feed flowrate is 35 m/h and it is known that a total residence time of 190 minutes is needed if the reaction is conducted at 50C, but your manager wishes you to design for a reaction temperature of 60'C. The reaction is moderately endothermic, with heating to be supplied by immersed heat transfer coils. For your design, please detail the following: (a) The volume of each reactor vessel. (10 marks] (b) The dimensions (height and diameter) of each reactor vessel. [8 marks] (c) The combined stirrer power requirement for the set of reactors. [5 marks] In your answers above, please note the heuristics used, as well as the assumptions that you made and any justifications for them. (d) Briefly explain which Hysys model(s) you would use to simulate the reactor system. Consider two cases: known reaction kinetics, and the reaction kinetics being unknown. [4 marks] (e) Your manager asked you to use four reactor vessels in series for the design, but five vessels would be a reasonable alternative. Very briefly, what are some arguments to consider when deciding to select four versus five vessels?
