P11-75 The gas-phase reversible reaction AZB is carried out under high pressure in a packed-bed reactor with pressure drop. The feed consists of both inerts I and Species A with the ratio of inerts to the species A being 2 to 1. The entering molar flow rate of A is 5 mol/min at a temperature of 300 K and a concentration of 2 mol/dm? Work this problem in terms of volume. Hint: V = W/p... =p Additional information: FAo = 5.0 mol/min T, - 300 K C = 2 mol/dm T. - 300 K G = 2 Co k, = 0.1 min at 300 K C18 cal/mol/K Ua = 150 cal/dm/min/K - 160 cal/mol/K T. = 300 K E = 10,000 cal/mol V = 40 dm AH. --20,000 cal/mol 0p, -0.02 dm Ke = 1,000 at 300K Coolant y = 160 cal/mol/K wie = 50 mol/min Ps= 1.2 kg/dm' tas = 20cal/mol/K (a) Adiabatic Operation. Plot X. X. p. T. and the rate of disappearance as a function of V up to V = 40 dm'. Explain why the curves look the way they do. (b) Vary the ratio of inerts to A (oso, s10) and the entering temperature, and describe what you find. (c) Plot the heat that must be removed along the reactor (O vs. 1) to maintain isothermal operation. Part(e) is "C" level of difficulty. We will continue this problem in Chapter 12
