P6-8c (Membrane reactor) The first-order, gas-phase, reversible reaction AFB+2C is taking place in a membrane reactor. Pure A enters the reactor, and B diffuses out through the membrane. Unfortunately, a small amount of the reactant A also diffuses through the membrane. (a) Plot and analyze the flow rates of A, B, and C and the conversion X down the reactor, as well as the flow rates of A and B through the membrane. (b) Next, compare the conversion profiles in a conventional PFR with those of a membrane reactor from part (a). What generalizations can you make? (c) Would the conversion of A be greater or smaller if C were diffusing out instead of B? (d) Discuss qualitatively how your curves would change if the temperature were increased signifi- cantly or decreased significantly for an exothermic reaction. Repeat the discussion for an endot- hermic reaction. Additional information: k = 10 min-1 Kc = 0.01 mol/dm = 1 min-1 = 40 min-1 FAO 100 mol/min VO = 100 dm3/min V. = 20 dm3 reactor
