Exercise 2

Consider the batch growth curve in Fig. 9.4 and the corresponding plots of dX/dt vs. X and dP/dt
vs. P. (Fig. 9.7). You are asked to design a two-stage reactor system with continuous flow that
will produce product P at a concentration of 0.55 g/l. You wish to minimize total reactor volume.
For a flow rate of 1000 l/h what size reactors (and in what order) would you recommend?
