Operating large reactors in industry can be expensive, so a common trick used to reduced costs is to operate multiple CSTRs in series, in which the exit stream of one CSTR is the inlet stream of the next CSTR, as shown in Figure 24.2. Assuming that the. Figure 24.2: Diagram of \(3\) CSTRs in series.
