WebThe CSTR-in-series model considers a sequence of completely mixed tanks as a fit to sequential zones of the non-ideal reactor. In a sense, this is similar to considering the PFR as a sequence of non-interacting differential volumes. Thus, both the E and F curves will be the sum of a series: 1 / E (1)!

CSTRs in Series. 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.

WebMay 18, 2024 · A CSTR was used to replace the PFR to ensure the solid transfer during the deprotonation step. Thus 4-CSTRs-in-series was used for deprotonation, methylation, aging, and quench vessel, respectively. A pressure cascade was implemented to transfer the reaction mixture between the 300 mL CSTRs consistently under an inert atmosphere.
