WebGeneral Information. Continuous stirred-tank reactors (CSTRs) are open systems, where the material is free to enter or exit the system, that operate on a steady-state basis, where the conditions in the reactor don’t change … 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)! N Nt N NNt e N
