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

WebComparison of the volumetric flow rates in a CSTR (Equation 6.38) and a CPFR (Equation 6.39) shows that, for the same conversion, the flow rate in the CSTR will be lower than that in the CPFR.
