WebSep 11, 2014 · This is true only for a Continuous Stirred Tank Reactor (CSTR), not for a Plug Flow Reactor (PFR). CSTR: In an ideal CSTR, the mixing is so intense that there are no concentration variations within the reactor.Each parcel of fluid within the tank has the same number of molecules of the reactant; and, therefore, the stream coming out of the … 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 WebA narrow RTD profile is favored for increasing yield and selectivity. Connecting CSTRs in series narrows the RTD and approaches plug flow reactor (PFR) behavior for a large number of CSTRs. 38 Thus, the RTD profile can be tuned from CSTR to PFR characteristics by choosing the number of CSTRs.
