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. Assessment of mixing properties WebMay 29, 2024 · 5.2 Plug Flow Reactor. PFR is an idealized flow reactor such that along the direction of the flow all the reaction mixture are moving along at the same speed; there is no mixing or back flow. The contents in the PFR flow like plugs, from inlet to outlet. What is a ideal reactor? Ideal reactors are model systems for which the transport and mixing …

In PFRs, however, the reactor contents are not continuously stirred. Instead, chemical species are flowed along a tube as a plug, as shown in Figure 25.2. As the plug of fluid flows through the PFR, reactants are converted into products. green flag accord housing
