Plug Flow Reactors (PFRs) Another type of reactor used in industrial processes is the plug flow reactor (PFR). Like the CSTRs, a constant flow of reactants and products and exit the reactor. 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.

The PFR model is used to predict the behaviour of chemical reactors of tubular design, so that key reactor variables, such as the dimensions of the reactor, can be estimated. Fluid going through a plug flow reactor is modeled as flowing through the reactor as a series of infinitely thin coherent "plugs", each having a uniform composition.
