Most reactors used in industry approximate the ideal batch reactor, PFR, or CSTR. In fact, real reactors can be modeled as networks or combinations of multiple plug-flow and stirred-tank reactors (Towler and Sinnott, 2013).

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.
Reactor Insights. Based on reactor, the market is segmented into continuous stirred tank reactors, Microreactors, plug flow reactor, and microwave system. Continuous stirred tank reactors held the leading market share of 40.99% in 2018.

The aim of this study is to simulate the flow by computational fluid dynamics (CFD) and provide information on flows inside the system to aid the design of an ideal reactor. The major influential parameters of the flow inside the reactor can be designated such as porosity, height, width, number of filters, and distances between the baffles.

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.
Plug Flow: In addition to excellent radial mixing, continuous reactors require plug flow conditions. Plug flow conditions means that all the material processed through the reactor must have the same residence time so that the chemicals exiting the reactor have witnessed the same reaction conditions of reactive species contact-time aging-temperature history.

Under flow conditions, each portion of the reactor is defined by specific concentrations of the starting material(s) and product(s): in this sense, the reaction profile within a flow reactor can be defined within space rather than time.
Feb 16, 2019 · Mixed flow reactor (CSTR) • ideal steady-state flow reactor is called the mixed reactor, the backmix reactor, the ideal stirred tank reactor., it is a reactor in which the contents are well stirred and uniform throughout. Thus, the exit stream from this reactor has the same composition as the fluid within the reactor
