The plug flow reactor model (PFR, sometimes called continuous tubular reactor, CTR, or piston flow reactors) is a model used to describe chemical reactions in continuous, flowing systems of cylindrical geometry.
Learn what a plug flow reactor is, how it works, and how to derive its equation. Find out the characteristics and applications of this type of reactor in chemical engineering.
A plug flow reactor is a cylindrical shaped tank where chemical reactions occur between a catalyst coated in the sides of the wall of the reactor and an inlet reactant ( Fig. 10.2A ). Plug flow reactors are mostly used for their unique property of not requiring any mixing.
Sep 24, 2022 · 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.
Learn what plug flow means in flow reactors and how it affects reaction time, yield and purity. Find out the advantages of plug flow chemistry and see a schematic diagram of a plug flow reactor.
