Plug flow reactor diagram. The fast reaction technique in plug flow systems is based on a continuous flow fast kinetic system. Here is a diagram of a plug-flow reactor.
Details
Introduction. A plug flow reactor (PFR) is a tubular reactor used in chemical reactions. Reactants enter one end of the PFR, while products exit from the other end of the tube. A PFR is useful because of high volumetric conversion and good heat transfer.
