Plug Flow Reactor (PFR) The third general type of reactor is the Plug Flow Reactor (PFR). In a plug flow reactor, nutrients (and sometimes organisms) are introduced to the reactor continuously and move through the reactor as a "plug". The system may be either contained (as in a water main, oil pipeline, or blood vessel) or open (as in a .

Tubular reactors resemble batch reactors in providing initially high driving forces, which diminish as the reactions progress down the tubes. Flow in tubular reactors can be laminar, as with viscous fluids in small-diameter tubes, and greatly deviate from ideal plug-flow behavior, or turbulent, as with gases.

Plug flow reactors and perfectly-mixed flow reactors are compared in the former chapter, and the conclusion is that plug-flow reactors are usually advantageous over perfectly-mixed flow reactors for normal reaction kinetics. Reactant concentration changes in these two reactors are also compared based on their design equations to verify this conclusion.

In a tubular reactor, fluids (gases and/or liquids) flow through it at high velocities. As the reactants flow, for example along a heated pipe, they are converted to products (Figure 4). At these high velocities, the products are unable to diffuse back and there is little or no back mixing. The conditions are referred to as plug flow.

A Plug Flow Reactor (PFR) consists in a long, straight pipe in which the reactive fluid transits at steady-state (no accumulation). The main assumptions of this model are that the fluid is completely mixed in any cross-section at any point, but it experiences no axial mixing, i.e. contiguous cross-sections cannot exchange mass with each other.

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. The PFR model is used to predict the behavior of chemical reactors of such design, so that key reactor variables, such as the dimensions of the reactor, can be estimated.
