2020-8-1 · PFR (plug flow reactor) Simple diagram illustrating plug flow reactor model. In a PFR, sometimes called continuous tubular reactor (CTR), one or more fluid reagents are pumped through a pipe or tube. The chemical reaction proceeds as the reagents travel through the PFR.

plug flow reactor model : definition of plug flow reactor .

The plug flow reactor (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 (see the drawing). The PFR model is used to predict the behaviour of chemical reactors of such design, so that key reactor variables, such as the dimensions of the reactor, can be estimated.

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.

Plug Flow Reactors - Chemical Engineering

Plug Flow Reactors Plug flow, or tubular, reactors consist of a hollow pipe or tube through which reactants flow. Pictured below is a plug flow reactor in the form of a tube wrapped around an acrylic mold which is encased in a tank. Water at a controlled temperature is circulated through the tank to maintain constant reactant temperature.

Chemical reactors - Essential Chemical Industry

2020-8-18 · 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.
