In this demonstration, the liquid-phase reaction A + 2B C takes place in an isothermal plug flow reactor. Only A and B enter the reactor, and the user inputs the mole fraction of A in the feed. The reaction is first order in the concentration of A, but the user inputs the reaction order with respect to B and the value of the rate constant.

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.
