PFR with Continuous Uniform Feed of Reactant along the Whole Reactor

7 PFR with Continuous Uniform Feed of Reactant Along the Whole Reactor 

Consider a product C being produced in a PFR by a second-order reaction  

However, an undesired product A2 is also formed by the second-order dimerisation reaction  

In the following paragraph we are going to formulate the mole balance equations for A and B. In this reactor arrangement we have two feeds direct feed into the reactor inlet of a solution of B with volumetric flow rate I d and concentration CBo. and sidewise feed of a solution of A with concentration CA0 and a uniform rate of feed of /a, 

The mole balance for A applied to a differential slice of the reactor is as follows. Remember that there are two inlet terms for A, one term expressing A carried forward with the main flow inside the reactor and a second term through the wall 7X4 CAo-
