Reactor Design for a Single Reaction

We have now developed the basic ideas of continuous chemical reactors, and we have solved these equations for a single reaction in an isothermal reactor. Given r Cj), we solve the equations 

Since we can also write the species balances in terms of a single reactant species A, we actually usually solve the equations 

The solution of one of these two equations is aU there is to this chapter. The subject will become more complicated, but if you can work problems such as these, you should have htde problem as the applications become more interesting. If you can t, you wiU be in trouble. We suggest that you should not simply memorize these two equations but that you should rather be able to derive them or at least feel their meaning. 

Most industrial processes are in fact staged operations where separation units between reactors are used to separate the desired intermediate product from reactants and from other products before feeding it to the next stage, where other reactants are added to form another product. 

The next chapter on multiple reactions in fact uses almost the same equations, but now we have to replace VjF in these equations by so, if you understand these equations,
