Steady-state methods separation power

In summary, the mathematical similarity of different steady-state solute zones, critical to the success of seemingly unrelated separation methods, demonstrates the impressive unifying power of the basic transport approach to chemical separations. This unity is emphasized again in the next chapter, where we delve into the classification and comparison of separation methods. 

The example demonstrates that the interaction between reaction and separation systems through recycles can lead to steady state multiplicity and instability even if the stand-alone reactor has a unique stable state. Non-linear analysis is a powerful method to investigate this behaviour.
