Chapter 11: Nonisothermal Reactor Design: The Steady State Energy Balance and Adiabatic PFR Applications

Plot of XEB and XMB versus T

    For Part C
Second Order Reaction Carried Out Adiabatically in a CSTR
 
   

Our plot of X EB and X MB shows that we will have three possible operating points at:

X = 0.062 at T = 286 K (stable)
X = 0.38 at T = 318 K (unstable)
X = 0.75 at T = 355 K (stable)  

It looks like the higher conversion, stable operating point (X = 0.75 at T = 355 K) will be our desired steady state.  

Our corresponding Polymath program looks like this:

NOTE: Our use of d(T)/d(t)=2 in the above program is merely a way for us to generate a range of temperatures as we plot conversion as a function of temperature.
