Solving a Binary Batch Distillation – Solution

Solve the Problem:

Let’s run the program and see what the plot looks like:

henleySeader362FinalPlot

Well, not much more to say.  From the plot, x_w(t = 5 hours) is about 0.35.  Henley and Seader calculated xw (t = 5 hours) = 0.351.  I’d say pretty close.  It’s easy to calculate W(t).   It is 100 kg – 10 kg/hr*5 hr = 50 kg.  So, this one is pretty easy.  I’m not sure what to do next, I’ll think about it.  Any suggestions?
