Solution of Equilibrium Equations – Solution

Solve the Problem: Let’s see what the output of the program looks like: As a check, I added up the mole fractions to ensure they add up to 1.0.  If they didn’t, something is wrong.  Let’s compare to the what Rosen and Adams calculated. CH4 R&A = 0.226  EWP = 0.226 H2O R&A = 0.110  […]

Calculate a Four Component ‘Flash’ – Solution

Solve the Problem: Let’s see what the output of the program looks like: We can see that the mole fractions are propane = 0.071, butane = 0.183, pentane = 0.310 and hexane = 0.435 and they (whew!) add up to 1.0 which is a good sign.  We calculate α = 0.1219 and Rosen and Adams […]

‘Graphical’ Evaluation to Calculate the Number of Transfer Units – Solution

Solve the Problem: Calculate the number of transfer units (Nog) Run the program and let’s see what the output shows.  It will show up in your IPython window. The answer we get is NOG = 3.52 transfer units.  Henley and Seader got 3.44 transfer units (obtained graphically) and Rosen and Adams calculated 3.73 units (with […]
