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  […]

Solution of Equilibrium Equations – Programming Approach

Plan your solution: Draw a picture, in this case, list all of your data Remember the fundamentals and apply Draw your material or energy balance envelope (If necessary, list out your equations and problem data) Remember [Accumulation = In – Out + Source/Sink] Think about what you need to do and the answer you want […]

Solution of Equilibrium Equations – Problem Description

Reference: This is from E.M. Rosen and R. N. Adams, “A Review of Spreadsheet Usage in Chemical Engineering Calculations”, Computers and Chemical Engineering, Vol. 11, No. 6, pp. 723-736, but they took it from Henley and Rosen, “Materal and Energy Balance Computations”, Wiley, NY 1969 pg. 376.  I will also be using information from C. […]

Reversible, Exothermic, Gas Phase Reaction in a Catalytic Reactor – Solution

Solve the problem: Okay, let’s open our IPython window, pull up our script and run to see what happens.  We should see the following plot. Where is the plot for x and y?  This only has the temperature.  Hmmm, well, the range for x is only from 0.0 to 1.0 and the temperature in the […]
