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 – Programming Approach

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

Steady-State Material Balances on a Separation Train – Solution

Solve the problem: Execute the script and let’s see what the molar flow rates of D_1, D_2, B_1 and B_2 are?  I’m on the edge of my seat…however, I have been working for a while and kinda need to go, if you know what I mean, but I digress, let’s see it. Molar Flow Rates […]

Steady-State Material Balances on a Separation Train – Programming Approach

Plan your solution: Draw a picture, in this case, list all of your data and equations (see the first post of this series) Remember the fundamentals (steady state material balance) and apply Draw your material or energy balance envelope (continuous distillation at wikipedia) Remember [Accumulation = In – Out + Source/Sink] Think about what you […]

Steady-State Material Balances on a Separation Train – Problem Description

Reference: This is problem 1.5 in "Problem Solving in Chemical Engineering with Numerical Methods" by Michael Cutlip and Mordecai Shacham, Prentice-Hall ISBN 0-13-862566-2.  This problem is about solving the material balance for a set of three distillation columns with a feed containing four components.  Since you’re at steady state with no recycle, you have a […]
