Solving a Binary Batch Distillation – 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. 362.  Very similar to an earlier problem that we […]

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 […]

Dynamics of a Heated Tank with Proportional/Integral (PI) Control – 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 (Proportional/Integral Contoller) Remember [Accumulation = In – Out + Source/Sink] Think about what you need to do and the answer […]

Dynamics of a Heated Tank with Proportional/Integral (PI) Control – Problem Description

Reference: This is problem 10 from an article  “A Collection of Representative Problems in Chemical Engineering for Solution by Numerical Methods”.  These problems came from Session 12 of the ASEE Chemical Engineering Summer School held in Snowbird, Utah in 1997.  In this problem, you will be modeling the temperature of a tank heated with a […]

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 […]

Reversible, Exothermic, Gas Phase Reaction in a Catalytic Reactor – Problem Description

Reference: This is problem 8.24 in “Problem Solving in Chemical Engineering with Numerical Methods” by Michael Cutlip and Mordecai Shacham, Prentice-Hall ISBN 0-13-862566-2.  In this problem, you will be designing a gas phase catalytic reactor with a pressure drop to accomplish a reversible gas phase reaction. Concepts: Solve a system of ordinary differential equations with […]
