Unsteady Heat Flow in a Slab – Simple Parabolic Partial Differential Equation (PDE)

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 Carnahan, Luther and Wilkes, “Applied Numerical Methods”, Wiley NY 1969 pg 434.  Very similar to an earlier problem that we did […]

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 […]

Fitting Polynomials and Correlation Equations to Vapor Pressure Data – Problem Description

Reference: This is Problem 3 in the ASEE 1997 problem set.   We will be fitting vapor pressure data for benzene to  a polynomial and then to a couple of correlating equations. Concepts: Put the data into arrays so that we can work with it Use Ipython with Scite editor to edit and save files Import […]

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 […]

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 […]

Solving Differential Algebraic Equations – Solution

Solve the problem: So, let’s execute the program we developed in the last post and see how the concentration changes with time and if we believe what the computer is telling us.  If you need a refresher for how to execute a program script in IPython, go to IPython documentation webpage.  It has a tremendous […]
