A New Set of Problems to Work…From the Early Days of Personal Computers

What Next? We just completed working the ten problems from the 1997 ASEE workshop.  We worked a variety of problems that had solutions with other software packages such as Microsoft Excel, MATLAB, Mathematica, Maple and Polymath.  Please compare and let me know what you think.  Now, let’s look at the following journal article for a […]

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 […]
