A case study employs enhanced Excel and PowerPoint to analyze vapor-liquid equilibrium in chemical engineering, suggesting effective learning methods.
A multicomponent gas–liquid system was considered as a case study project for the course Elementary Principles of Chemical Engineering. In this case study, students were responsible for preparing and using the graphical representation of vapor–liquid equilibrium (Txy diagrams) for a variety of systems and conditions. The solution to this problem is designed as an interactive program utilizing Enhanced Excel, Visual Basic, and PowerPoint. Using a combination of these three software components necessitated the submission of the solution on a computer disk. Submitting only a printout of the same solution may not capture all of the information that is displayed when using generated events from interacting with the various software modules. By using Excel, freshman students can perform a what-if-analysis for which the problem’s solution is sought, with minimum efforts. Furthermore, students will have a decent exposure to the chemical engineering process considered for this case study. Moreover, Excel spreadsheets are useful and easier to modify for parametric studies on the overall process than any other computational tool or program.
