Aspen HYSYS: Chemical Distribution in the Hydrodealkylation of Toluene

Welcome to another post about Aspen HYSYS. This time, I will be working with the synthesis of a process to hydrodealkylate toluene to produce benzene. The statement was inspired by the book Seider, Warren D. (2017). Product and process design principles : synthesis, analysis, and evaluation. New York :Wiley.

Why I am doing this? Because I want my students and students around the globe to feel confident enough to compete in the AIChE Student Design Competition. Also, because former students end up doing process design and keep asking for the videos after leaving my classroom. I also do it for my fellow engineer professors that want to use or adapt this content into their classroom. We are better together!

Used in the following courses: ECH 4644:Process Design (Design 2)

Recorded: Spring 2021/ HYSYS Version: V11

Training Goal (s):

  1. Using HYSYS, simulate the synthesis of a process to hydrodealkylate toluene to produce benzene
  2. Distribute the chemical by focusing on material balances
  3. Learn basic features of Aspen HYSYS including troubleshooting
