ChE 423 will provide you with an opportunity to understand one of the core areas of chemical engineering, kinetics and reactor design. The gathering and analysis of appropriate and sufficient data in order to understand the kinetics of a system and design reactors appropriate for it is a key skill found only in chemical engineers. This course should provide you with the fundamental tools needed to approach a wide variety of industrial processes.
Textbook: “Elements of Chemical Reaction Engineering” 4 th Ed., by Fogler, Prentice Hall
Course Goals:
1) Student cognitive skills will improve through interaction with challenging engineering problems in an open, non-threatening environment
2) Students will understand the fundamentals of reaction kinetics and reactor design.
Course Objectives:
1) Write and apply rate laws and material and energy balances to reacting systems.
2) Derive and apply design equations for the three ideal homogeneous reactors: batch, mixed, and tubular flow.
3) Perform preliminary design of an isothermal ideal reactor under various operating conditions.
4) Analyze rate data using integral and differential methods to find rate constants and reaction order.
5) Perform preliminary design calculations for ideal non-isothermal reactors.
6) Understand the seven steps (external mass transfer, adsorption, etc.) of heterogeneous reaction.
7) Derive and evaluate a heterogeneous reaction mechanism, assuming an appropriate rate-limiting step.
8) Obtain effectiveness factors for transport limited heterogeneous reactions.
9) Demonstrate an understanding of multiple steady states, reactor stability, and runaways.
Grading:
There will be regular homework assignments, two exams, and a comprehensive final exam during finals week.
Your final average will be determined by :
Homework 30%
Exams 20%
Final Exam 50%
The grading scale will be (no higher than) 90/80/74/68.
Class Policies
You are HIGHLY encouraged to work together on the assignments in this class. About 1 in 3 of your homework assignments will be group projects. You all bring unique and valuable skills to the process of engineering problem solving. Extensive interaction during the process will do several things for you:
1. it will help you get to know your peers
2. it will make solving the problems easier and less time consuming
3. it will improve your understanding of the material as your peers teach you and you teach your peers
4. it will help you function more successfully in a group environment, a key skill in today's workforce.
Having said this, you DO understand the difference between working together and cheating, so I will not belabor the point.
Your assignments must be legible. You are nearing the end of the process of becoming an engineering professional. Your work must be done well, accurately, and clearly. I would suggest that you take the time to add explanatory text to your homework. This makes it easier for the grader to know what you are doing, but much more importantly, it helps you examine and focus upon your own thought processes. Additionally, you must learn to communicate what you have done to those over you.
Late Assignments will be accepted within reason. If you must miss the deadline, please come by and discuss it with me. Again, this is for the purpose of promoting professional behavior. You will have deadlines in your future jobs. You should meet them, or meet with your supervisor to arrange a change in expectations.
Please feel free to stop by the office as needed. I'm generally available from about 7:30 am on, though I take an early lunch about 11:00 or 11:30. If you prefer, phone or email and arrange an appointment to make sure that I'm around.
