Polymer/Chemical Reactor Design
Muhammad Zafar Iqbal
Today• Designing of Plug flow reactor• Example 5.4, 5.5 solve Example: 5.1 from
chapter 5 Numerical Analysis with C++• Space time and Mean Residence time: concept and discussion• Presentation of Jacketed and Coiled Vessels from Kern.
Next week: 1- Problems of chapter 5 from Levenspiel (Assigned) 2- Networking of reactors 3- Finding the best sequence for our purpose
Required: The students must bring calculators and graph papers along with them. There will be assignments to be solved just sitting in the class.
Plug Flow ReactorPlug Flow Reactor: Ideal flow reactor in which no back mixing occurs.The composition of the reaction mixture changes along the length of reactor.
Characteristics
Basic Design Equation1-
2- Accumulation = 0 at steady state condition
3-4- 5-
6- The equation would be:7-
For First order Irreversible Reactions
Example 5.4
Solution1- Calculate expansion factor

1- Graphical Integration:
2- Numerical Method: Chapter 5 Numerical analysis with C++Here, as it is a smooth curve, so apply Simpson's rule:
Analytical Integration Method:
Space Time will be:
Example 5.5
