Transcript

  • 1. Polymer/Chemical Reactor Design Muhammad Zafar Iqbal
  • 2. Today <ul><li>Designing of Plug flow reactor </li></ul><ul><li>Example 5.4, 5.5 solve Example: 5.1 from </li></ul><ul><li> chapter 5 Numerical Analysis with C++ </li></ul><ul><li>Space time and Mean Residence time: concept and discussion </li></ul><ul><li>Presentation of Jacketed and Coiled Vessels from Kern. </li></ul><ul><li>Next week: 1- Problems of chapter 5 from Levenspiel (Assigned) </li></ul><ul><li> 2- Networking of reactors </li></ul><ul><li> 3- Finding the best sequence for our purpose </li></ul><ul><li>Required: The students must bring calculators and graph papers along with them. There will be assignments to be solved just sitting in the class. </li></ul>
  • 3. Plug Flow Reactor Plug Flow Reactor : Ideal flow reactor in which no back mixing occurs. The composition of the reaction mixture changes along the length of reactor.
  • 4. Characteristics
  • 5. Basic Design Equation <ul><li>1- </li></ul><ul><li>2- Accumulation = 0 at steady state condition </li></ul><ul><li>3- </li></ul><ul><li>4- </li></ul><ul><li>5- </li></ul><ul><li>6- The equation would be: </li></ul><ul><li>7- </li></ul>
  • 6. For First order Irreversible Reactions
  • 7. Example 5.4
  • 8. Solution <ul><li>1- Calculate expansion factor </li></ul><ul><li>2- </li></ul><ul><li>3- </li></ul>
  • 9. <ul><li>1- Graphical Integration : </li></ul><ul><li>2- Numerical Method : Chapter 5 Numerical analysis with C++ </li></ul><ul><li>Here, as it is a smooth curve, so apply Simpson's rule: </li></ul>
  • 10. <ul><li>Analytical Integration Method: </li></ul><ul><li>Space Time will be : </li></ul>
  • 11. Example 5.5 Solve Yourself
  • 12. Space time and Residence Time <ul><li>Space Time : </li></ul><ul><li>Mean Residence Time: </li></ul>
