Reactor Design 7 Reactor Design 7 Presentation Transcript

  • Polymer/Chemical Reactor Design Muhammad Zafar Iqbal
  • Today
    • Plug flow reactors in series and in parallel
    • CSTR single Vs CSTR in series
    • PFR Vs CSTR
    • How to tackle with practical problems in dealing with CSTR
    • You have the reactors but unknown conversions
    • You know the conversion and need to design the system following that conversion needs.
    • Next Lecture: Recycle Reactors + Autocatalytic Reactors
    • Brief discussion and concepts
  • Solve Yourself
  • CSTR if single and if in series???
    • For two CSTR in series, 40 % conversion is achieved in first reactor. What is the total volume of the two reactors necessary for 80% overall conversion of a species entering reactor “1”? (F A0 = 0.867 mol/sec), F An = F A0 (1- X An )
    • Data:
    • X -r A (mol/lit.sec.)
    • 0.0 0.0053
    • 0.1 0.0052
    • 0.3 0.0050
    • 0.4 0.0045
    • 0.5 0.0040
    • 0.6 0.0033
    • 0.7 0.0018
    • 0.8 0.00125
    • 0.85 0.00100
    Requirements: a- Single CSTR X= 80% b- Single PFR X= 80% c- Two CSTRs equal sized d- Two PFRs equal sized e- 8 CSTRs equal sized f- 8 PFRs equal sized g- PFR + CSTR H- CSTR + PFR i- CSTR + PFR + CSTR J- PFR+ CSTR + PFR
