Multiple Reactions in PBR Part 2

Organized by textbook: learncheme.com/
A continuation of part 1, this screencast focuses on using Polymath to solve the differential equations set up in part 1 and inspect the influences of certain operating conditions on reactor performance. Made by faculty at the University of Colorado Boulder, Department of Chemical and Biological Engineering.

Glad you like them. Please share with others!

Excellent series of videos! However, I have one question. If you were given partial pressures instead of concentration in the rate equations, would you use the ideal gas law and solve for n/v? And then follow the rest of your steps. Thanks!

[@LearnChemE]

Alex Crocker Yes, you could convert partial pressures to concentrations and continue through the rest of the steps. Thanks for asking!

[@alexcrocker7111]

I ended up realizing that the rate constant had units of bar in it, so it worked itself out. Thanks for the response!

@@LearnChemE If the conversion is known say 70%, how to write the equations?

Great Video!
How do i account for vo for a liquid phase reaction?

[@alankullmann2190]

Great!
one question: What can i do in case of drop pressure?

[@LearnChemE]

Good question! We actually have another screencast describing how to solve a packed bed reactor with pressure drop: ruclips.net/video/toGV2wDJSag/видео.html

Thank you very much!!
I'd like to know where did you get the rate law's?

[@EduardoHernandez-cy4zl]

is there any book or reference where I can find the rate expressions for such a system??

[@pavethrasivanesan9232]

How did you get the 0.000001 for the Selectivity coding?

[@xOxAdnanxOx]

It just to make polymath work because otherwise it will give you error ( you can divide by zero ) so you just but that value which almost a zero and won't affect final calculations
