Reactive Distillation Modeling

[John Hedengren]

David,

There are a couple examples that can help you as you develop your application.

(1) One is the pendulum example:

http://apmonitor.com/wiki/index.php/Apps/PendulumMotion

This is a simulation of an index-3 DAE.  All of the Index-0 to Index-3 forms of the model are shown in the description.  The point of this exercise is to demonstrate that any index DAE can be solved with APM.

(2) I've attached a distillation column example that can be run with either Python or Matlab.  You'll need to change the archive from distillation_zip to distillation.zip before you extract the files.  This may be a good template for you as you seek to develop your model.  Here is some additional information as well on distillation column models:

(3) There is relatively little documentation on the built in objects.  I suspect that you'll want to develop your own equations anyhow.

Please let me or others in the user's group know if you need help getting started.

Best regards,

Hello,

 

Thank you for the software registration.

I have some reactive flash models, and am interested in investigating the stability of stationary points of the index-2 DAE. I read somewhere that APMonitor could handle index-2 and 3 systems (which Matlab cannot). If successful, I would like to try modelling some reactive distillation columns. Is there any additional documentation on APMonitor objects?

 

Thank you,

Daithi
