Aspen Plus has its own distillation model. You need to use RadFrac distillation column in Aspen-Plus, in order to optimize your distillation process and then compare the results with the results of Matlab.

Thank you everyone for your fruitful responses. If there is any workshop or video lectures available for the above stated problem then please enlighten me.

Dear Sidharth

Please follow the link, https://www.mathworks.com/help/mpc/examples/design-and-cosimulate-control-of-high-fidelity-distillation-tower-with-aspen-plus-dynamics.html

You can get the AM Simulation Block in Matlab Directory....

Thanks

it depends on your variables. for example, number of trays can not altered by external program and you may use discrete optimization, or at least use optimization tools like particle swarm or response surface ....

Its possible to manipulate all the variables (including number of trays) of Aspen Plus simulations through a connection with Matlab.

If you want, send me ( [email protected] ) the simulation and I try to make several optimizations.

Hi Sidharth

You can see the following papers, might be of some help for you.

Article Process Synthesis and Optimization of Propylene/Propane Sepa...

Article Rigorous Design of Complex Distillation Columns Using Proces...

You will need some standard files to set up the connection between MATLAB and HYSYS.

did you try Amsimulink??

Create a dynamic simulation and then use the block Amsimulink into Simulink. Now, you have optimization block in Simulink,

this will help you.

note: Amsimulink only works in MATLAB's 32 bit version

I decided to put the requested example in matlab central. See the following link:

la.mathworks.com/matlabcentral/fileexchange/69464-aspen-plus-matlab-link

you can use "dos" on matlab

I use "dos" for Switch two programs (MATLAN and ANSYS)

I write :

>> dos ' " c:\ program Files\ANSYS Inc\v150\ansys\bin\winx64\ANSYS150.exe" -b -i foransys.text -o outpute.out';

1- first part is address of secend program ( ANSYS )

" c:\ program Files\ANSYS Inc\v150\ansys\bin\winx64\ANSYS150.exe"

2- Second part is set to the settings

-b

3- Third part is symbol of input and after that you should write name of input

-i foransys.text

4- Fourth part is symbol of output and after that you should write name of output

-o outpute.out';

Aspen plus and MATLAB can directly connect to each other and make a good interface by ActiveX method.

aspen=actxserver('Apwn.Document.36.0');

Thank you so much for all of the files that posted in this responds. Very useful

Andres Felipe Abril Duran Thank you for your answer here and your example in matlab central. I got a lot from that. And could you please send your simulation file mentioned in matlab central to me ([email protected]) because I couldn't visit the website you provied. I appreciate it.

Wu Zq Simulation File has been sent.

Best regards,

Andres Felipe Abril Duran I've received it and thank you very much.

thanks for sharing

Hi, Can someone guide me about how to establish a link between Aspen EDR and Matlab for optimization purpose?

Thanks and Regards

Looking Forward

I am using this code, but after inserting the last line Matlab is showing error

"Error using Interface.HYSYS_10_Type_Library_SimulationCases/Open

Invoke Error, Dispatch Exception: Access is denied."

How to solve this issue?

myobject = feval('actxserver','Hysys.Application');

myobject

get(myobject)

invoke(myobject)

FileNamePath = 'Hysys_Matlab2';

MySimCase = myobject.SimulationCases.Open([cd,strcat('\',...

FileNamePath,'.hsc')])

If anyone can suggest me how to get rid of this problem ?

Unlike MathLab, Aspen used to have no built-in minimization routines, but now it does.

Sorry for a late reply.

If you are willing to switch over into the tropical lands of Python I have a library which you can use:

https://github.com/YouMayCallMeJesus/AspenPlus-Python-Interface There is also some tutorials, documentation, cases and such.

You are able to edit the flowsheet, run, set values, get values, debug, automatically extract all outputs and insert all inputs into blocks and much more.
