Hi everyone,
I am working on the sepration of ethanol from its solution by using a hydrophobic membrane in a pervaporation system.
I have been trying to model and then simulate the pervaporation process in either Aspen Plus with a user defined model or with Aspen custom modeler. I have been trying to see how I can modify the Excel template supplied by Aspen plus for filtration to suit pervaporation but I haven't been successful in any of them.

Has anyone one done a similar pervaporation modeling and simulation with either Excel, Aspen Plus or Aspen Custom modeler or a combination of any.?I would be grateful to receive any example files or notes. My email adress is mydarkoline@yahoo.com
Thank you very much for your attention and assistance

Use balance of mass for this application, in simulator the tool is called "balance"

You should look for this book

"Design and Control of Distillation Systems for Separating Azeotropes"

Thanks. But I am not doing azeotropic distillation. I have an Excel template to modify for my processto link to aspen but it doesn't work.

mydarkonline :
Do not judge the book just by reading its title. Have you checked it? Inside you can find Aspen custom modeler subroutine for pervaporation membrane.

Best regards,

Leon
