Hello everyone! I would like to ask you how can I insert the vapor pressure data of a component in aspen plus?

I would search on AspenTech Support website.  Also, if you Google "how can I insert the vapor pressure data of a component in aspen plus?" you get many answers.  One is a YouTube that sounds like it shows exactly what you seek, https://www.youtube....h?v=aHGDrHWu0sA

Hi Latexman,
Thank you for your reply.
I was not asking how to generate the curve in aspen. But, how I can insert the vapor pressure data of a component that does not exist in databank of Aspen Plus.

Yes, that did not match exactly, did it.

 

In my Aspen+ V12.1, I use the "User Defined" Component Wizard on the Components - Specification / Selection tab to create a new component.  You need to enter molecular weight, normal boiling point, molecular structure, vapor pressure and ideal gas heat capacity data to utilize the Aspen property estimation system.  You have to name your vapor pressure data set and then you get a table to enter your temperature vs. vapor pressure data.

 

This was covered in the "EAP201: Aspen Plus: Physical Properties for Process Engineers" course I took many years ago.
