Create a Fluid Type from a PPDX file

You can import a PPDX (.ikc) file to create a Fluid Type in a Model Library. When you create a Fluid Type in this manner, AVEVA Process Simulation creates the following files in the %userprofile%\My Thermo Data folder, where <ikcFilename> is the name of the .ikc file:

• <ikcFilename>.lb1 and <ikcFilename>.lb2

  A custom thermodynamic library with data banks from the .ikc file. If this thermodynamic library already exists, you can choose to overwrite the data in the thermodynamic library with the data from the .ikc file.

• <ikcFilename>.bnk

  A list of the data banks that AVEVA Process Simulation imported from the .ikc file. AVEVA Process Simulation imports data banks for each type of supported data in the .ikc file. For example, if the .ikc file contains NRTL binary interaction data, AVEVA Process Simulation creates an NRTL data bank in the custom thermodynamic library and imports the data from the .ikc file into that data bank.

  All of the data banks are named BASE, regardless of the data bank type. This allows you to easily add these data banks to a Fluid Type because the name of the data bank will always be <ikcFilename>:BASE.

• <ikcFilename>.rpt

  A detailed report of the data that AVEVA Process Simulation imported from the .ikc file.

• <ikcFilename>.BASE.cmp

  The list of components in the PURECOMP data bank for the custom thermodynamic library. The components in the thermodynamic library match the components from the .ikc file.

  Note: The custom thermodynamic library from the .ikc file does not automatically appear in the list of thermodynamic libraries in the TDM UI. If you want to view or change this thermodynamic library in TDM, you must first open it in the TDM UI. AVEVA Process Simulation can still access the data from this thermodynamic library even when it does not appear in the list of thermodynamic libraries in TDM.

The newly created Fluid Type has the same name as the .ikc file. The Fluid Type is always a Compositional Fluid Type that contains all the components from the .ikc file. By default, the initial composition values are 1 for the first component and 0 for all other components in the Fluid Type. You can immediately use the Fluid Type in your simulation without changing its configuration, but you may want to modify the initial composition values to better suit your simulation needs.

The Fluid Type has the following configuration in the Fluid Editor:

If the .ikc file includes binary interaction data for any of the following thermodynamic methods, AVEVA Process Simulation sets the System selection to the first thermodynamic method for which binary interaction parameters are present and adds the <ikcFilename>:BASE data bank to the Binary Interaction Banks list.

• Non-Random Two-Liquid (NRTL)

• Wilson

• Universal Quasi-Chemical (UNIQUAC)

• Soave-Redlich-Kwong (SRK)

• Peng-Robinson (PR)

If the .ikc file does not include binary interaction data, AVEVA Process Simulation sets the System selection to Soave-Redlich-Kwong (SRK) and the Binary Interaction Banks list includes only the default data bank (System:SIMSCI).

If the .ikc file includes data for Henry's law constants, AVEVA Process Simulation selects the Use Henry's Law checkbox, adds the <ikcFilename>:BASE data bank to the Henry's Law Data Bank list, and selects the H Solute checkbox for all corresponding components in the Fluid Type. Otherwise, the Use Henry's Law checkbox is cleared and the Henry's Law Data Bank list is unavailable.

Create a Fluid Type from a PPDX file

1. Right-click a blank space in the Model Library pane, and then select Create New Fluid From PPDX.

   The Open dialog appears.

2. Browse to and select the PPDX (.ikc) file that you want to import.

3. Select Open.

   AVEVA Process Simulation creates a new Fluid Type with the same name as the .ikc file.

4. Open the Fluid Type in the Fluid Editor and change the initial compositions of the components, if desired.
