Steps to Enable the MSE-SRK Framework in Aspen HYSYS
4.1. Database Naming Convention
4.2. Loading the Database
4.3. Confirmation in the Trace Window - Conclusion
Overview
The OLI MSE-SRK thermodynamic framework was developed for systems with high pressure (over 80 bar) and gasses containing high concentrations of carbon dioxide and hydrocarbons from C1 to C7. A good article can be found here: Mixed Solvent Electrolyte-Soave-Redlich-Kwong (MSE-SRK)
The MSE-SRK option in all of the OLI software products, including OLI Engine in Aspen HYSYS, is enabled in the MSE thermodynamic framework by adding a user database. There is no specific switch to be used.
Disclaimer
This tutorial uses the OLI Engine version 12.0 in Aspen HYSYS. While the tutorial is applicable to other versions, there may be some small differences in the user interface and results. This tutorial also uses Aspen HYSYS V14.5 with the same disclaimer.
Assumptions for Using This Tutorial
This tutorial assumes:
- Proficiency in Aspen HYSYS: Users are expected to know the basics of Aspen HYSYS software and its interface.
- Knowledge of OLI Databank Integration: Users should understand how to enable a custom OLI databank in Aspen HYSYS when using the OLI Electrolyte Fluid Package. If not, please refer to Using a Custom OLI Databank in Aspen HYSYS.
Additionally, this tutorial is based on OLI Engine version 12.0 and Aspen HYSYS V14.5, though it can be applied to other versions with minor differences in the user interface and outputs.
Steps to Enable the MSE-SRK Framework in Aspen HYSYS
4.1 Database Naming Convention
A unique characteristic of OLI databases is that the first three characters of the database name must be unique. This means users cannot name the database MSESRK, as the master MSE public database is named MSEPUB.
Instead, the required database for enabling the MSE-SRK framework is named SRKMSE.ddb. This database is stored in the following system directory:C:\ProgramData\OLI Systems\Databanks\12.0.0
(Note: The version number in the directory path may vary depending on your OLI installation.)
4.2 Loading the Database
To enable the OLI MSE-SRK framework in Aspen HYSYS:
- Start Aspen HYSYS and add the OLI Fluid Package as you would in the usual process.
- Ensure that the MSE thermodynamic framework is selected and add the database by clicking Additional Database.
- Add the path from above for the system database:
- Enter the name of the database as
SRKMSE
and select the checkbox to activate it. - Close the database configuration dialog box.
4.3 Confirmation in the Trace Window
If this is the first time you are loading the database in Aspen HYSYS V14.5, a message will appear in the trace window to confirm the activation of the database.
Once this step is complete, the MSE-SRK framework will be fully enabled for use.
Conclusion
The OLI MSE-SRK Thermodynamic Framework provides a powerful tool for modeling high-pressure, hydrocarbon-rich systems. By integrating this framework within Aspen HYSYS, users can leverage its capabilities for advanced simulations in challenging operational environments.
With the outlined steps, users can confidently enable and configure the framework, ensuring their models benefit from the sophisticated thermodynamic predictions that OLI Systems is renowned for.
