Automation of Heating Curve and Thermodynamic Property Extraction from Aspen HYSYS to MS Excel Using VBA Integration
Project Description
In process simulation and heat exchanger analysis, extracting detailed performance data such as heating and cooling curves is essential for design validation and optimization. Manually collecting thisdata from simulation tools can be time-consuming and inefficient. This project focuses on automating the extraction of heating curves and other thermodynamic properties from Aspen HYSYSinto Microsoft Excel using VBA programming.
The methodology involves integrating Aspen HYSYS with Excel through VBA macros that communicate with the simulation environment. By selecting a heat exchanger and specifying the tube or shell side, users can automatically retrieve heating curve data and related properties. The system relies on weighted design methods in HYSYS to ensure accurate curve generation with adjustable data points.
Additionally, the project allows customization by adding new property calculations using moniker names available in HYSYS installation files. This flexibility enables engineers to extend the tool for advanced analysis. The integration significantly improves data accessibility, reduces manual effort, and enhances workflow efficiency in thermal system analysis.

Optimization Strategy
To successfully extract heating curves, theHYSYS simulation must first be properly configured with a single active case running. The heat exchanger should use the weighted design method to ensure accurate curve generation. Once configured, Excel VBA macros establish a connection with the active HYSYS session to access simulation data.
Furthermore, users must ensure correct selection of heat exchanger units and curves through the Excel interface. The process involves sequential execution of macro commands to retrieve available exchangers, select curves, and extract data. Proper validation of results ensures that the transferred data accurately represents the simulation output.
HYSYS–Excel Integration Setup
This strategy involves establishing a connection between Excel and HYSYS using VBA. The simulation must be active, and only one case should be open to ensure proper communication between systems.
Curve Selection and Data Extraction
Users select the desired heat exchanger and curve type (heating or cooling) from Excel dropdown menus. The macro then retrieves and populates curve data into structured spreadsheet tables.
Custom Property Expansion
Additional properties can be included by modifying VBA code and using moniker names from HYSYS RDF files. This allows advanced customization for specialized engineering analysis.
