The GPA Data Bank, 5th Edition was jointly development by DDBST GmbH and EPCON International (developer of the popular API Technical Data Book and Engineer’s Aide software). The product delivers over 35 years of GPA research data for immediate, productive use in process simulation tools. Included is a completely remastered thermophysical property database with all 220 research reports and technical publications and powerful data fitting, correlation, estimation, and phase equilibrium software applications.

New data for low-boiling hydrocarbons are included that where never before available in previous versions of the GPA Data Bank published by Penn State (1st Ed.-1983, 2nd Ed.-1990, 3rd Ed-1993) and Oklahoma State University (4th Ed.-2000). The result is software that can be widely used by engineers within your organization with direct links to major process simulators to immediately improve your company’s gas processing operations.

Pure Component and Mixture Properties

The GPA Data Bank with the stored pure component properties and the comprehensive GPA VLE, LLE, and VLLE mixture data is the ideal tool for fitting reliable model parameters or testing available parameters before process simulation. Data are available through the convenient DDBST data bank software, which provides extensive functionality for data visualization, export and regression.


Thermophysical Property Estimation

A light version of the ARTIST software provides estimation of pure component properties using the molecular structure and several important and well known estimation methods for a multitude of different properties. Using a special coding scheme for molecular structures, ARTIST is able to take into account the chemical neighborhood of the individual groups thus implementing chemical know-how. To ensure the correctness of the algorithm, the program has already been tested for years during the development of the well known UNIFAC and mod. UNIFAC methods. ARTIST utilizes a user-friendly Windows graphical user interface. Results can be copied to the clipboard or automatically sent to Microsoft Excel™ for further processing.


GPA Data Bank Explorer

The GPA Data Bank Explorer provides electronic access and searching capabilities for all 191 GPA Research Reports and 29 GPA Technical Publications. The 10 software programs are loaded from a convenient Outlook style navigation pane with two categories of software to choose from. The GPA Data Bank Explorer provides 37 years of GPA research in a convenient, intuitive software interface developed over 10 years in the API Technical Data Book software product.


Rigorous 3-Phase Flash

Utilize the advanced 3-phase flash engine provided in the GPA Data Bank to accurately determine the 3rd liquid phase vital for compressor operations and pipeline transportation applications. Developed over a 10 year period by the API Technical Data Committee - the 3-phase flash outperforms major simulators in 5 key areas for hydrocarbon system design and operations.
