The GPA Data Bank, 5th Edition 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, and phase equilibrium software applications.

new VLE data for low-boiling hydrocarbons 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 GPA Data Bank, 5th Edition was jointly development by EPCON International (developer of the popular API Technical Data Book and Engineer’s Aide software) and DDBST (developer of the popular Dortmund Data Bank and co-founder of the UNIFAC consortium). 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.

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.

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. Fit GPA data to gE-models or equations of state, for the development of group contribution methods and for fitting the required interaction parameters for process simulation.

It is especially helpful for the critical examination of model parameters prior to process simulation. For the development of reliable group contribution methods with a broad range of applicability nearly all available information covering a large temperature and the whole concentration range for a variety of compounds very different in size can be used.

Thermophysical Property Estimation

The ARTIST software provides estimation of pure component properties using the molecular structure. It incorporates a large number of different group contribution 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.

Maximizing your GPA Research Investment

The GPA Data Bank maximizes the benefits of your GPA research investment by directly applying GPA data to the simulation and design of your gas processing operations.
