DDB Software Package (DDBSP)

Since the start of the DDB in 1973, a large number of software tools have been developed to search, retrieve, export, visualize and regress the data. Later these programs were extended to cover further applications like e.g. process synthesis. At the same time, data and parameter communication with other software products was enhanced. Today it is even possible to use the thermodynamic calculation engines of Aspen Plus®, UniSim Design® , Simulis Thermodynamics® or Pro/II® from inside the DDB Software Package DDBSP.

All programs have been integrated under the MS-Windows graphical user interface and can be easily used even without studying the manuals.

The following table compiles most of the major parts of DDBSP. Detailed information can be found on the separate linked pages.

DDBSP Basic Package

This essential component of the Dortmund Data Bank Software Package (DDBSP) provides data storage, data input editors, retrieval, graphical representation, import/export for all data banks including complete data directory and demo versions of all non-licensed data banks.... <more>

Pure Property Regression Add-On

The regression add-on for pure component properties allows for extended parameter fitting, calculation and graphical representation options for various correlation equations for the different pure component properties that allow customization of simulation software for a better description of your specific mixtures.... <more>

Mixture Regression Add-On

The regression add-on for mixture properties allows extended parameter fitting, calculation and graphical representation options for VLE, HPV, hE, LLE and AZD ( gE models, equations of state, electrolyte models).... <more>

Mixture Prediction Add-On

The predictive methods UNIFAC, mod. UNIFAC, ASOG, PSRK, COSMO-SAC, COSMO-RS(Ol)  as well as calculation via Aspen Plus® and ProII are provided to estimate data and binary parameters. (includes s-profiles for 25 components and GC2GE).... <more>

Prediction Parameters Add-On

In order to provide reliable model parameters for the calculation of pure component and mixture properties, DDBST is for some time engaged in regression of the different data from the DDB. Currently numerous parameter sets are available.... <more>
