DDB Software Package (DDBSP)

DDB Software Package

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® 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>

Simultaneous Mixture Regression Add-On

These programs are used for the rapid simultaneous regression of any number of binary phase equilibrium and excess property data sets using gE-models.... <more>



Process Synthesis Add-On

The DDBSP Process Synthesis Package contains several powerful tools for process development including prediction of azeotropic points in multicomponent mixtures, construction of residual and boundary curves for ordinary distillation, construction of contour lines and entrainer selection for extractive and azeotropic distillation and extraction....<more>

ARTIST - Property Estimation

The program package ARTIST was developed for the estimation of pure component properties using the most sophisticated methods. It incorporates a large number of different group contribution methods for a multitude of different properties.... <more>

Predictive EOS

The stand-alone package DDBSP-EOS allows a multitude of multicomponent mixture calculations using the Predictive Soave-Redlich-Kwong (PSRK) and volume translated Peng-Robinson (VTPR) equations of state.... <more>

Vapor Phase Adsorption Package

This package contains both the DDB data bank for vapor phase adsorption data (DDB-ADS) as well as suitable software for storage, visualization, correlation, prediction, ... of both single and multi-component adsorption.... <more>



UNIFAC Calculation Software

DDBSP-UNIFAC is a low-cost stand-alone package that allows to estimate activity coefficients, excess enthalpies and excess heat capacities using UNIFAC and mod. UNIFAC for systems with up to 50 components.... <more>
