DDB Access Package: Data Storage, Retrieval, Plotting and Export
- Dortmund Data Bank Software Package - posted in Student: Hello,I am using DDBSP to calculate the dew point and bubble point of a sample mixture. This software allows to choose one of their three methods to calculate: Predictive Soave-Redlich-Kwong, modified Predictive Soave-Redlich-Kwong and Volume-Translated Peng-Robinson equations.
- Dortmund Data Bank. Today the DDB represents the largest computerized data bank for thermodynamic pure component and mixture properties (info and detailed status).Besides data from the open literature, also a large number of data from private communications or company data can be found in the DDB.
Dortmund Data Bank - DDBST GmbH
This essential component of the Dortmund Data Bank 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.
DDB Access Package includes the full set of programs except:

- pure component property regression
- predictive methods
- process synthesis tools
Other parts are included as restricted versions only:
- mixture data simultaneous regression Recval (superlight version with ideal and Margules models)
- pure component property estimation Artist (free version with several simple estimation methods)
It allows to build up in-house literature and experimental property databases as all software tools used at DDBST for input and data test are included. Private data banks can be used from any number of computers as long as these have access to a valid software license. Access to the data can be restricted to individual users and groups.
Major parts of the DDB Access Package are described below:
Dortmund Data Bank
The program Dortmund Data Bank allows to search for experimental data for specific mixtures or literature references. If the Predictive Methods Add-On is available, data can also be loaded from model predictions.
Instead of selecting the components from the DDB, process simulation files (Aspen Plus, ProII) can be selected and the component lists are automatically imported. The database query is entered into the following dialog:
These include:
- storage and retrieval of data to/from data files
- export to 3rd party software like Excel or process simulation software (via IK-CAPE-ppdx, Aspen inp format)
- 2- and 3-dimensional data visualization
- data output in form of tables
- ...
Data Editors for Pure Component and Mixture Data
Convenient data editors are available for pure component and mixture data as well as for supporting basic data. The following dialog shows the data entry program for mixture data:
Literature Data Bank LEAR
The literature data bank software LEAR specifically developed at DDBST. Besides many other features it allows to easily link individual references to multiple files (e.g. pdf, xls, ...). LEAR can handle any number of data bank files. The following figures show a typical query result and the dialog for an individual reference:
Parameter Data Bank ParamDB
A multi purpose parameter data bank (ParamDB) is delivered with the DDB Access Package. ParamDB can hold all kinds of single value or model parameter sets and contains export filters for process simulation software. As with other data bank files, a public and private data bank is used to separately store data sets of DDBST and customers. The following dialog shows a typical data set:

The major product of DDBST is the Dortmund Data Bank (DDB) for thermophysical properties of pure component and mixtures, which was started in 1973 and is continuously updated and extended. DDB grows by approximately 8% p. a.
The powerful DDB software package features a wide variety of functionalities to optimally employ the vast amount of knowledge stored in the DDB and a variety of modern property estimation and regression techniques. Special data mining tools for process synthesis potentially lead to new solutions for engineering and environmental problems.
DDBST offers consulting services ranging from data regression or estimation to the generation of complex property packages or development and up-front evaluation of process alternatives.
A variety of very successful training courses are available covering the thermodynamic and engineering background and to enable customers to efficiently use the data bank and software tools.
DDBST offers a download with strongly restricted functionality in form of a Explorer Version. Data can also be searched online via this website.
Our Educational Version is used at many Universities worldwide to let students become familiar with a wide variety of thermophysical property issues.
Dortmund Data Bank
Today the DDB represents the largest computerized data bank for thermodynamic pure component and mixture properties (info and detailed status). Besides data from the open literature, also a large number of data from private communications or company data can be found in the DDB.
Besides the full data banks, specific subsets are available, e.g. for ionic liquids, pharmaceuticals and intermediates, carbon dioxide containing systems and biofuel related data. more...
DDB Software Package
The integrated software package provides convenient data handling, thermophysical property calculation, regression and estimation as well as a variety of process synthesis tools under a state of the art Windows user interface. Interfaces to other software products like process simulators or MS Excel integrate the DDB into the users working environment. The softwrae development is to a significant part user-driven to ensure customer oriented design and ease of use. more...
Online DDB and Applications
DDBST is currently implementing an Online platform for the DDB as well as physical property calculation and estimation methods. This service includes a free DDB directory and will include pre-paid services for data distribution and estimation in the future. more...
Academic Software
Our Educational Version gives teachers and students many of the possibilities of the full DDB. To achieve this for a small fraction of the price of the commercial version, some of the very complex and advanced features were left out and the experimental data banks are limited to 30 common components and their mixtures. more...
DDB Explorer Version
The DDB Explorer Version is a demo version of DDB. It contains data for 30 components and their mixtures as well as the structure editor ARTIST and several estimation methods for pure component and mixture properties. A full data directory of the DDB is included to search for avaiable data in the full version. more...
Consulting
Besides delivering data bases and program packages, DDBST GmbH is engaged in consulting and special projects for various customers. These projects range from simple data estimation to setting up and verifying complex parameter sets for process simulation. more...
Education
Regular external and in-house courses cover both training about applied thermodynamics for process simulation and DDB.
Some of these courses have a long history and are offered by more than 10 or 20 years already.
