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 now contains approximately 7.4 million data tuples and grows by approximately 8% p. a.
DDBSP, 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.
DDB and DDBST are available with strongly restricted functionality for download in form of a free Explorer Version as well as online via this website.
Basic and Professional Educational Versions are 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.
DDB Software Package (DDBSP)
DDBSP 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 DDBSP into the users working environment. The development of DDBSP 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...
Educatinal Version gives teachers and students many of the possibilities of the full DDB and DDBSP. 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...
Dortmund Data Bank (DDB) Explorer Version
The DDB Explorer Version is a stripped down – but still useful and completely free – basic version of DDB and DDBSP. 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 the availability of data in the full version. more...
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...
Regular external and in-house courses cover both training about applied thermodynamics for process simulation and DDB / DDBSP.
Some of these courses have a long history and are offered by more than 10 or 20 years already.
