• Welcome to DDBST GmbH. With the Dortmund Data Bank (DDB), DDBST GmbH provides the worldwide largest factual data bank for thermophysical properties of pure components and their mixtures. A powerful software package for the data handling, correlation, property estimation and process synthesis turns our products into most valuable tools for chemical and process.
• 1 Dortmund Data Bank (DDB) DDB Software Package (DDBSP) Practical Application of Distillation Synthesis for NOx Reduction, Energy Cost Savings, & Improved. Microsoft Office Professional Edition 2003 free download. software here. High accuracy correlations for hundreds of fluids based on data of the Dortmund Data Bank.
• The pure component properties part of the Dortmund Data Bank contains experimental vapor pressure data sets, sublimation pressures, saturation vapor pressures, and vapor pressures above supercooled water. Besides these equilibrium data the DDB also offers a lot of PvT data of water including a lot of data at supercritical conditions.

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.

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. Detailed information can be found on the separate linked pages.

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. DDBSP, the powerful DDB software package features a wide variety of functionalities to optimally employ the vast amount of. DDBSP – Dortmund Data Bank Software Package 2018 1 Introduction This document describes the main program for searching and using experimental data from the Dortmund Data Bank (DDB). The Dortmund Data Bank is actually not a single database but contains over a dozen different data banks for different data types. The data banks are.

DDBST has published an Explorer Version of its software and the Dortmund Data Bank. This DDB Explorer Version is a stripped down – but still useful demo version of the DDB and the DDB software package.

The Explorer Version contains data for 30 components and for the mixtures that can be build from these components. DDBST has decided to publish the experimental data from the Explorer Version directly on the Internet.

Data from eight data banks are available:

* approximate number of data sets compared to the complete data bank.

In total, there are data for 815 systems available. Compared to the systems stored in the Dortmund Dabank this is only a very small fraction.

For most binary systems at least a single diagram with the standard representation of the property is available.
