About DDBST
DDBST GmbH, based in Oldenburg, operates and develops the Dortmund Data Bank (DDB), the world's largest factual data bank for thermophysical properties of pure compounds and mixtures. The company regularly maintains and updates the databases and develops thermodynamic calculation programs, software for property estimation (e.g. Predict Pure, Predict Mix) as well as interfaces to process simulators such as Aspen Plus, PRO/II and UniSim Design. In addition, DDBST offers online services for data bank search and property calculation, training, user support and consulting with a focus on separation processes. Customers include around 50 chemical and engineering companies worldwide as well as universities and research institutions. The DDB is also distributed via a cooperation with DECHEMA as part of the DETHERM data bank; there is a collaboration with the University of Oldenburg on group contribution methods such as UNIFAC, PSRK and VTPR.
