The participation in the project is available on easy terms. We decided to organize the membership in periods of five years (extension possible) which implies annual payment of the consortium fee. The graduation can be taken from the following table:
|Member classification||Yearly contribution
(including influence on further developments)
|Large chemical companies as well as large petrochemical companies (amongst the top 50)||Euro 9,000|
|Middle-ranged chemical companies and engineering companies||Euro 6,000|
|Small chemical companies||Euro 3,000|
|Research group of a university||Euro 1,500|
|+ 2.5% yearly increase
(roughly according to the inflation rate)
Please note that the revised and extended parameter tables obtained within the consortium are not available via the different process simulators (Aspen Plus®, CHEMCADTM, PRO/II, HYSIM,...) or via the software package from DDBST GmbH. They will be supplied exclusively to the contributing companies together with an implementation guide to current process simulators.
It is allowed to use the new group interaction parameters and experimental data measured within the project only in the member company (including affiliated companies). It is not allowed to pass on the information to third parties.
The next joint DDBST user and UNIFAC consortium member meeting is scheduled for September 22th to 23th, 2020.
