A member of the UNIFAC company consortium will receive in annually intervals

• access to the results of about 40 membership fees p.a. (increasing tendency) for only one membership fee p.a., including:
• already existing but not yet published Modified UNIFAC (Dortmund) parameter sets (including all previous deliveries), all shown in the current parameter matrices, Fig. 1 and Fig.2 (written and on CD-ROM)
• already existing but not yet published original UNIFAC parameter sets (including all previous deliveries), all shown in the current parameter matrix, Fig. 3 (written and on CD-ROM)
• already existing but not yet published PSRK parameter, shown in the current parameter matrix, Fig. 4 (written and on CD-ROM)
• the modified Aspen Plus TBS customization files in order to include the latest Modified UNIFAC (Dortmund), original UNIFAC, and PSRK version into the Aspen Plus simulation engine as well as Aspen Plus user interface
• an implementation guide to the Aspen Plus simulator (written + on CD-ROM)
• an Aspen Plus User Databank that contains the structural information of all components from the Aspen Plus System Databank which could not be described with the latest group assignment of UNIFAC, mod. UNIFAC (Do), and PSRK
• customization files and instructions for Chemcad implementation including the latest UNIFAC, Modified UNIFAC and PSRK delivery
• all the experimental data measured within this project (VLE, h^E, SLE,..., written + on CD-ROM)
• current versions of additional software tools, which enable the chemical engineer to estimate the prediction quality of the model Modified UNIFAC (Dortmund) when it is applied to a specific separation problem (on CD-ROM)

In sponsor meetings, which are held every year in September (in Oldenburg) the sponsors of the first category (see below: membership conditions) even have the possibility to influence the direction of further developments.

This yearly delivery (distributed at the sponsor meetings or sent to our members each year in September / October) can be made use of within the company at least 2.5 years prior to publication of selected parameters in a scientific journal. Notice that even after the 2.5 year period only a few of the new and revised parameters will be published and the parameters will not be available from DDBST GmbH as part of the program package DDBSP for non-sponsors of this consortium.

Additionally, the sponsors can get profit of various measurements of thermodynamic data performed in our research group and in the Laboratory for Thermophysical Properties (LTP GmbH). The price list for thermodynamic measurements is available on request.
