Modified UNIFAC(Dortmund): Progress 1997 to 2014A member of the UNIFAC company consortium will receive in annual intervals access to the results sponsored by all membership fees for just one membership fee p.a. This includes

  • 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
  • The Implementation of PSRK, Original UNIFAC and Modified UNIFAC parameter updates from Invensys Process Systems. This implementation is available as system libraries for Dynsim 4.5, ROMeo and PRO/II 9.0 users (on CD-ROM).
  • an UNIFAC Model Editor, in order to view and edit the structures and interaction parameters used by Simulis Thermodynamics for original UNIFAC and Mod. UNIFAC (Do) (on CD-ROM)
  • all the experimental data measured within this project (VLE, hE, 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, held every year in September in Oldenburg, the sponsors of the first category (see  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 typically in September) 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 or from any other provider.

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.
