The seventh common meeting of the UNIFAC Consortium and the  DDBST User Meeting took place on Tuesday, 22. September 2009 and Wednesday, 23. September 2009, at the Carl von Ossietzky University of Oldenburg, Institute of Industrial Chemistry, Campus Wechloy.

The present status and the latest research activities on UNIFAC, mod. UNIFAC (Do) and PSRK were presented in short lectures. The company representatives had the opportunity to suggest possible future developments.
In the second part of the meeting the participants discussed proposals and practicable suggestions for the future developments of UNIFAC, mod. UNIFAC (Do), and PSRK at the research group. Another point at our time schedule was the discussion about the continuation of the Consortium after the retirement of Prof. Dr. Jürgen Gmehling in 2011.
In the evening all participants were invited to join the laboratory tour, followed by a dinner.
23 people from 17 companies have taken part in the meeting.
