The Lecturer

Jürgen Rarey is a physical properties and chemical process simulation specialist with a diploma in chemistry and PhD in chemical engineering from the Technical University of Dortmund (Germany). He held a researcher position at the University of Oldenburg (Germany) from1989 to 2019 in the group of Prof. Jürgen Gmehling, co-founded DDBST GmbH (www.ddbst.com) and acted as managing director from 1989 to 2017. Jürgen Rarey conducted his research on predictive models for important physical properties within his honorary professor position (2005-2018) at the University of Kwazulu-Natal in Durban (South Africa) in cooperation with Prof. Deresh Ramjugernath.

In addition he was temporarily employed in industry within specific projects and was involved in a number of international research cooperations.

Since 2016 Jürgen Rarey is a faculty member at ChEPS-KMUTT, Thonburi (Thailand), where he teaches regular courses on chemical thermodynamics.

Besides his experimental and theoretical work, Jürgen Rarey has been teaching 5 to 10 courses per year for academia and industry on chemical thermodynamics (since 1989), process simulation (CHEMCAD and Aspen Plus) (since 1995) and chemical process development (since 2012, 2 months full day).

Since November 2020, Jürgen Rarey is permanently living in Nakhon Ratchasima, Thailand. In 2021 he joined the newly founded Rareytec Co. Ltd. in order to legally work on laboratory equipment development and teach online courses in the country.

Besides his teaching at KMUTT, Thonburi, he continues many years of close cooperation and international student exchange with the School of Biotechnology at Suranaree University of Technology (SUT) (Prof. Apichat Boontawan) nearby and is a member of the International Advisory Committee for the yearly TIChE conference and member of the Thai Institute of Chemical Engineering and Applied Chemistry.

Jürgen Rarey has authored more than 50 publications in international journals and co-authored 4 books of the DECHEMA Chemistry Data Series and the textbook “Chemical Thermodynamics for Process Simulation”, Wiley (2012, 2019). His work received about 5200 citations.

Selected research interests include:

  • Development of automated equipment for determination of phase equilibria and physical properties.
  • Simultaneous correlation of mixture data (software development).
  • Chemical process simulation, process optimization and visualization.
  • Predictive models for pure component and mixture behavior.
  • COSMO-RS-type models.
  • Simulation and optimization of biorefinery processes.
