Jürgen Gmehling

Jürgen Gmehling (2010)

Jürgen Gmehling (born January 13, 1946 in Duisburg) is a retired German professor of technical and industrial chemistry at the Carl von Ossietzky University of Oldenburg.

Biography

His career started with an apprenticeship as a laboratory assistant at the Duisburg copper works before he studied chemical engineering at the engineering school in Essen and then chemistry in Dortmund and Clausthal. He received his diploma from the University of Dortmund in 1970 and his PhD (Dr. rer. nat., inorganic chemistry) in 1973. After this he worked as a scientific coworker in Dortmund before he became a private lecturer and, after his habilitation, an assistant professor.

Gmehling was appointed a full professor for technical chemistry at the University of Oldenburg in 1989 and retired in 2011.

Fields of research

Gmehling's main focus is the process development. This includes the development of software for process synthesis and process simulation as well as measurement, collection, and estimation of thermophysical properties of pure components and component mixtures. The following list summarizes fields of his scientific work but is in no way complete.

Measurements

Data collection

Gmehling began in the 1970s with the systematic evaluation of the scientific literature, aiming to build a data bank for vapor-liquid equilibria. These data were needed for the development of a new method for the prediction of activity coefficients named UNIFAC. This data bank is still named the Dortmund Data Bank,.[4]

Development of estimation and correlation models

Gmehling developed with colleagues models for the estimation of several thermodynamic and thermophysical properties:

Software development

The following implementation of his methods are also developments:
