Jürgen Schmidt has worked as a safety expert for more than 25 years at Hoechst AG, Frankfurt and BASF SE, Ludwigshafen, Germany. Since 2002 he lectures in Process and Plant Safety at the Karlsruhe Institute of Technology, Germany. Prof. Schmidt studied Process Engineering at the University Bochum, Germany, and at the Texas A&M University, USA. His main fi elds of interest are smart safety concepts (combining safety and economics), two-phase gas/liquid flow, safety devices and cyclone separators, high pressure fluid flow and condensation in natural gas pipelines. He has published more than 100 scientifi c articles in these areas.
Prof. Schmidt is member of the steering committee of ProcessNet?s Safety Engineering Section (a group of Dechema) in Germany and chairs the working group 'Safe Design of Chemical Plants'. Currently he leads ISO's standardization working party for 'Flashing liquids in safety devices'. In addition he is member of the board in the European DIERS User Group. He has received numerous awards from the Industry
and the European Process Safety Centre.
