François MaréchalPh D. in engineering Chemical process engineer
Researcher and lecturer in the field of computer aided process and energy systems engineering.
Lecturer in the mechanical engineering, electrical engineering and environmental sciences engineering in EPFL.
I'm responsible for the Minor in Energy of EPFL and I'm involved in 3 projects of the Competence Center in Energy and Mobility (2nd generation biofuel, Wood SOFC, and gas turbine development with CO2 mitigation) in which i'm contributing to the energy conversion system design and optimisation.
Short summary of my scientific carrer
After a graduation in chemical engineering from the University of Liège, I have obtained a Ph. D. from the University of Liège in the LASSC laboratory of Prof. Kalitventzeff (former president of the European working party on computer aided process engineering). This laboratory was one of the pioneering laboratory in the field of Computer Aided Process Engineering.
In the group of Professor Kalitventzeff, I have worked on the development and the applications of data reconciliation, process modelling and optimisation techniques in the chemical process industry, my experience ranges from nuclear power stations to chemical plants. In the LASSC, I have been responsible from the developments in the field of rational use of energy in the industry. My first research topic has been the methodological development of process integration techniques, combining the use of pinch based methods and of mathematical programming: e.g. for the design of multiperiod heat exchanger networks or Mixed integer non linear programming techniques for the optimal management of utility systems. Fronted with applications in the industry, my work then mainly concentrated on the optimal integration of utility systems considering not only the energy requirements but the cost of the energy requirements and the energy conversion systems. I developed methods for analysing and integrating the utility system, the steam networks, combustion (including waste fuel), gas turbines or other advanced energy conversion systems (cogeneration, refrigeration and heat). The techniques applied uses operation research tools like mixed integer linear programming and exergy analysis. In order to evaluate the results of the utility integration, a new graphical method for representing the integration of the utility systems has been developed. By the use of MILP techniques, the method developed for the utility integration has been extended to handled site scale problems, to incorporate environmental constraints and reduce the water usage. This method (the Effect Modelling and Optimisation method) has been successfully applied to the chemical plants industry, the pulp and paper industry and the power plant. Instead of focusing on academic problems, I mainly developed my research based on industrial applications that lead to valuable and applicable patented results. Recently the methods developed have been extended to realise the thermoeconomic optimisation of integrated systems like fuel cells. My present R&D work concerns the application of multi-objective optimisation strategies in the design of processes and integrated energy conversion systems.
Since 2001, Im working in the Industrial Energy Systems Laboratory (LENI) of Ecole Polytechnique fédérale de Lausanne (EPFL) where Im leading the R&D activities in the field of Computer Aided Analysis and Design of Industrial Energy Systems with a major focus on sustainable energy conversion system development using thermo-economic optimisation methodologies. A part from the application and the development of process integration techniques, that remains my major field of expertise, the applications concern :
Rational use of water and energy in Industrial processes and industrial production sites : projects with NESTLE, EDF, VEOLIA and Borregaard (pulp and paper).Energy conversion and process design : biofuels from waste biomass (with GASNAT, EGO and PSI), water dessalination and waste water treatment plant (VEOLIA), power plant design (ALSTOM), Energy conversion from geothermal sources (BFE). Integrated energy systems in urban areas : together with SCANE and SIG (GE) and IEA annexe 42 for micro-cogeneration systems.
I as well contributed to the definition of the 2000 Watt society and to studies concerning the emergence of green technologies on the market in the frame of the Alliance for Global Sustainability.
Nava SetterNava Setter completed MSc in Civil Engineering in the Technion (Israel) and PhD in Solid State Science in Penn. State University (USA) (1980). After post-doctoral work at the Universities of Oxford (UK) and Geneva (Switzerland), she joined an R&D institute in Haifa (Israel) where she became the head of the Electronic Ceramics Lab (1988). She began her affiliation with EPFL in 1989 as the Director of the Ceramics Laboratory, becoming Full Professor of Materials Science and Engineering in 1992. She had been Head of the Materials Department in the past and more recently has served as the Director of the Doctoral School for Materials.
Research at the Ceramics Laboratory, which Nava Setter directs, concerns the science and technology of functional ceramics focusing on piezoelectric and related materials: ferroelectrics, dielectrics, pyroelectrics and also ferromagnetics. The work includes fundamental and applied research and covers the various scales from the atoms to the final devices. Emphasis is given to micro- and nano-fabrication technology with ceramics and coupled theoretical and experimental studies of the functioning of ferroelectrics.
Her own research interests include ferroelectrics and piezoelectrics: in particular the effects of interfaces, finite-size and domain-wall phenomena, as well as structure-property relations and the pursuit of new applications. The leading thread in her work over the years has been the demonstration of how basic or fundamental concepts in materials - particularly ferroelectrics - can be utilized in a new way and/or in new types of devices. She has published over 450 scientific and technical papers.
Nava Setter is a Fellow of the Swiss Academy of Technical Sciences, the Institute of Electrical and Electronic Engineers (IEEE), and the World Academy of Ceramics. Among the awards she received are the Swiss-Korea Research Award, the ISIF outstanding achievement award, and the Ferroelectrics-IEEE recognition award. In 2010 her research was recognized by the European Union by the award of an ERC Advanced Investigator Grant. Recently she received the IEEE-UFFC Achievement Award (2011),the W.R. Buessem Award(2011), the Robert S. Sosman Award Lecture (American Ceramics Society) (2013), and the American Vacuum Society Recognition for Excellence in Leadership (2013).
