Graduate Seminar Announcement - Prof Shinji Hasebe
Purdue University School of Chemical Engineering Graduate seminar series Prof. Shinji Hasebe Department of Chemical Engineering Kyoto University, Japan "Process Systems Engineering for Realizing Micro Chemical Plants" November 12, 2013 9:00-10:15 a.m. FRNY G140 Reception at 8:30 a.m. in Henson Atrium Abstract: The production of high value-added products requires the precise control of temperature, flow pattern and residence time. It is difficult for conventional plants to satisfy these requirements. Many researchers have discussed the availability of the micro-systems for production. However, to realize the micro chemical plants, the contribution of PSE is essential. In this lecture, the design and control problems of micro chemical plants are discussed from the viewpoint of process systems engineering. One of the dominant characteristics of the design problem of micro devices is that the shape of the device should be included in the design variables in addition to the volume of the device. Three types of systematic shape design methods will be explained using case studies. Because of the difference of the characteristic size, micro chemical plants require different instrumentation and control systems from conventional chemical plants. Some control systems, which are suitable for the micro chemical plants are demonstrated. In real micro chemical plants, the blockage of the channels is the crucial problem for long stable operation. In the presentation, the latest blockage detection system for parallelized micro process is explained. Bio: Professor Hasebe received his B.E., M.E. and Ph.D. degrees in chemical engineering from Kyoto University in 1976, 1978 and 1984. He became an assistant professor of the Department of Chemical Engineering at Kyoto University in 1981. After the experience of lecturer and associate professor, he is a full professor in the Department of Chemical Engineering since 2003. He is Vice Chairman of the Committee for International Academic Exchange of the Graduate School of Engineering at Kyoto University since April 2010, and organized the NEDO national project named "Development of Microspace and Nanospace Reaction Environment Technology for Functional Materials" as project leader. His research areas are design and operation of micro chemical plants, supply chain management, synthesis of environmentally benign processes and the synthesis of separation processes.
Purdue University School of Chemical Engineering Graduate seminar series Prof. Rakesh Agrawal School of Chemical Engineering, Purdue University "Engineering a Sustainable Energy Future" November 19, 2013 9:00-10:15 a.m. FRNY G140 Reception at 8:30 a.m. in Henson Atrium Abstract: In the long run, it is likely that all the basic human needs will be met by renewable sources like solar energy. However, there are several challenges associated with harness, storage and use of solar energy to meet our daily needs for food, chemicals, heat, electricity and transportation. In a sustainable future, all these usage must coexist. We will first present some results from our energy systems modeling highlighting the synergistic interactions that exist for transportation sector and production of chemicals. This will be followed by a brief discussion and analysis of candidate processes to produce hydrogen from solar energy and our modeling results for energy storage at giga Watt-hour levels. An exciting aspect of producing fuels and chemicals from biomass is learning to produce the array of molecules that we need with minimum process transformation steps and energy use while maximizing biomass carbon recovery. In this aspect, recent advancements at Purdue by a team of chemists, biologists and chemical engineers will be presented. We will show the new pathways and the associated catalysts that have been developed for the production of fuel and chemicals. On the sun to electricity front, we will present highlights of our research on thin film solar cells via nanocrystal ink based route. We will discuss process and technical solutions leading to power conversion efficiencies that are among the highest for Cu(In,Ga)Se2 and Cu2ZnSnSe4 based solar cells by solution based routes. Finally, we will touch upon the continuing advancements made in the traditional fields such as separations that will still play a vital role in the processes slated for any sustainable energy future.
