Polymers for Gas Separation Membranes: Where are We Now?
Speaker: Dr. Maria Giovanna Buonomenna
Registration Fee: 65 US$/Person
Time Length: ~60 Min[More]
Description: The key parameters for gas separations employing membranes are the permeability of a specific component of the gas mixture and the selectivity. Membrane gas separation employing polymeric membranes has been commercially used since the 1970s generating a significant amount of academic and industrial research activity. It was recognized that an empirical upper limit (the well-known “upper bound”) for the combined selectivity and permeability exists : the selectivity generally decreases with increasing permeability of the more permeable gas component. Molecular sieve membranes with well-defined uniform pore structure would be considered to be the true upper bound limit for polymeric membranes. Recently this upper bound has been updated for relevant gas separations by microporous rigid polymeric membranes . In this Webinar, an analysis of recent findings for industrially relevant gas pairs, such as CO2/CH4, CO2/N2 is given.
Speaker: M. G. Buonomenna (Salerno, 1975), graduated in Chemistry in 1998 (110/110), obtained the license and status of Professional Chemist in 1999 (100/100). She was awarded a Research Fellowship in Membrane Materials and Operations in 1999 from the Institute on Membrane and Technology (ITM) (former IRMERC)-National Research Council of Italy (CNR) and a PhD in Chemical Engineering and Materials in 2005 from the University of Calabria. In February 2014 and for the second time in October 2018 she obtained the qualification of Associate Professor in Chemical Fundamentals of Technologies from the Italian Ministry for Instruction, University and Research (MIUR). Her research activities relate to membrane science and technology for sustainable processes. She is author of more than 60 scientific papers in peer-reviewed international journals, 1 book, more than 90 contributions published in conferences proceedings, 10 chapters of scientific books, editor of 1 book on advanced membrane materials, guest-editor of 9 Special Issues in peer-reviewed international journals, and member of the Editorial Boards for a number of international peer reviewed journals. She has been an Invited Speaker in numerous international conferences. She serves as reviewer for several international scientific journals and as Expert Evaluator for International Funding Agencies.
Batch Distillation Modeling, Optimization, and Control: Past, Present, and Future
Speaker: Dr. Urmila Diwekar
Registration Fee: FREE
Time Length: ~60 Min[More]
Description: The recent increase in the production of high-value-added, low-volume specialty chemicals and biochemicals has generated a renewed interest in batch processing technologies. Batch distillation is a critical unit operation in the batch processing industry and is widely used. The flexibility of batch distillation combined with the inherent unsteady nature of the process poses challenging design and operation problems. This talk presents the overview of simulation, optimization, and control starting from the first theoretical development in 1902 with Rayleigh equation. This talk covers: 1. The various operating modes of batch distillation; 2.Examines challenges involved in rigorous modeling; 3.need for the hierarchy of models; 4.optimization and optimal control problems encountered; 5. recent developments related to complex columns, complex systems, and uncertainties, and the role of computer-aided molecular design in batch distillation 6. Real-world case studies of difficult separations
Carbon Footprint Reduction for the Process Industry
Speaker: Prof. Dominic Foo
Registration Fee: 65 US$ / Person
Time Length: ~90 Min[More]
Description: Emissions of greenhouse gases (GHGs) such as CO2 and CH4 from industrial activities have long been known to be major contributors to global warming. This trend has led to significant interest in the increased use of low carbon footprints technologies, as well as in retrofitting existing facilities to reduce GHG emissions. In this talk, generic graphical tool known as carbon footprint diagram is introduced to assist industrial practitioners for decision making in reducing carbon footprint for their manufacturing processes. The carbon footprint diagram allows management-based (e.g., material selection) and technology-based solutions (e.g. process retrofits for energy conservation, heat recovery, etc.) to be examined, while simultaneously considering technical and economic constraints.
