Project Summary

 

Exploration of novel and advanced brine management options is challenging because of the lack of high-fidelity simulators that accurately capture solution thermodynamics and kinetics to optimize separation efficiency and processing options. Existing process simulation software are black box, and inflexible for customization. Here, we propose the development of a new library of open models, including processing blocks and property models for water treatment practitioners. The overarching goal of this project is to leverage the developments and powerful computational engine of  Pyomo in the user-friendly environment of IDAES and the ProteusLib module to develop open-source libraries of property models for highly concentrated aqueous and heterogeneous electrolyte solutions,  embedded in block model libraries for processing and separations. These libraries will then be used in optimization-based algorithms for simultaneous process synthesis and intensification of brine treatment options. Lab-scale validation of the properties and dynamics of the separation and processing options is also planned. The final project deliverable is a rich library of thermodynamics and process models along with optimization algorithms for the design and synthesis of brine treatment processes. This project is expected to disrupt practices of process synthesis and optimization of water-treatment facilities in a software that is open to all NAWI users and can be integrated with parallel efforts such as LCA in Water TAP3 and the ProteusLib IDAES module. Openness in the models also provides complete access to the  (thermodynamic or process) model equations, that can be leveraged in advanced optimization  algorithms for large-scale, robust, dynamic optimization or optimal process synthesis

George Bollas

george.bollas@uconn.edu

Dr. George Bollas is the Director of the Institute for Advanced Systems Engineering (IASE) at the University of Connecticut. He is an Associate Professor with the Department of Chemical and Biomolecular Engineering at the University of Connecticut, a process design expert and winner of the prestigious NSF CAREER Award and the ACS PRF DNI Award. He received B.E. and Ph.D. degrees from the Aristotle University of Thessaloniki in Greece and then worked as a postdoctoral research associate at the Chemical Engineering Department of MIT. At UConn, he is leading efforts to develop and explore novel system representations (steady state and dynamic models) of thermal fluid systems (TFS) in equation-oriented environments that allow system dynamic optimization, sensitivity and uncertainty analysis, fault detection and optimal control. Dr. Bollas is also the director of the Process Design Simulation and Optimization Laboratory (PDSOL). The lab pursues a balanced approach to experimentation guided by robust modeling and simulation of chemical processes, including experimental design, process scaling and control.

 

Matthew Stuber

Dr. Stuber holds a Bachelor of Chemical Engineering degree from the University of Minnesota – Twin Cities and a PhD in Chemical Engineering from MIT.  His graduate research focused on the development of theory and algorithms for advanced formal methods in robust design and optimal design under uncertainty.  Specifically, he developed tools necessary to solve challenging problems in rigorous performance and safety verification of process systems for extreme and hostile environments.  Dr. Stuber’s post-doctoral work was as a scientist, engineer, and entrepreneur developing an optimized concentrating solar-powered desalination process, launching a start-up company, and piloting the desalination technology for agricultural wastewater reuse in California’s agricultural sector.  Driven by the exciting opportunities in pure and applied research, Dr. Stuber decided to make his way back to academia joining the faculty at UConn.

Dr. Stuber’s research focuses on theory and methods for optimization-based approaches to solving challenging problems in energy, healthcare, and food and water security.  Dr. Stuber emphasizes the full-pipeline view of bringing fundamental developments and discovery to implementation and commercialization for greatest impact.  Recent projects involve rigorous model validation, large-scale global optimization, and optimal design for water and food security in underrepresented communities.
