Texas A and M University


Dr. Economou's research focuses on the design, development, validation and application of state-of-the art models for the prediction of structure and physical properties of complex chemical systems that are of interest to oil & gas and chemical industry, to the protection of natural environment, and to the society, at large. Our models span a broad range of time and length scales, including: sub-molecular calculations using quantum mechanics techniques, molecular simulations using Molecular Dynamics and Metropolis Monte Carlo methods, and macroscopic engineering models such as equations of state rooted to Statistical Mechanics. Development of new models and predictions generated from these models are validated against experimental data from the literature or measured in our partner's laboratories. For our simulations, we are using the state of the art high performance computing facilities of Texas A&M University at Qatar. Research activities refer both to basic fundamental research as well as applied research. In all cases, the research projects in which we are involved are carefully selected with the aim to maximize our contribution to the international academic and industrial community. To this end, we collaborate with academic and industrial research groups in Europe and North America which are world leaders in their respective fields.  On-going research projects include: Molecular Modeling and Simulation: Thermodynamic and transport properties of water – carbon dioxide – salt systems, Gas hydrate multi-phase equilibria, Microscopic structure and physical properties of metal organic frameworks (MOFs) for isomer separation, Ionic liquids in pure and in mixture with supercritical CO2 and other gases, Sorption and diffusion of small molecules (CO, H2 and H2O) in heavy hydrocarbons, related to Gas-To-Liquid process for production of high value hydrocarbon fuels. Molecular Thermodynamics and Equation of State Development with Emphasis to Carbon Capture and Sequestration: Equations of state for electrolyte mixtures, Novel algorithms for multiphase equilibrium calculations including near critical conditions, Thermodynamic models for primary and derivative properties of CO2 mixtures, Equations of state for confined fluids.   Education PhD in Chemical Engineering, The Johns Hopkins University, Baltimore, MD, USA.  1992      Diploma of Chemical Engineering, National Technical University of Athens, Greece. 1987.
