Khaled A.M. Gasem
Edward E. Bartlett Chair and Head
BACKGROUND:
Dr. Gasem holds a B.Sc. degree from the
University of California at Berkeley (1976),
M.Sc. from Colorado School of Mines (1979), and
a Ph.D. from Oklahoma State University (1986).
He is the Head of the School of Chemical
Engineering, the Director of the Chemical
Engineering Graduate Program, the Associate
Director of
Integrated Consortium for Energy and the
Environment (ICEE) and the co-founding
member of the
Coal-Seq
Consortium.
Dr. Gasem has been actively involved in
experimental, theoretical and process
thermodynamics for over 30
years. He has extensive experience in phase
equilibrium thermodynamics, thermophysical
property prediction, and process
development/simulation.
TEACHING INTERESTS:
He has taught courses in thermodynamics,
transport phenomena, process simulation,
research methods, and
environmental engineering.
RESEARCH INTERESTS:
Equilibrium phase behavior and the resultant
thermodynamic properties are a manifestation of
molecular interactions. Therefore, efforts to
account for such interactions in developing
thermodynamic models are essential. Our
thermodynamics research program encompasses
studies in theory, experimentation, algorithm
development, and computer simulations to permit
effective modeling of the phase behavior of
targeted applications. Further, thermodynamic
property prediction is an interplay among the
theoretical framework stemming from the laws of
thermodynamics, equation-of-state (EOS) models
that describe the phase behavior of the
molecular species involved, and the numerical
algorithms implemented. Accordingly, successful
predictions of thermodynamic properties are
realized only when clear objectives are stated,
appropriate methods are used, and a critical
evaluation of the results is conducted.
The current goals
of our research group
are to:
-
Use theoretically-based, molecular calculations
to “design” optimum chemicals for targeted
applications using neural networks and genetic
algorithms
-
Develop accurate predictive models for
describing the adsorption behavior of gas
mixtures encountered in coalbed methane
production and CO2 sequestration
-
Develop accurate EOS models and robust
algorithms to describe the phase behavior of
multiphase, multicomponent equilibrium systems
of interest in the energy sector
-
Develop products and processes for targeted
applications
Several dedicated laboratories support the
thermodynamics research activities, including
those for measuring high-pressure vapor-liquid
equilibria (VLE), low-pressure VLE, asymmetric
gas solubilities, infinite-dilution activity
coefficients, water-hydrocarbon mutual
solubilities, and high-pressure adsorption. In
addition, to facilitate product and process
development, the Thermodynamics Group has
generated / assembled specialized databases for
asymmetric mixtures, natural gas processing,
extractive solvents, water-hydrocarbon mutual
solubilities, alternative refrigerants,
high-pressure adsorption, and molecular
structures.
