Khaled A.M. Gasem
Amoco Chair and Professor
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
Director of the Chemical Engineering Graduate
Program and the Associate Director of Integrated
Petroleum Environmental Consortium (IPEC).
Dr. Gasem
has been actively involved in experimental,
theoretical and process thermodynamics for over 25
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, and environmental engineering. Dr. Gasem is known for bringing to
the classroom a boundless energy and enthusiasm. Currently, he teaches
transport phenomena and graduate courses in thermodynamics and research
methods.
RESEARCH INTERESTS:
Phase Equilibria
Thermodynamics and Process Development 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. The
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.
Current research goals of the Thermodynamics Group
(Khaled, Rob Robinson, three teams of graduate
students and postdoctoral associates) 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.
