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.
