RESEARCH INTERESTS

Membrane Separation

Extensive simulation of membrane permeators is being conducted. Experiments are under investigation on a novel facilitated transport membrane system for separation of oxygen from air, carbon dioxide from gas mixtures, hydrogen and methane from gasification products using coordination complexes is under investigation. Simulation of membrane reactors utilizing membrane separations coupled with chemical reactions, for several reactions has been conducted. Experimental investigation of the process using ceramic, metallic, and inorganic membranes is under investigation.

Process Synthesis

Extensive work has been conducted on the synthesis of reaction paths, arrangement of simple and complex distillation columns, synthesis of reactors, heat exchanger network synthesis, and development of process flowsheets.

Process Simulation, Control and Optimization

Studies are being conducted on the development of decentralized control structures, real time simulation of process dynamics, and global optimization of chemical process systems.

Coal Combustion

Computer simulation of coal combustors, especially circulating fluidized beds, is being conducted. Experimental studies inlude cold models and actual bench-scale coal combustors utilizing entrained designs. Nonintrusive sensing of the combustion environment using optical techniques is also being studied.
