CHE 210:Process Analysis
An introduction to the most important processes employed by the chemical industries, such as plastics, pharmaceutical, chemical, petrochemical, and biochemical. The major emphasis is on formulating and solving material and energy balances for simple and complex systems. Equilibrium concepts for chemical process systems will be developed and applied. Computer courseware will be utilized extensively. |

CHE 332:Separation Operations
The design of industrial separation equipment using both analytical and graphical methods is studied. Equilibrium based design techniques for single and multiple stages in distillation, absorption/stripping, and liquid-liquid extraction are employed. An introduction to gas-solid and solid-liquid systems is presented as well. Mass transfer considerations are included in efficiency calculations and design procedures for packed absorption towers, membrane separations, and adsorption. Ion exchange and chromatography are discussed. The role of solution thermodynamics and the methods of estimating or calculating thermodynamic properties are also studied. Degrees of freedom analyses are threaded throughout the course as well as the appropriate use of software. Iterative rigorous solutions are discussed as bases for Aspen simulation models used in Design VI. |

CHE 423:Engineering Design VII
Senior Design provides, over the course of two semesters, collaborative design experiences with a problems of industrial or societal significance. Projects can originate with an industrial sponsor, from an engineering project on campus, or from other industrial or academic sources. In all cases, a project is a capstone experience that draws extensively from the student's engineering and scientific background and requires independent judgments and actions. Advice from the faculty and industrial sponsors is made readily available. The projects generally involve a number of unit operations, a detailed economic analysis, simulation, use of industrial economic and process software packages, and experimentation and/or prototype construction. The economic thread initiated in Design VI is continued in the first semester of Senior Design by close interaction on a project basis with E 421. Leadership and entrepreneurship are nourished throughout all phases of the project. The project goals are met stepwise, with each milestone forming a part of a final report with a common structure. |

| | Research & Education |  |
| | Research | | Research interests include mathematical modeling of transport processes, and development of 3-dimensional finite element method based codes for simulation of flow, heat, and mass transfer in complex geometries, polymer processing, and rheological characterization of complex fluids. Strong research background in experimental fluid flow, heat and mass transfer, and surface characterization of materials including contact angle measurement, determination of interfacial/surface tension, and interfacial stability on solid substrates. His current research focus is on developing an understanding of the role of complex surface effects in transport phenomena in micro- configurations, utilizing his prior experience in transport processes in macro- configurations as a platform. Some of the FEM codes he developed have been used to design successfully processing equipment for composite energetic materials for the US Army, and the Navy. Philips Netherlands, the GAF Materials Corporation, and the Petroleum Research Fund have also funded his research work. |
