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.
The objectives of this course are to learn modern systematic design strategies for steady state chemical processing systems and at the same time to gain a functional facility with a process simulator (Aspen) for design, analysis, and economic evaluation. A process is constructed stepwise, with continuing discussion of heuristics, recycle, purge streams, and other process conditions. Aspen is used for design and analysis of the process units. From the viewpoint of the process simulations, the course is divided into four categories: Component, property and data management; Unit operations; System simulation; and Process economic evaluation. The equations used by the simulator are discussed as well as convergence methods, loops and tear streams and scrutiny of default settings in the simulator. The factored cost method and profitability measures are reviewed and compared to simulator results. Work on a capstone design project is begun in the last section of the course.
A laboratory course designed to illustrate and apply chemical engineering fundamentals. The course covers a range of experiments involving mass, momentum and energy, transport processes and basic unit operations such as distillation, stripping and multi-phase catalytic reactions.
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.

CHE 501:Mass and Energy Balances, Stagewise Operations
This course serves as an introduction to chemical engineering for those with no previous training in the field. Among the topics covered are mass and energy balances, and equilibrium stagewise operations.
This course supplements the clasical undergraduate thermodynamics course by focusing on physical and thermodynamic properties, and phase equilibria. A variety of equations of state, and their applicability, are introduced as are all of the important liquid activity coefficient equations. Customization of both vapor and liquid equations is introduced by appropriate methods of applied mathematics. Vapot-liquid, liquid-liquid, vapor-liquid-liquid and solid-liquid equilibria are considered with rigor. Industrial applications are employed. A variety of methods for estimating physical and thermodynamic properties are introduced. Students are encouraged to use commercial software in applications. The course concludes with an introduction to statistical thermodynamics.
Analysis of batch and continuous chemical reactions for homogeneous, heterogeneous, catalytic, and non-catalytic reactions; influence of temperature, pressure, reactor size and type, mass and heat transport on yield and product distribution; design criteria based on optimal operating conditions and reactor stability will be developed.
Integration of the principles of biochemistry and microbiology into chemical engineering processes; microbial kinetic models; transport in bioprocess systems; single & mixed culture fermentation technology; enzyme synthesis, purification & kinetics; bioreactor analysis, design and control; product recovery and downstream processing.
Applications of the laws of thermodynamics to solutions, electrolytes and polyelectrolytes, binding, and biological systems; statistical thermodynamics is developed and applied to spectroscopy and transition state theory; and chemical kinetics of simple and complex reactions, enzyme and heterogeneous catalysis, and theories of reaction rates.
This course will provide a fundamental understanding, and the application of emerging and current approaches to reaction engineering and catalysis in the pharmaceutical and fine chemical industries. The course will focus on promising technologies such as enzymatic catalysis and bioreactor design, chiral synthesis and kinetics, multiphase reactions, and microreactor technology with emphasis throughout on industrially relevant reactions.
This course is designed for both science and engineering students who want to contribute to the development and implementation of processes for production of important renewable energy sources. In this course, students will learn the fundamental concepts of important biofuels and the current state-of -the-art technology for their production along with economics, environmental impact, and policy issues. Benefiting from this course, students would be able to evaluate ways for converting feedstocks to biofuels by both biochemical and thermochemical methods and integrate conceptual design of a biofuel process. As a fundamental cross-discipline course, topics are comprehensive yet introductory and require the minimal prerequisite learning in chemistry and thermodynamics.
