- ECH 1: Design of Coffee – An Introduction to Chemical Engineering (3 Units)
- Prerequisites: None. Intended for non-majors.
Many people are aware that chemical engineering exists as a profession – but few people have a firm idea about what chemical engineers actually do on a daily basis. This class is intended to serve as a non-mathematical introduction to how chemical engineers think, as illustrated by elucidation of the process of roasting and brewing coffee. The instructors will provide qualitative overviews of the basic principles of engineering analysis and design, and then guide the students in corresponding laboratory experiments testing the effect of design choices on the sensory qualities of coffee. In this manner, students will learn that even a process with only two “chemicals” – coffee beans and water – requires careful consideration of key physical concepts that are actually ubiquitous in chemical engineering. Why coffee? As we will discuss in this class, making coffee is actually a quintessential operation in chemical engineering. A raw material – in this case green coffee beans – undergoes a variety of chemical reactions in a roaster. The roasted beans are then ground to a specific size to optimize the extraction or “mass transfer” of caffeine and flavor molecules into the liquid phase, and a filtration step provides the final separation to ultimately deliver the cup of coffee. This class will start students down the path of thinking about coffee – and other processes or products – the way a chemical engineer does. Toward that end, the class will be organized around weekly laboratory experiments that each focus on a core chemical engineering concept. In weeks 1 and 2, the students will partially disassemble a drip coffee maker, and learn how the coffee maker can be considered as a series of “unit operations” that each accomplish a specific goal. In weeks 3 and 4, the students will learn how to roast green coffee beans using kitchen-scale roasters. The students will learn about the core reaction engineering concepts of “conversion” and “selectivity”, and importantly they will be able to taste the consequences of various roast profiles. Weeks 5 through 8 will then feature experiments exploring various design choices regarding grind size, temperature, pressure, filtration, with corresponding discussion about the underlying principles of mass transfer, fluid mechanics, thermodynamics, and colloid science. Week 9 will introduce basic engineering economics, comparing “break-even” curves for roasting your own coffee versus buying daily coffees from Starbucks. Finally, the class will culminate in week 10 with a design competition featuring a blind taste test of the students’ custom roasted brews. - ECH 5: Introduction to Analysis and Design in Chemical Engineering (3 Units)

Prerequisites: ECH 142.
A degree in chemical engineering offers a variety of career paths, including petrochemical, pharmaceutical, pulp and paper, and food industries. In North America, food scientists are not exposed to core engineering disciplines and chemical engineers are one of the professions hired to fill the food process engineer position. However, chemical engineering students are rarely exposed to the application of chemical engineering principles to food processes. By providing the opportunity for students to acquire a deeper knowledge and the skill sets on the food industry, they would possibly be more comfortable in choosing the food and beverage sector as a career. Therefore, the objective of this course is to provide an introduction to food industry and use real word problems for students to learn the theory learned in core chemical engineering courses to food industrial processes. We will explore different concepts relevant to food industry in the laboratory. Fundamental skills that students will employ are organic chemistry, basic fluid mechanics and rheology, ultra violet visible (UV-Vis) spectroscopy, thermodynamics, measurement of emulsion stability with a rheometer, refractometer, heat and mass transfer such as unsteady-state conductive heat transfer and Fick’s law. Lectures will supply introduction of new concepts significant to food processing and relevant background to put the laboratories into context. Assessments will be based on analysis of quantitative results, briefly weekly reports, and one project design.Week 1: Introduction to food components.
Week 2: Manipulating phase transition. Construct a phase diagram for ricotta cheese.
Week 3: Food texture. Rheology analysis and pasting curves of different starch solutions. Pump design.

- ECH 172(V): Chemical Process Safety Fundamentals
Prerequisites: ECH 141, ECH 152B (can be concurrent), or consent of instructor.
This is a practical course that seeks to give students interested in a career in chemical process engineering a solid foundation in chemical process safety concepts. This course includes concepts not covered elsewhere in the chemical engineering curriculum (or only briefly) including industrial health & hygiene, chemical compatibility, and risk analysis. This course also demonstrates the practical application of skills learned in chemical core courses in process safety – for example the application of transport to the development of toxic hazard source and dispersion models, and the application of thermodynamics to identifying potential flammable mixtures. This course uses past chemical plant disasters as teaching tools. Students completing this course are expected to be equipped to use risk and safety considerations as a part of their professional decision-making process.
