Questions & Answers

Q: What is the purpose of the class?

The purpose of the class is to teach students how to apply basic sciences, such as physics, math, chemistry, and biology, to the conversion of raw materials into valuable products. This includes refining crude oil, manufacturing polymers, designing biomedical devices, and more.

Q: How did chemical engineering originate?

Chemical engineering originated with the need to refine crude oil into useful products. The process of refining oil involves converting complex hydrocarbon molecules into more manageable liquids and gases that meet market demands. Over time, chemical engineering has expanded to other industries and applications.

Q: What are some examples of products that chemical engineers can produce?

Chemical engineers can produce a variety of products, such as gasoline, jet fuel, polymers, pharmaceuticals, fine chemicals, ceramics, and biomaterials. They can also be involved in pollution control devices, electronics, and the food industry.

Q: How can chemical engineering be used to protect and improve the environment?

Chemical engineers play a crucial role in remediating and cleaning up environmental pollution. They can develop methods to clean up contaminated groundwater, degrade toxic wastes in the air, and design zero-emission systems. Chemical engineers also work on pollution control devices, such as catalytic converters, to reduce emissions from vehicles and industries.

Q: What other career opportunities are available for chemical engineers?

Chemical engineers can work in various industries, including oil refineries, petrochemicals, electronics, pharmaceuticals, and more. They can work on novel materials, biomaterials, nanostructures, and composites. They can also be involved in the design of batteries, fuel cells, and control systems. Additionally, chemical engineers can focus on protecting and improving the environment through pollution control and remediation efforts.

Q: How is the class structured?

The class focuses on conservation principles, such as mass and energy conservation. It involves studying basic sciences, such as chemistry, physics, and biology, and applying them to real-world examples and case studies. The class also emphasizes problem-solving and hands-on learning, with project design and problem sets throughout the course.

Q: What are some case studies that will be covered in the class?

Some of the case studies that will be covered in the class include designing a platelet donation machine, apheresis, designing a high fructose corn syrup plant, and understanding pharmacokinetics using a nicotine patch. These case studies allow students to apply their knowledge to practical examples and enhance their understanding of chemical engineering principles.

Q: How can students access course materials?

Course materials, including lecture notes, problem sets, and references, are available on the course website on CourseWorks, a platform used by Stanford University. Students can access these materials and refer to them for studying and completing assignments.

Q: What is the grading structure like for the class?

The class has a grading structure that includes problem sets, exams, and a final project. Problem sets account for 30% of the grade, while exams account for 40% (20% for each midterm exam) and the final project accounts for 30%. The class aims to help students succeed and perform well while also ensuring they have a good learning experience.

Q: Are there any additional resources available for students?

In addition to the professor, there are teaching assistants (TAs) available to help students with their problem sets and provide additional support. The TAs have office hours where students can seek assistance, and their contact information is provided on the course website. There are also references available in the library for further reading on specific topics discussed in the class.
