Chemical & Biomolecular Separations

4.0

credits

Average Course Rating

(3.63)

This course covers staged and continuous-contacting separations processes critical to the chemical and biochemical industries. Separations technologies studied include distillation, liquid-liquid extraction, gas absorption, membrane ultrafiltration, reverse osmosis, dialysis, adsorption, and chromatography. Particular emphasis is placed on the biochemical uses of these processes and consequently on how the treatment of these processes differs from the more traditional approach.

57 The best aspects of this course included the variety of assignments, the instructor’s enthusiasm, and the computer projects on distil ation. One student felt the coding assignments seemed arbitrary. Another student felt the instructor was often unprepared. Suggestions included providing more explicit instructions for projects, allowing students more time with the midterm, and giving students feedback on a regular basis. Prospective students should know this course is time-consuming and work-intensive, but that help is always available.

The best aspects of this course were the humorous and unconventional teaching style of the instructor, the material covered, and the helpful TAs. There was only one midterm and the textbook was straightforward. The worst aspects of the course were the slow feedback on homework and exams, the disorganization of the instructor, and the instructor’s unconventional teaching methods. Suggested improvements to the course included more timely feedback on homework, better organized lectures and class progression, and access to problem solutions. Prospective students should know they wil need to read the textbook and do a good deal of independent learning.

The best aspects of the class included learning material that is useful for chemical engineering, and the engaging professor whose energy and frequent questions made the class interactive and entertaining. Students found exams to be fair and reflective of the information covered in class. Many students claimed that lectures and notes were disorganized, as well as the homework assignments and deadlines. Students would have appreciated receiving more prompt grades and feedback on their assignments and focusing more on examples during class time. Prospective students should be prepared to attend every lecture and to utilize the textbook effectively.
