UNIT OPERATIONS Fall 2020

Catalog Data: CHEE 3462: Unit Operations Cr. 4 Prerequisites: CHEE 3333 (Chemical Engineering Thermodynamics II). Textbook: Seader J.D., Henley E.J., and Roper D.K., “Separation Process Principles”, 3rd Ed. 2013, John Wiley & Sons, Inc., ISBN 1118139623, 9781118139622, or 9780470481837 The course website on Blackboard will be updated regularly with homework assignments, handouts, and other information. Results of homework assignments, quizzes, and exams must be uploaded to Blackboard. Please be familiar with software that allows photos of calculations to be digitized and uploaded to Blackboard. Course Description and Goals: The goals of this course are to develop a fundamental understanding of unit operations, improve critical thinking skills, and gain practical process simulator experience working on concepts relevant to the course material. These goals will be achieved through a course/laboratory structure that promotes problem solving through reasoning and creative thinking. Course material will draw upon previous topics in mass and energy balances, thermodynamics, fluid dynamics, and heat and mass transport (concurrent). The basic concepts covered in these topics will be a foundation for solving a wide variety of problems with an emphasis on separations. The textbook for this course facilitates learning through clearly written derivations and examples. Students are strongly encouraged to use the additional resources available at the university library or the “Student http://bcs.wiley.com/heCompanion Site” at the link bcs/Books?action=index&bcsId=10311&itemId=1119257336 . In the laboratory portion of the course, the students will learn how to use Aspen Plus software to perform unit operation calculations. After a few introductory modules, the students will construct an entire process flow sheet for a petrochemical process over the course of several weeks. Information on how to access to the Aspen software is at the end of this syllabus. Instructor:

Links for Aspen v11 All students must have access to Aspen v11 for the laboratory portion of the course. There are three methods of accessing this software: 1. At the ECC lab 2. From your computer through a virtual ECC connection 3. Download and install on your own computer Method (3) is by far the best option, but not all computers are able to run Aspen. Mac’s will not work. Older computers seem to have more problems. The installation process is quite painful, but you will be much happier if you can succeed with this option!

Instructions for virtual ECC connection: https://1drv.ms/b/s!ArOSsd9i_Wz7qRvR5bYq2HTOvwy7?e=gNCnF7 Be sure to follow the instructions on how to save files – or you will lose your work!

Face Covering Policy (required for courses with a face-to-face component)

To reduce the spread of COVID-19, the University requires face coverings on campus including classrooms for both faculty and students. Face coverings must cover your mouth and nose and be worn throughout the class session. A mask with a valve is not considered an adequate face covering and should not be used, as it can expel exhaled air, increasing the risk to others. Eating or drinking during class is discouraged and is not an excuse for removing the face covering for any extended length of time. For additional information on the use of face coverings, please see Face Covering FAQs. Failure to comply with the requirement to wear a face covering in class will result in your being asked to leave the classroom immediately and a disciplinary referral through the Dean of Students Office. Requests for accommodations relating to the face covering policy may be directed to the Center for Students with DisABILITIES (CSD).

Required Daily Health Self-Assessment (required for courses with a face-to-face component)

Your presence in class each session means that you have completed a daily self-assessment of your health/exposure and you: Are NOT exhibiting any Coronavirus Symptoms Have NOT tested positive for COVID-19 Have NOT knowingly been exposed to someone with COVID-19 or suspected/presumed COVID-19 If you are experiencing any COVID-19 symptoms that are not clearly related to a pre-existing medical condition, do not come to class. Please see COVID-19 Diagnosis/Symptoms Protocols for what to do if you experience symptoms and Potential Exposure to Coronavirus for what to do if you have potentially been exposed to COVID-19.
