Learning Objectives:
1. Design and analyze separation processes using mass & energy balances and phase equilibria;
2. Describe and analyze steady-state convective and diffusive mass -transfer phenomena, including the use of mass
transfer coefficients;
3. Describe and analyze quasi steady-state and/or transient mass -transfer phenomena, including the use of mass
transfer coefficients;
4. Apply knowledge of mass transfer and/or separations to potential process and/or product safety concerns.

POLICIES AND PROCEDURES
COMMUNICATION: Dr. Li and the TA will use e-mail to communicate with the class. Check your e-mail daily.
ATTENDANCE: Participation is a vital part of the course. Attendance at all classes is required. For a full
statement of the university attendance policy see https://policies.ncsu.edu/regulation/reg-02-20-03-attendanceregulations/. If you know you will miss a class for a legitimate reason, please let the instructor know ahead of time
via email.
GRADING:
Homework 30%
Exams (3) 70%
EXAMS: There will be two mid-term exams and one final exam. Exams will be based principally upon the
course notes and homework. All exams are open-book/open-notes (some closed-book/closed-Notes portions may
be included). Students may not share notes, books or any other materials during the examination.
Missed Exams: If you miss an exam without prior approval or a certified medical excuse, you will be
given a grade of zero (0) unless Dr. Li agrees to give you a Make-Up Exam. This will be determined on a case-bycase basis depending upon the reason for missing the exam. You shall discuss this with Dr. Li before missing the
exam. If you miss the Final Exam without a valid excuse, a zero (0) will be averaged into your grade.
HOMEWORK: Students must complete and turn-in homework assignments individually. You may work in
groups to complete the assignments, but you may not have identical solutions for problems (see the Academic
Integrity Policy).
Homework Format: Electronically submit your homework in a PDF file with A4 sized pages. Begin
EACH problem on a NEW page and BOX the final answer. Put your name, the homework set number
and date on the first page and sign your name underneath. Your signature testifies that you neither gave nor
received unauthorized aid for your work. Points will be taken off for not following these instructions.
Write neatly! If the graders cannot read your work, then it is unlikely you will receive credit despite your
time and effort.
Homework must be submitted, via Moodle through the Gradescope link, before the specified
deadline (due before class).
Late Homework: Completed late assignments will receive a point deduction of -10%. Late solution sets
will be accepted up to 9:35 on the Monday after the due date. Any submission after this will not receive any
credits.
One homework assignment may be assigned during the last week of class.
REGRADES: If you believe that an error was made in grading an exam or homework set, write a short
justification of your claim, and append it to the original exam or homework set in question. Email to the TAs and
copy Dr. Li. The TAs and Dr. Li will review your concern and respond to you, but note that the entire exam or
homework set will be re-graded, not just the problem in question, in order to ensure consistency and fairness. The
“statute of limitations” for submitting such claims is one week after the exam or homework is returned.
LAPTOP AND CELL PHONE USE: Please refrain from texting, instant messaging, e-mailing, surfing the
Internet, playing games, etc. during class time since it prevents your active participation in the class. Please put cell
phones on silent during class. Cell phones must be turned off and put away during exams.
ACADEMIC INTEGRITY: Students should refer to the University policy on academic integrity found in the Code
of Student Conduct (found at https://policies.ncsu.edu/policy/pol-11-35-01/). It is the instructor’s understanding and
expectation that the student's signature on any test or assignment means that the student contributed to the
assignment in question (if a group assignment) and that they neither gave nor received unauthorized aid. Authorized
aid on an individual assignment includes discussing the interpretation of the problem statement, sharing ideas or
approaches for solving the problem, and explaining concepts involved in the problem. Any other aid would be
unauthorized and a violation of the academic integrity policy. Examples of unauthorized aid include but not
limit to consulting or providing tests from previous years (without the explicit consent of the instructors) and
possession of a solution manual (or equivalent) in the preparation of homework assignments. Any computer work
submitted must be completed on your own personal computer or from your own EOS account to avoid confusion
2
about the origin of the file, and no sharing of files in anyway is allowed. All cases of academic misconduct will be
submitted to the Office of Student Conduct. Students found guilty of academic misconduct will be subject to a
zero for that course component (e.g. a zero for the homework portion of the final grade), or a failing grade in the
course, depending on the nature of the violation. In addition, if you are found guilty of academic misconduct in the
course, you will be on academic integrity probation for the remainder of your years at NCSU and may be required to
report your violation on future professional school applications. It’s not worth it!
STUDENTS WITH DISABILITIES: Reasonable accommodations will be made for students with verifiable
disabilities. In order to take advantage of available accommodations, students must register with Disability Services
for Students (DSS) at 1900 Student Health Center, Campus Box 7509, 515-7653: https://dro.dasa.ncsu.edu/ and
should see Dr. Li with the appropriate paperwork from DSS. North Carolina State is subject to the Department of
Health, Education, and Welfare regulations implementing Section 504 of the Rehabilitation Act of 1973. Section
504 provides that: "No otherwise qualified handicapped individual in the United States. . . shall, solely by reason of
his handicap be excluded from participation in, be denied the benefits of, or be subjected to discrimination under any
program or activity receiving Federal financial assistance." This regulation includes students with hearing, visual,
motor, or learning disabilities and states that colleges and universities must make "reasonable adjustments" to ensure
that academic requirements are not discriminatory. Modifications may require rescheduling classes from
inaccessible to accessible buildings, providing access to auxiliary aids such as tape recorders, special lab equipment,
or other services such as readers, note takers, or interpreters. It further requires that exams actually evaluate students'
progress and achievement rather than reflect their impaired skills. This may require oral or taped tests, readers,
scribes, separate testing rooms, or extension of time limits.
COIVD RELATED ITEMS: To accommodate student needs and potential course disruptions related to COVID19, portions of this syllabus are subject to change.
Due to the Coronavirus pandemic, public health measures have been implemented across campus. Students should
stay current with these practices and expectations through the Protect the Pack website
(https://www.ncsu.edu/coronavirus/). The sections below provide expectations and conduct related to COVID-19
issues.
Health and Participation in Class
We are most concerned about your health and the health of your classmates and instructors/TAs.
•
•
If you are in quarantine, have been notified that you may have been exposed to COVID-19, or have a
personal or family situation related to COVID-19 that prevents you from attending this course, please
connect with your instructor to discuss the situation and make alternative plans, as necessary.
If you need to make a request for an academic consideration related to COVID-19, please talk with your
instructor for the appropriate process to make a request.
Health and Well-Being Resources
These are difficult times, and academic and personal stress is a natural result. Everyone is encouraged to take care of
themselves and their peers. If you need additional support, there are many resources on campus to help you:
•
•
•
•
Counseling Center (https://counseling.dasa.ncsu.edu/)
Health Center (https://healthypack.dasa.ncsu.edu/)
If the personal behavior of a classmate concerns or worries you, either for the classmate’s well-being or
yours, we encourage you to report this behavior to the NC State CARES team:
(https://prevention.dasa.ncsu.edu/nc-state-cares/about/)
If you or someone you know are experiencing food, housing or financial insecurity, please see the Pack
Essentials Program (https://dasa.ncsu.edu/pack-essentials/).
