, SAMPLE COURSE SYLLABUS*
CHE 306 DESIGN SEPARATION PROCESSES
INSTRUCTOR: Professor Phillip C. Wankat
Office: FRNY 2037C
E-mail: (I usually answer quickly between 8 am and
5:30 pm. Use e-mail to communicate with Prof. Wankat for help.)
Office Hours: MWF 10:30-11:50 A.M. These times are reserved for 306 students.
On Wednesdays I will be in the computer lab from 1:30 to 3:20 P.M.
Other times by appointment only.
TA's – Office hours will be M 2:30 to 3:30, T 1:00 to 3:00 and W 1:00 to 2:30 in FRNY B142A
(starting second week of semester).
Prerequisites: Must have passed Mass & Energy Balances and Thermodynamics
TEXTBOOK: P.C. Wankat, Separation Process Engineering, 5th edition Prentice Hall, 2016.
Goals*: By the end of CHE 306 you should be able to:
1. Design flash distillation by hand and computer calculations;
2. Design distillation systems by hand and computer calculations;
3. Design extraction systems by hand and computer calculations;
4. Design membrane separation systems.
Importance: Separations constitute 50 to 90% of the cost (capital and operating) of chemical
plants. Distillation is the most important separation method in the chemical and petroleum
industries. Separations are one of the key items which delineate chemical engineering from the
other engineering disciplines.
Course The basic course outline* is:
Structure: 1. Introductory Material (1 week)
2. Flash Distillation (1 week)
3. Binary Distillation (2 weeks)
4. Multicomponent Distillation (2 weeks)
5. Complex Distillation (2 weeks)
6. Batch Distillation (1 week)
7. Distillation Design (1 week)
8. Absorption, Stripping, & Extraction (2 weeks)
9. Extraction (1 week)
10. Membrane separations (2 weeks)
The detailed course outline is attached. The typical weekly schedule will be:
Monday, Wednesday and Friday: 2 Lectures plus optional help.
Wednesday/Thursday: Computer Lab when scheduled
Since the schedule will sometimes deviate from this pattern, follow your detailed course outline.
Suggested Read book before class. Come to class prepared. There will be short
3
, Study quizzes to encourage preparation. New material will be presented in class
Procedure: as needed. Material in the book that is a review or is easy to understand
will not be lectured on. Ask questions if the book is not clear. After class,
reread the book. Make extensive notes on or in the book. Before each
exam summarize your notes on one page, and then reduce to 3x5 card
(double-sided) you can take into the exam.
The suggested way to do homework: First, work on all problems by
yourself. Then, meet with your study group to check answers and to
complete solution of more difficult problems. Ask for help once these
other efforts have failed. Finally, prepare your own solution to hand in if
the homework will be graded. It is important to solve a lot of problems
including homework that is not handed in.
You should spend 9 to 12 hours (including class & lab time) on this course
every week. If you are spending less, work more problems both
individually and in your study group.
Quizzes*: To encourage students to prepare for and attend class, there will be a series
of 10 short quizzes, which are 9% of the course grade. The lowest grade
will not count, which is equivalent to one free absence. After that an
absence will be a zero. Students who turn in a quiz with their name on it
and who stay the entire period and pay attention will automatically earn
50%. There will be no quiz make-ups and no taking quizzes late (Part of
the 50% for attendance is being on time – if you want this credit make
attendance a high priority. In other words, an interview at Purdue is NOT
a valid excuse for missing a quiz.) Missing 2 quizzes for plant trips will
cost 1% of the course grade – a small penalty. Writing another student’s
name on a quiz and turning it in for a grade will be treated as a form of
cheating. Graded quizzes will be passed out in labs.
Note: The number of quizzes and the % grade varies in the different schedules.
Homework*: There will be 8 homework assignments which are handed in. Students
who solve all of the problems are very likely to see their efforts rewarded
by higher test scores. The homework that is handed in will be 6% of the
course grade. The professor and TAs will grade one problem selected by
the professor and one problem selected by the student – write the problem
you want graded on the top of the assignment. Graded homework
assignments will be passed out in labs or will be available from the
secretary in FRNY 1029. Work in groups on homework is encouraged.
Turn in your own solution (not Xerox copy), but please list names of
group members on it (this speeds up grading).
Note: The number of homework and the % grade varies in different schedules.
Exams*: Arrange your schedule to be available for the night exams on Sept. 30 and
Nov. 4. The fourth exam, which is not a cumulative final exam, will be
during finals. Exams (including the lab test) are 70% of the course grade.
Your lowest exam will be 10% and the other three exams will count as
20% each. Exams (except the lab test) are closed book, but students will
