CIEG 434: Air Pollution Control (3 hrs)
DESCRIPTION:
Overview of the sources, properties, effects,
and
regulations of particulate and gaseous air pollutants, with a focus on
the criteria pollutants and their precursors.
Introduction to the gas-cleaning equipment and processes commonly used
to
control emissions from industrial/stationary sources. These
include
gravitational and centrifugal separators, electrostatic precipitators,
bag
houses, particulate scrubbers, gas adsorption, gas absorption, and
thermal, catalytic, and biological oxidation. The strategies to
minimize
formation of combustion by-products will be discussed. Emphasis
will
be
placed on understanding the properties and behaviors of air pollutants
and
the
principles of the different emission control technologies.
PREREQUISITES:
CIEG233, CIEG305, and CHEG231 or equivalent.
TIME / PLACE:
Tuesday & Thursday, 2:00 - 3:15 p.m. / 350
DuPont Hall.

OFFICE HOURS:
Monday 1:30 - 3:00 p.m. You may also make appointments with the instructor by phone or email.TEXTBOOK: (Required)

REQUIREMENTS:
1. Homework Assignments (80 points = 10 points per assignment x 8 assignments)
You may work in groups of 2 to 4 (but no more than 4) on homework assignments. Each assignment is due one week from the day it is assigned. Points will be deducted for assignments submitted after the due date (see LATE POLICY below), unless a special request is submitted and approved by the instructor in advance. Each group only needs to turn in one assignment (but don't forget to include the names of all group members!) and all group members will receive the same grade.
2. Hourly Exams (60 points = 30 points each x 2 exams)
These exams will be open-book
and will be held in class, tentatively
on March 15 and
May 03. The first exam will cover
particulate matter
and its control, and the second exam will cover vapors and their
control.
You need to bring a calculator, a conversion table, and blank
paper.
You may also bring your lecture notes and the text. However, no cell/smart phone or any other
device that
can access either the phone network or wirelss internet is
permitted. All
such
devices must be turned off during exam or your exam will not be
accepted.
3. Final Exam (60 points)
The final exam will follow the same format as the mid-term
exams.
The final exam will be cumulative
and will cover ALL lectures, homework assignments,
hourly exams, and any guest
lectures if applicable. The final exam time and location will be
announced later in the spring as determined by the University.
ACTIVE PARTICIPATION:
Activities and efforts that contribute to understanding of the
subject
matter are encouraged and will be rewarded by extra "active
participation" points (up to 10 points/person/semester).
ATTENDANCE:
Attendance is not mandatory and no points will be deducted
due to
absence. However, absence and tardiness are not acceptable
reasons
for late assignments.
LATE POLICY:
Late homework assignments will
lose 20% (i.e., 2 points) per school day. After one week
from the due date, a
late
assignment is considered missing
and will not be accepted or graded (i.e., 20% x 5 days = 100%
deducted).
GRADING:
The total numbers of points are 200 based on the requirements.
If you earn a total of
170 points or more, you will receive an A or A-
150 points or more, you will receive a B+, B, or B-
130 points or more, you will receive a C+, C, or C-
120 points or more, you will receive a D
< 120 points, you will receive an F
