CIEG 434: Air Pollution Control (3 hrs)



DESCRIPTION:

Overview of the sources, properties, effects, and regulations of particulate and gaseous air pollutants.  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 (scrubbing), and thermal, catalytic and biological oxidation.  The strategies to minimize combustion by-product formation will be discussed.  Emphasis will be placed on understanding the properties and behaviors of pollutants and the principles of different control technologies.

CIEG233, CIEG305, and CHEG231 or equivalent.
 

TIME / PLACE:

Tuesday & Thursday, 2:00 - 3:15 p.m. / 350 DuPont Hall.

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 homework assignments submitted after the due date (see LATE POLICY below), unless special requests are made and approved by the instructor in advance.  Each group only needs to submit one assignment (don't forget to include the names of all group members!), and every group member will receive the same grade.

2. Mid-Term Exams (60 points = 30 points each x 2 exams)

The two exams will be open-book and will be held in class, tentatively on March 26 and May 07.  The first exam will cover particulate matter and its control, and the second one will cover vapors and their control.  You should bring a calculator, a conversion table, and blank paper.  You may also bring your lecture notes and the textbook.

3. Final Exam (60 points)

The format of the final exam will be the same as the mid-term exam.  The final exam will be cumulative and will cover everything, including lectures, homework assignments, the two exams, and any guest lectures if applicable.  The time/date for the final exam will be announced later in the semester.

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 lateness 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, the late assignment 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-
110 points or more, you will receive a D+, D, or D-
< 110 points, you will receive an F
