Nalco Company
Chicago, IL
Intern: Chico Weber
Southern Illinois University, Edwardsville
Nalco is a leading manufacturer of water treatment chemicals. Nalco
also produces colloidal silica, which is used in the production of
paper, the clarification of juices and wines, the production of silicone
chips, and as a release agent in investment casting.
The intern was tasked with identifying opportunities to reduce waste
and energy use at the facility.
Results:
The intern made the following recommendations:
- Install induction lighting to replace the current HID lighting in nine
different warehouses. The projected annual savings for this is approximately
$31,500. The projected reduction in annual CO2 emissions from reduced
electricity use is 560 tons.
- Add flow meters on each of the condensate recovery units. There is no
direct energy savings, however the use of flow meters will improve fault
identification in condensate recovery lines as well as realize proper sizing
of condensate recovery units.
- Add insulation to three condensate recovery units. The projected annual
savings is $441. The projected reduction in annual CO2 emissions from reduced
natural gas use is 12 tons.
- Use Kill-A-Watt power meters for both break rooms and office spaces. The
projected annual savings is $174. The projected reduction in annual CO2 emission
from reduced electrical use is 3 tons.
- Add variable speed drives to exhaust fans in a number of warehouses. The
projected annual savings is $39,960. The projected reduction in CO2 emissions
from reduced electrical use is 708 tons a year.
- Develop a full process map of the facility. There are no direct energy savings,
however there are potential savings in identifying opportunities to optimize
processes and operations.
Estimated Total Annual Savings: $72,075
Estimated Total Annual CO2 Reduction: 1,283 tons
(1,271 tons from electrical use reduction)
(12 tons from natural gas use reduction)
