Cloud Chamber Scrubber Case Studies
Case Study #1: Glass Furnace Exhaust for Container
|
| Technology Update (Case Study #1) | |
The Tri-Mer UltraCat ceramic filter system is now the technology of choice for this application. It supersedes the Cloud Chamber Scrubber in performance and at a lower cost. Tri-Mer now has six projects on glass furnace emissions in the U.S. that cover the range of glass and furnace types. The latest system controls glass furnace emissions for PM, SOx, and NOx using the UltraCat catalyst filter system. Tri-Mer ceramic filter systems have become the industry choice for float, container, and glassware projects, and both air-fuel and oxy-fired furnaces. |
| Technology Update (Case Study #4) | |
The Tri-Mer UltraCat ceramic filter system is now the technology of choice for this application. It supersedes the Cloud Chamber Scrubber in performance and at a lower cost. Tri-Mer now has large projects in ceramics manufacturing in the U.S. that remove PM, SO2, HCl, HF and NOx in an all-in-one UltraCat catalyst filter system. |
| Technology Update (Both Case Studies #6 & #7) | |
The Tri-Mer UltraCat ceramic filter system is now the technology of choice for this application. It supersedes the Cloud Chamber Scrubber in performance and at a lower cost. The application is large stationary diesel such as generators, ships-at-port and other large sources. It is not applicable to automotive or truck diesel. Tri-Mer has diesel results for PM, SO2, and NOx all removed by an all-in-one UltraCat catalyst filter system. |
| Technology Update (Case Study #6) | |
The Tri-Mer UltraCat ceramic filter system is now the technology of choice for this application. It supersedes the Cloud Chamber Scrubber in performance and at a lower cost. The application is large stationary diesel such as generators, ships-at-port and other large sources. It is not applicable to automotive or truck diesel. Tri-Mer has diesel results for PM, SO2, and NOx all removed by an all-in-one UltraCat catalyst filter system. |
Tri-Mer Cloud Chamber Scrubber (CCS) with integrated SCR at the trainyard
in Roseville, California. Roseville is near Sacramento.
Tri-Mer Corporation, developer of the CCS technology, teamed with Advanced
Clean-up Technologies, Inc. (ACTI) a California environmental clean-up company, to work with
California and U.S. air quality authorities on a full-scale demonstration of the CCS for diesel
emissions from locomotives that are immobile or moving only short distances within a rail yard.
The objective was to demonstrate the ability of the CCS to remove fine and submicron particulate
matter (PM) and SOx. Selective Catalytic Reduction (SCR) equipment was integrated with the
CCS to provide NOx removal. The demonstration testing was deemed very successful and a
Media Day event was held at the site by the governmental authorities in August 2006.
The official report isavailable from the Placer County Air Pollution Control District under the project name Advanced Locomotive Emissions Control System (ALECS).
Tri-Mer Corporation provided all the air pollution control technology, including integration of
the SCR. Equipment engineering and manufacturing was completed at its Michigan factory.
Tri-Mer was also responsible for installation and demonstration of the technology.
After using its own advanced particulate characterization equipment to calibrate the CCS system,
the government agencies contracted with an independent third party testing company and laboratory
to provide conventional testing and analysis of PM, SO2, and NOx for the final report.
With the successful demonstration test, the CCS is now regarded as the first technology
to demonstrate high removal efficiencies when operating at the flow volumes typical for
large diesel engines. Implementation of the CCS technology is anticipated at several locations.
A similar test is planned for the Port of Long Beach on emissions from the diesel generators of
ships at dock. The CCS technology is already being applied to numerous other difficult
applications. Units have been operating 24/7 for more than eight years with low operating costs,
and very low maintenance costs.
The following summary in italics is excerpted from the official report:
The Union Pacific Railroad’s J.R. Davis Rail Yard in Roseville, California, is a major center for
locomotive maintenance and repair, as well as for assembling and reassembling trains of freight
cars. Over 90 percent of all Union Pacific rail traffic in Northern California goes through the yard.
Locomotive operations at the rail yard have been determined to be a significant source of
emissions of diesel particulate matter (PM) and other pollutants. An agreement between the
Placer County Air Pollution Control District (PCAPCD) and the Union Pacific Railroad Company
(UPRR) includes a mitigation plan for reducing PM emissions from the rail yard.
Part of this plan is an assessment of the use of stationary air pollution control equipment to
capture and treat emissions from motionless locomotives while idling or undergoing engine
load tests during maintenance. The Advanced Locomotive Emission Control System (ALECS)
comprises a set of stationary emissions control equipment connected to an articulated bonnet.
The bonnet is designed to capture locomotive exhaust, delivering it to the ground-based
emission control system via ducting. The hood remains attached while the locomotive is
moving slowly along the track to the extent of the ducting. The emission control equipment
comprises a sodium hydroxide wash to remove sulfur dioxide (SO2), a triple cloud chamber
scrubber for PM removal, and a Selective Catalytic Reduction (SCR) reactor to reduce
oxides of nitrogen (NOx).
The ALECS is designed to treat exhaust flows between 2,000 and 12,000 standard cubic
feet per minute (scum). The former is approximately the exhaust flow from a locomotive at idle,
while the latter is approximately the exhaust flow from a line-haul locomotive at throttle notch
8 (full power).
The ALECS proof-of-concept was a public-private collaborative project involving the PCAPCD,
U.S. Environmental Protection Agency (EPA), Sacramento Metropolitan Air Quality Management
District (SMAQMD), UPRR, Advanced Cleanup Technologies Inc. (ACTI), the South Coast Air
Quality Management District (SCAQMD), the California Air Resources Board (CARB), and the
City of Roseville. Engine, Fuel, and Emissions Engineering, Inc. (EF&EE) was contracted by the
SCAQMD to conduct emission measurements before and after the ALECS.
Emission measurements were performed on two locomotives: a General Motors Electro-Motive
Division GP38 and a General Electric C39-8 (Dash 8). The GP38 has a 2000 horsepower
two-stroke diesel engine, and is typically used for switching and local service. The Dash-8
has a 3900 horsepower four-stroke engine, and is normally used for line-haul freight service.
Tests were performed with the locomotives motionless at notch 1, notch 3, notch 5, and notch
8 power settings, and while moving slowing back and forth along a small section of track. See www.placer.ca.gov/apcd for the complete executive summary and full report.
1 The anomalous low average PM value (in comparison to the other PM control efficiencies)
has been investigated by ACTI, but it could not be explained. The data is included in the
overall average calculation for completeness.
Tri-Mer Corporation has conducted tests on a different diesel source at their testing facility in
Michigan with similar results: removal efficiencies for PM between 94% and 98% with removal
of SO2 consistently over 99%. Tri-Mer and the government agencies were very pleased with the
Roseville results. The CCS has been validated for implementation on large diesel sources.
As with other CCS applications, these results and other scientific data gathered during the
testing period will lead to further enhancements of the Cloud Chamber technology.

hood allowed limited locomotive movement, bringing emissions to the CCS. Stationary
repair facilities are also under consideration. Another application is ships at docks operating
their diesel genrators for on-board power.
