Case Study #7:
Diesel Exhaust Emissions / Ships at Port 
To test the efficiency of the Tri-Mer CCS® Cloud Chamber Scrubber for the capture
of diesel emissions from ships at port, a bonnet/capture device developed by
ACTI (Advanced Cleanup Technologies, Inc.) is fitted over the exhaust stack. Impressive Reductions in Ship Diesel Pollution
Announced at Port of Long Beach Media Event Technology sets new standard for the treatment of
high volume stationary source diesel emissions A media event was held June 19, 2008 at the Port of Long Beach, CA to announce the results
of tests for cleaning diesel emissions using Cloud Chamber Scrubber technology developed by
Tri-Mer Corporation. The emissions tests covered all sources originating from ships at dock,
including auxiliary engines, boilers, and on-board power generators. Barry Wallerstein, Executive Director of the South Coast Air Quality Management District (AQMD) was
a prominent speaker; the roster also included Wayne Nastri, Region 9 Administrator for the U.S. EPA. The Cloud Chamber Scrubber (CCS) achieved reduction rates that effectively establish a new
standard for the treatment of high-volume diesel emissions. Performance efficiencies of the CCS,
detailed at the event, were high for all target pollutants:
- Particulate Matter 98% reduction
- SO2 98% reduction
- NOx 99% reduction
The Tri-Mer CCS uses patented, “charged droplet” technology to remove particulate and SO2
pollutants. Diesel particulate is less than 0.1 micron in size and is one of the most difficult
particulates to control. The CCS employs a special pre-conditioning process that allows
particles to be captured by the charged droplets while simultaneously removing the SO2. NOx is treated by a selective catalytic reduction (SCR) module which is a factory-integrated option
of the CCS system. PM and sulfur that might otherwise impede catalyst efficiency and service life
are removed prior to NOx treatment, so exceptional results are consistently achievable. Tri-Mer Corporation provided all the air pollution control technology, including controls and
integration of the SCR. Equipment engineering and manufacturing was completed at its
Michigan factory. Tri-Mer was also responsible for helping coordinate installation and
demonstration of the technology. Advanced particulate characterization equipment was used to calibrate the CCS system.
The ship exhaust was brought to the dock-side CCS system using a capture device developed
by ACTI (Rancho Dominguez, CA), the environmental company that hosted the media day.
The government agencies and other stakeholders at the Port contracted with an independent
third party testing company and laboratory to provide standard testing and analysis of PM,
SO2, and NOx for independent verification. With the successful demonstration test at the Port of Long Beach, and a similar demonstration
on diesel locomotive emissions at Union Pacific (Roseville, CA), CCS is now regarded as the
first technology to prove consistent high removal efficiencies when operating at the flow
volumes typical for large diesel engines.

Background: Diesel Pollution Originating
with Commercial Ships Cargo ships, some of which can emit more diesel exhaust per day than 12,000 automobiles,
are responsible for much of the air pollution in the region. They are a leading source of nitrogen
oxides, sulfur oxides and particulate matter, which have been linked to premature deaths,
respiratory illnesses and global warming in the LA basin and many other port areas. Moreover, commercial ships, enroute and at port, release more sulphur dioxide particulate than
all of the world’s cars, trucks and buses combined, according to a study released in March by the
International Council on Clean Transportation, and quoted in a Wall Street Journal article
Nov. 27, 2007. The study further found that ships produced an estimated 27% of the world’s
nitrogen oxide emissions – a huge percentage by any standard. In November, 2007, a peer-reviewed study in the American Chemical Society’s journal,
Environmental Science and Technology estimated that under-regulated air pollution from
ships results in 60,000 deaths from lung cancer and cardiopulmonary disease each year,
primarily along trade routes in Asia and Europe.
Background: CCS Cloud Chamber Scrubber
The Cloud Chamber Scrubber treats PM2.5, fine, submicron, ultrafine, and condensable
particulate as well as PM10 and more coarse particles. Simultaneously, CCS removes any
gas treatable by a wet scrubber, including HCl, NO2, SO2, Cl2, NH3 as well as HF, H2SO4,
HNO3, ammonia and amine compounds. This is important because, for the first time,
one device can handle particulates and corrosive fumes simultaneously. CCS is based on new patented discoveries in electrofluidics. It offers proven submicron
performance at efficiencies typically greater than 99% thanks to its capability to efficiently
“grow” and capture particles smaller than 0.1 micron.
It is also highly energy-efficient, requiring just 10 watts per 1000 cfm to charge the water droplets,
plus moderate pump power for water recirculation. It operates with ultra-low water usage.
CCS generates less than 1.5” w.g. pressure drop across the system. Gas temperature,
particle solubility, resistivity, and reactivity have minimal affect on performance.
CCS accommodates heavy loadings and is not sensitive to load flux.
