The Solution
Emissions Control Technology
ACTI’s Emissions Control Technology consists of
two types of systems:
• Advanced Locomotive Emissions Control
System (ALECS) designed to capture and treat
the exhaust emissions from railroad locomotives
• Advanced Maritime Emissions Control
System (AMECS) designed to capture and treat
the exhaust emissions from ocean-going vessels
– Barge-Based System
– Shore-Based System
– Multi-Capture and Treatment System
Emissions Treatment Subsystem
Picture of the Actual System
Demonstrated and Tested in
Roseville, California
Successful Demonstration Program
• The objective of the tests at Union Pacific
Railroad’s J. R. Davis rail-yard in Roseville,
California was to demonstrate ALECS
capability to:
-
Remotely attach to a railroad locomotive
around the exhaust opening
-
Capture the exhaust gas and direct it via
the overhead manifold system into the
Emissions Treatment Subsystem
Successful Demonstration Program
(continued)
-
Maintain attachment and exhaust capture
while the railroad locomotive is underway
within designated area within the rail
yards
• The test of ALECS was a success, meeting
all the goals described above and more
• The same treatment system is used on
AMECS

SUMMARY
Advanced Maritime Emissions
Control System (AMECS®)
Advantages:
• No ship modification required
• Substantial Reduction of Harmful Pollutants
– Removal percentages of sulfur dioxide (SO2),
particulate matter (PM), oxides of nitrogen NOX)
all above 95%, depending on fuel type
– Over 60% removal of Hydrocarbons
• Can capture and treat exhaust emissions while ships
are berthed and anchored waiting to be berthed
• Provides a Cost-Effective solution

AMECS Improvements
Under Lessons Leaned:
The following two improvements are under consideration as a result of the
Demonstration and Testing Program in Roseville, California
• Create one common housing partition between the Selective Catalyst
Reduction (SCR) Reactor and the Thermal Management System (shown in
the next slide). This would increase thermal efficiency and reduce the system
cost.
• Continuous Emissions Monitoring System (CEMS); the system deployed
seems to require a greater amount of technical skill then we believe is
necessary. In addition, the system cost seems to be high. We will evaluate
other systems.
• We developed a much better understanding of rail yard operations and the
type of exhaust capture system that would most likely work without
interfering with railroad operations.
