2 The Problem

3 The PROBLEM (continued) Depiction of Various Ship Stack Configurations The Exhaust Capture System must Can Accommodate Various accommodate Stack Shapes various stack geometries

4 The PROBLEM (continued) The system must be able to treat various fuel types, handle various exhaust flows and exhaust temperatures

5 The Solution

6 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 Based System Shore-Based System Multi-Capture and Treatment System

7 Emissions Treatment Subsystem Picture of the Actual System Demonstrated and Tested in Roseville, California

8 Successful Demonstration Program The objective of the tests at Union Pacific Railroad s 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

9 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

41 Under Lessons Leaned: AMECS Improvements 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 n 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 w evaluate other systems. We developed a much better understanding of rail yard operations s and the type of exhaust capture system that would most likely work without interfering with railroad operations.
