Engineering Evaluation of Capture and Control Efficiency

Delta Air Quality Services, Inc. (Delta) has been contracted by the Clean Air Engineering-Maritime, Inc. (CAEM) to perform engineering evaluation testing on dockside emissions capture and control system for cargo ship auxiliary generator emissions. The tests were conducted to evaluate the capture and control efficiency of components of the system. From these measurements, overall system performance can be derived.

The tests were performed using a trailer mounted 2 kW diesel generator to simulate OGV auxiliary generator emissions, the actual hood/transfer line/crane assembly that will be used in future OGV demonstrations, and a Tri-Mer air pollution control unit that is scale-able to match the volumes of emission gases to be encountered from whatever OGV source targeted for dockside control.

The evaluation had two primary goals:

  1. To evaluate the collection efficiency of the hood/transfer line/crane assembly, and
  2. To determine the removal efficiency of the Tri-Mer system for nitrogen oxides (NOx), carbon monoxide (CO), and particulate matter (PM).
