AB - The purpose of this research is to evaluate different BC measurement techniques and to utilize these to evaluate the effectiveness of an exhaust gas after-treatment scrubber installed on a marine auxiliary engine in reducing emissions of SOx, PM (which include BC and ultra-fines less than 2.5 μm PM2.5) and other pollutants at different engine loads. Scrubbers are primarily designed to remove SOx emissions with most manufacturers claiming 98-99% reductions in SOx. However manufacturers’ claims for PM2.5 reductions vary widely, from 30-85% or more (4). Little information is available on the effectiveness of scrubbers to remove BC. Preliminary results from this research suggest that for the scrubber technology evaluated, it is capable of reducing total PM from 40 to 50% and averaged 45% across the scrubber, but varied from 10% to 80% for BC depending on load. The results suggest BC reductions are a strong function of engine load for the scrubber technology evaluated in this study. The results of this report provide recommendations for BC measurement, improve our understanding of BC emissions from ocean going vessels, and evaluate the effectiveness of a typical marine PM scrubber control device.

Abstract
The purpose of this research is to evaluate different BC measurement techniques and to utilize these to evaluate the effectiveness of an exhaust gas after-treatment scrubber installed on a marine auxiliary engine in reducing emissions of SOx, PM (which include BC and ultra-fines less than 2.5 μm PM2.5) and other pollutants at different engine loads. Scrubbers are primarily designed to remove SOx emissions with most manufacturers claiming 98-99% reductions in SOx. However manufacturers’ claims for PM2.5 reductions vary widely, from 30-85% or more (4). Little information is available on the effectiveness of scrubbers to remove BC. Preliminary results from this research suggest that for the scrubber technology evaluated, it is capable of reducing total PM from 40 to 50% and averaged 45% across the scrubber, but varied from 10% to 80% for BC depending on load. The results suggest BC reductions are a strong function of engine load for the scrubber technology evaluated in this study. The results of this report provide recommendations for BC measurement, improve our understanding of BC emissions from ocean going vessels, and evaluate the effectiveness of a typical marine PM scrubber control device.
