Development of a Combined Oxidation System and Sea Water Scrubber to Reduce Diesel NOx Emissions from Marine Engines
To meet ambient air quality standards in the Houston-Galveston area requires substantial reduction of the NOx inventory. A major source of NOx at the ports is due to operation of marine engines in tugs and towboats. In addition, EPA’s proposed Tier 4 marine diesel engine emission standards are aimed at achieving a 90 percent reduction over baseline engines, something that has not been currently demonstrated in use with many approaches, including fuel reformulation, water injection, and retarding of timing. Proposed are the design, development and performance evaluation of a combined diesel oxidation catalyst (DOC) and seawater scrubber (SWS) after treatment system that has significant NOx reduction potential (~90 percent), along with co-beneficial reductions in PM, hydrocarbon (HC) carbon monoxide (CO) and sulfur dioxide (SO2).
