Abstract:

Marine vessels contribute a significant portion of total pollutant gas and particulate matter emissions near ports and waterways across the United States. As such, current International Convention for the Prevention of Pollution from Ships (MARPOL), United States Federal, and California Air Resources Board emissions regulations dictate engine exhaust emission limits on CO, NOx, Total Hydrocarbons (THC), and Particulate Matter (PM) with SOx controlled via fuel sulfur content limits. These regulations also dictate a tiered schedule of increasingly stringent emissions limits be met in the future. The Marine Engine Testing and Emissions Laboratory (METEL) at Maine Maritime Academy (MMA) was created to assist and address the emission reduction needs of the marine industry due to regulatory requirements. Several emissions reduction projects are underway at METEL with a Continuous Emissions Monitoring System (CEMS) under development to quantify all gas and particulate emission improvements from laboratory testing and on board vessel testing at sea. The unique requirement of continuous emissions monitoring in a harsh marine environment requires rugged equipment on board a vessel capable of withstanding shock, vibration, and corrosion. For convenience, a simple calibration procedure is required with calibration stability over time. Fourier Transform Infrared (FTIR) spectroscopy is utilized in the system as a gas emissions monitoring device. FTIR has the potential to simultaneously quantify all currently regulated emissions and more than 100 of the 189 Hazardous Air Pollutants listed in the Clean Air Act Amendments of 1990 [1]. As such, the versatility of FTIR spectroscopy as a single source gas emissions measurement system will be evaluated as an alternative to meet marine emissions regulations. A Condensation Particle Counter (CPC) is additionally employed as a mature technology to measure exhaust particulate matter total number concentration. Additional strategies will be evaluated for measuring particulate matter total mass and particle size.
