EGR and Membrane Separation for IMO Tier III Compliance
- 63 Downloads
Complying with NOx emissions legislation using equipment that is integral to the engine is an attractive solution for engine operators. WTZ Rosslau has researched the NOx reduction potentials of both EGR and air separating membranes in combination with fuel-water emulsion on diesel engines, paying close attention to the formation of exhaust smoke and particulate matter as well as NOx.
The introduction of IMO Tier III in Emission Control Areas (ECAs) requires a drastic reduction of oxides of nitrogen (NOx) in the exhaust gases of marine diesel engines. At the Wissenschaftlich-Technisches Zentrum für Motoren- und Maschinenforschung Rosslau, Germany, the potentials of exhaust gas recirculation (EGR) and air separating membranes have been investigated using single-cylinder diesel research engines. The two methods are generally suitable for obtaining NOxemissions levels of 2 g/kWh. However, additional measures are necessary to ensure acceptable engine exhaust smoke levels and...
