Workpackage 5: Exhaust Emission Reduction
A wide range of emission reduction methods were examined and evaluated in the I.P. HERCULES (A) project. It was shown that some of these innovative methods cannot be applied to large marine engines, whilst others have substantial potential.
The Workpackage 5: Exhaust Emission Reduction will consider both NOx and particulate pollutants. Regarding particulate matter components, the detailed investigation of emissions under various operating conditions will enable to extend the know-how in characterizing these components. It will then be possible to develop improved models of soot and particulate formation for various fuel qualities, to be used in combustion simulations. This knowledge will also support designs for removal of particulate matter and SOx via scrubbing. Regarding NOx, the application of extreme EGR for ultra-low emissions will be experimentally investigated on a large test engine, in combination with the application of a novel EGR boiler for energy recovery.
Further, the new concept of Combustion-Gas-Recirculation (CGR) will be examined via a prototype unit. Regarding aftertreatment, the limits of operation and boundary conditions for on-board Selective Catalytic Reduction (SCR) will be investigated. Finally, the evaluation of combination of technologies for maximum NOx reduction will be performed on a prototype engine. The WP5 has close links with WP2: Combustion and also links to WP1: Extreme Parameters Engines, WP3: Turbocharging and WP8: Electronics & Control.
