11 DEECON: Innovative After-Treatment System for Marine Diesel Engine Emission Control

12 The DEECON Project 7 th European Framework Programme Cooperation, Transport Project ABSTRACT The aim of this project is to create a new, modular, on-board, after-treatment unit that combines different sub-units, each of which is optimized to remove a specific primary pollutant (SOx, NOx, PM and VOC ) and is designed to allow an easy and fast retrofit of existing ships but also can be fitted to new ships of the future. The main goal of this new integrated system is the reduction of the environmental footprint of ships through the achievement of a state-of-the-art removal of the target pollutants aimed to reduce their emission factor well below the limits imposed by the current and future regulation. The technology developed within DEECON aims at the: Reduction of NOx > 98% Reduction of PM 90% in number; > 99% in weight Reduction of HC > 80% Reduction of CO > 80% Reduction of SOx > 98%

13 The DEECON approach Particulate matter removal: WET ELECTROSTATIC SCRUBBER, WES: Advanced technology for submicronic particle capture and SOx absorption SOx removal SEA WATER SCRUBBER, SWS: SOx, soluble VOC absorption NOx removal HYBRID NON-THERMAL PLASMA TECHNOLOGY (EB+MW NTPR) + State-of-the-art SCR VOC and CO removal HYBRID NON-THERMAL PLASMA TECHNOLOGY (EB+MW NTPR) ELECTROSTATIC SEAWATER SCRUBBER, ESWS WASHWATER TREATMENT WWT

14 DEECON retrofit system concept Synergic integration Units developed by VTS and UNINA NTPR ESWS Non Thermal Plasma Reactor Radical oxidation promoted by microwaves and electron beams at low temperatures: NOx conversion to NO 2 NO - 3 salts SO 2 conversion to SO 3 SO - 4 salts VOC conversion to oxodised VOC (Ox-VOC), CO, CO 2 PM oxidation? PM formation? WWT Electrostatic Sea Water Scrabber Improved absorption of sulphur and nitrogen oxides in the more soluble forms of NO 2, SO 3, sulphate or nitrate salts. Oxidised VOC are more soluble than VOCs. Wash Water Treatment

23 Industrial scale ESWS

24 Industrial scale ESWS Thanks to the experience acquired within the DEECON project, VTS and UNINA is working on the design of an industrial ESWS to operate on a 2MW naval engine. Project title: RAIN - Rimozione Avanzata di Inquinanti emessi da motori diesel Navali. Funds requested : 923,521 The unit is under patenting Specifications: Flue gas cooling Flue gas charging Water droplet charging Soluble gas removing Fine particle capture Open or closed loop Industrial ESWS Industrial Droplet Charging Unit
