The project is aimed at innovative abatement systems for the reduction of air pollutants emitted in the exhaust gases of ships’ engines, in particular in the Motorways of the Sea (coastal and port approach areas traded by ro-ro vessels).
The activities involve both simulation of the process for remedial actions and the experimental test of innovative catalytic technologies for marine use. Furthemore, starting from an analysis of direct and indirect effects of gaseous emissions, advanced sensors based on selected bio-monitors are tested and compared with conventional ones. In addition, the project deals with technologies to control and optimize the integrated abatement of the main pollutants (SOx, NOx and PM, particulate and smoke), to be implemented with selective catalytic processes. To this purpose, models are developed to enable optimal control strategies for the catalytic system.

new solutions for marine applications
All these aims are motivated by the urgent need for new solutions for marine applications, more and more subject to regulations stimulated by environmental protection criteria. In fact, at present, only shipborne systems for the reduction of a single pollutant are available on the market but ship owners seldom install them aboard. The project aims at identifying design specifications for a compact integrated selective catalytic reduction (SCR) system, for the concurrent abatement of all three considered kinds of pollutants, with a special attention on efficiency, size, investment and operating costs. Equally important is the problem of controlling the catalyzer efficiently, in terms of operation and regeneration, and optimizing its parameters in terms of expected performance and encumbrance.

ISSIA MAIN ACTIVITIES
The main activities of ISSIA are:
- Coordination: ISSIA-CNR had the role of Coordinator for the activities of the Partners of the entire project.
- Development of control and optimization techniques for integrated abatement systems. Suitable methodologies have been developed, aimed at the optimization of structural parameters and the efficient control of the complex and integrated systems for the abatement of ship pollutant emissions studied in the ECOMOS Project.
In particular, techniques have been developed that, exploiting a numerical model of a catalytic plant, allow to pursue the following aims:
- to implement real-time optimal control strategies that maximize the abatement efficiency depending on the conditions of the gas entering the catalyst, on the basis of suitable requisites (e.g., to keep the gas output temperature within a desired range of values);
- to optimize, in the design phase, some structural parameters of the catalytic abatement system, e.g., to reduce the encumbrance without penalizing the efficiency.
