2. Experimental
Realisation of the current project necessitated the construction
of a pilot plant at the Fincantieri Shipyard, Riva Trigoso, Italy. This
consisted of an Isotta Fraschini V1716T2TE, used as an on-board
auxiliary engine; an oxidation catalyst, assembled on commission
by Opitergina Marmitte di Nespolo Renzo & C (S.N.C.); and a seawater
scrubbing system, obtained from EcoSpray Technologies
S.r.l. The main engine and catalyst characteristics are listed in
Table 1. It should be noted that the catalyst and scrubber were
dimensioned on the basis of a preliminary laboratory investigation
[28] and taking into account the engine emissions and exhaust
flows provided by the manufacturer.
