Trans RINA, Vol 161, Part A4, Intl J Maritime Eng, Oct-Dec 2019 4. CONCLUSIONS
This paper proposes a numerical model to analyze SO2 absorption in seawater. SO2 scrubbers allow employing high-sulphur fuels with a low impact on sulphur emissions. In marine applications, seawater is
a
promising solution due to its availability. This paper proposes a numerical model to analyze SO2 absorption in seawater. A single seawater droplet was analyzed, and the developed model was used to predict the influence of several parameters on the desulphurization efficiency, such
as the droplet diameter, SO2 concentration,
alkalinity and temperature. Several tests were carried out using typical exhaust conditions of marine engines. It was found that a droplet of 200 µm initial diameter can absorb 1.77∙10-14 mol of S for the parameters analyzed, and this reduction improves when the alkalinity and SO2 concentration
temperature and gas
are increased and diameter, seawater temperature are reduced.
Differences up to of 21.5%, 19.8%, 2.2% and 16.3% in the S reduction were obtaining varying the SO2 initial concentration, alkaline initial concentration, initial liquid temperature and initial gas temperature respectively.
