Experimental Investigation and Mathematical Modeling of the Reaction between SO2(g) and CaCO3(s)-containing Micelles in Lube Oil for Large Two-Stroke Marine Diesel Engines
Abstract
Sulfur dioxide, formed in combustion of sulfur-rich fuels in diesel engines, may oxidize and react with water to form corrosive H<sub>2</sub>SO<sub>4</sub>. However, the SO<sub>2</sub> may also be absorbed in the lube oil and consume CaCO<sub>3</sub>-containing reverse micelles. In this study, the CaCO<sub>3 </sub>+ SO<sub>2</sub> reaction was investigated in a batch reactor setup at temperatures and pressures similar to those on the cylinder liner in an engine. The conversion of CaCO<sub>3</sub> and the formation of products were determined by Fourier Transform Infrared Spectroscopy (FTIR). CaSO3 was the main product, but CaSO<sub>4</sub> was observed at extended residence times and increased temperature. The SO<sub>2</sub>-CaCO<sub>3</sub> reaction exhibited only a small temperature dependence; the increase in the rate constant with temperature was partly off-set because the absorption of SO<sub>2</sub> in the lube oil emulsion decreases at increased temperature. The reaction rate increased slightly with the initial water concentration due to increased SO<sub>2</sub> absorbance. A mathematical model for the batch reactor was set up and kinetic parameters were determined by fitting predictions to the experimental data. The model was then used to predict the CaCO<sub>3</sub> conversion in lube oil from SO<sub>2 </sub>for conditions relevant to a full-scale engine application. Simulations showed that consumption of CaCO<sub>3</sub> from SO<sub>2</sub> is insignificant in a two-stroke marine diesel engine application and that the H<sub>2</sub>SO<sub>4</sub>-CaCO<sub>3</sub> reaction is far more important than the SO<sub>2</sub>-CaCO<sub>3</sub> reaction.
