Abstract: In this study, experiments were performed with combination using emulsion oil and an electrostatic water spraying scrubber to evaluate effectiveness for simultaneous removal of NO_x and Particulate Matter (PM) emissions in marine exhaust gas. The effects of several parameters, such corona power, gas flow rate, on the contaminant removals have been investigated intensively. Total PM removal efficiency was higher than 99% by electrostatic water spraying scrubber and reduction in NO and NO_x emission of up to 28-48% and 18-42%, respectively.

Keywords: emulsion oil; electrostatic water spraying scrubber; particulate matter; marine exhaust gas; NOx; nitrogen oxides; corona power; gas flow rate; contaminant removal.
