Removal of Particulate Matter (PM) and NOx from marine exhaust gas by combining electrostatic water-spraying scrubber and emulsion oil
In this study, experiments were performed with combination using emulsion oil and an electrostatic water spraying scrubber to evaluate effectiveness for simultaneous removal of NOx 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 NOx emission of up to 28-48% and 18-42%, respectively.
