| Outline of Final Research Achievements |
The aim of this study is to remove PAHs and PM emitted from marine diesel. The experimental system consisted of a plasma process unit, a gas heat exchanger and an electrostatic precipitator.
The amount of fine particles generated in the plasma process unit increased with increasing applied voltage and decreasing the electrode length. This is most likely due to SO2 included in the exhaust gas.
As a result of investigation of the effect of the electrostatic precipitator, dry soot can be remove at the gas temperature of approximately 130 oC. The removal efficiency of sulfate and SOF improved due to decreasing the exhaust gas temperature. Furthermore, it was shown the effect of the gas heat exchanger and the electrostatic precipitator on the removal of PAHs in the exhaust gas.
