25th ETH Nanoparticles Conference (NPC) 2022

The 25th ETH Nanoparticles Conference (NPC) took place from 21. to 23. of June 2022.

In a presentation titled “Evaluation of aerosol emissions from a marine diesel engine using a wet sulfur scrubber and filtration system for exhaust gags abatement”, Dr. Seongho Jeong provided an analysis of the physical and chemical properties of particles derived from various marine fuels. These emissions underwent treatment by abatement systems, enabling the utilization of high sulfur-containing fuels.

The study shed light on the effectiveness of particle removal by wet scrubbers, highlighting that their efficiency may not be as significant as initially anticipated. This finding underscores the necessity for additional abatement systems onboard vessels to ensure a remarkable reduction in particle emissions. Among other proposed solutions, the combination of a wet-electrostatic precipitator emerged as a promising approach.

His research demonstrated that this combination resulted in a substantial decrease in both gaseous and particulate emission, offering an innovative solution to effectively address the challenges associated with aerosol emissions from marine diesel engines.






The ETH Nanoparticles Conference (NPC) serves as an interdisciplinary platform for expert discussions on all aspects of nanoparticles, freshly emitted from various sources, transformed in ambient air, distributed on local and global scale, on technical mitigation aspects, particle legislation, and impact of particles on health, environment, and climate. At the conference the researchers could network with other scientists and representatives from industry and legislation.
