Special Issue Information

Dear Colleagues,

International Maritime Organization proposed a new preliminary strategy for reducing greenhouse gas emissions from ships in 2018, and the global ship pollutant emission regulations will also be comprehensive, meticulous, and strict. At present, the global shipping industry is facing the dual pressure of ship exhaust pollution control and greenhouse gas emission reduction, with green shipping and efficient transportation having become the direction of development. Likely to continue in the future, the challenges facing the shipping industry include determining how to cope with the continuous upgrading of the pollutant emission regulations for marine engines, how to efficiently and economically achieve near-zero emissions of various pollutants of marine engines, and how to truly achieve green shipping, safe operation, and efficient transportation. As far as the development is concerned, the use of low-carbon and zero-carbon fuels has become one of the most effective ways to solve the problem of ship greenhouse gas emission reduction. In spite of this, the change of engine fuel type leads to the change of pollutant emission characteristics, and the upgrading of environmental protection regulations also leads to the continuous increase of pollutant limits. It is urgent to realize the near-zero emission of various pollutants from marine engines.

This Special Issue is a follow-up of the first Special Issue entitled “Shipping Emissions and Air Pollution” (https://www.mdpi.com/journal/atmosphere/special_issues/Shipping_Emission_Air_Pollution), and will cover all aspects of shipping-related air pollution issues. We invite the participation of scholars in related fields.

This paper introduces a numerical model dedicated to simulating SO2 adsorption during the dynamic interplay between combustion gases and water droplets. The research delves into essential chemical–physical parameters governing mass transfer in these interphase interactions. The proposed simplified model provides preliminary results regarding the granulometric curve of sprays, particularly focusing on the minimal droplet size crucial for effective wet scrubber operation. Our findings underscore a critical diameter below which the spray loses its efficacy under varied boundary conditions. Notably, a single droplet with a maximum diameter of 2 mm absorbs more SO2 than smaller counterparts, peaking at 4.36 × 10−5 g of SO2 within the simulation timeframe. Furthermore, the study explores a specific water mass, revealing that smaller droplets, such as 1 mm, significantly optimize the absorption process. These droplets achieve a SO2 absorption quantity over 5.77 times greater than that of a 2 mm droplet. This research serves as an initial tool for optimizing droplet distribution in sprays, thereby enhancing capture efficiency. The insights presented here offer valuable guidance for designing efficient wet scrubber systems, crucial for pollution control in industrial and environmental applications. Full article
