Abstract
The article examines the specifics of operating power plants in special environmental control areas, following the restrictions of the International Maritime Organization introduced in 2020. It focuses on innovative technologies such as the use of low-sulphur fuels, the implementation of SCR technology, the development of new logistical solutions and the use of new fuels. The method for controlling the emission of sulphur oxides into the atmosphere from power plants must be an integrated one, combining primary and secondary measures. Primary activities include purification of fuel from pollutants - improvement of fuel quality (enrichment of feedstock, use of alternative fuels); suppression of formation of harmful substances during combustion by improving fossil fuel combustion processes (by improving furnace designs, technological methods and regime measures, organization of mixture formation and combustion processes, improvement of fuel injection system). Secondary measures include technologies for capturing pollutants from flue gases, including methods designed for coarse and fine flue gas cleaning (flue gas recirculation, catalytic flue gas cleaning, wet methods, dry methods, absorbers for the cleaning of combustion products of sulphur oxides, cyclone-foam apparatus). The solution to the pollution of the World ocean, and in particular the special environmental control zones, by sulphur emissions from diesel engines primarily depends on the development of highly effective technologies to reduce its concentration at the diesel plant outlet.
