Methods for reducing pollution of atmosphere with exhaust gases from marine diesel engines

Ekologija i očuvanje ljudskog okoliša jedan su od važnijih segmenata u znanstvenom istraživanju. U samim počecima rješavali su se problemi onečišćenja s kopna, a danas se sve više i zahtjevnije obraća pozornost onečišćenja s brodova. Onečišćenje zraka ozbiljan je problem i za zdravlje ljudi i za ukupni ekosustav. Emisije s brodova uključuju onečišćivače zraka, stakleničke plinove i supstance koje oštećuju ozonski omotač, s posljedicom ugrožavanja ljudskog zdravlja i okoliša, jednako kao i emisije sumpornih oksida (SOx), dušikovih oksida (NOx) i ugljični dioksid (CO2) koji uzrokuju zakiseljavanje. Onečišćenje zrakom ne poznaje državne granice pa je to područje koje zahtijeva međunarodnu suradnju. Zbog donesenih različitih zakona emisije stacionarnih postrojenja su znatno smanjene dok je onečišćenje brodskim emisijama sve veće, pa se radi toga u današnjim vremenima intenzivno krenulo prema potrebama za smanjivanje štetnih emisija sa brodova. Ovaj je problem tako postao primaran, pa se uz međunarodne propise pridružuju i nacionalni propisi radi ograničenja emisija s brodova u pojedinim zemljama, a osobito kod onih koje su izložene brodskim emisijama i prometnijim morskim putovima.Ecology and the preservation of the human environment is one of the most important segments in scientific research. At the beginning of the time, the land pollutions were being solved, today more and more attention is paid to pollution from ship. Pollution of air is a serious problem for human health and all ecosystem. Emissions of the ship include air pollutants, greenhouse gasses, and substance which damage the ozone layer, with the consequence of endangering human health and the environment. Emissions of sulfur oxides (SOx), nitrogen oxides (NOx) and carbon oxides (COx) cause acidification and also adversely affect the environment and human health. Pollution of air does not know the national borders, so this is the area that requires the highest level of international cooperation. Pollutions of stationary plants are significantly reduced because of different passed laws, while is pollution by ship emissions are increasing, and because today the intensive approach is dedicated to the needs to reduce harmful emissions from ships. This problem became primary, so the international and national regulations on emission limits from ships in some countries, have been adopted especially those which are exposed to more emissions from the ship and busy sea routes
