Abstract
Emisije štetnih plinova s brodova odnosno iz dvotaktnih motora koji se pokreću prirodnim plinom znatno doprinose koncentracijama štetnih supstanci koji zagađuju zrak. No postoje tehnička sredstva i metode pomoću kojih se emisija ovih kemijskih spojeva u značajnoj mjeri može smanjiti u cilju očuvanja zdravlja kao i životne sredine i kao bi se brodski prijevoz razvijao kao održiviji oblik prijevoza. Pod pojmom štetnih emisija s brodova uglavnom podrazumijevamo sumporne i dušikove okside nesagorene čestice kao i staklenički plinovi. Međutim količina emisija ovisi o tipu goriva pa teško gorivo emitira više zagađajućih materija od lakših derivata nafte. Zbog porasta sve strožijih regulacija koje se tiču tih emisija proizvođači brodskih motora pribjegavaju primjeni novih metoda kao što su primarne ili sekundarne metode poput SCR sustava. Pa ipak cijena je odlučujući faktor u odlučivanju koje će se gorivo i sustav primijeniti u cilju usuglašavanja sa regulacijama emisija. U ovom završnom radu biti će govora o ispušnim brodskim plinovima, o njihovoj kompoziciji i štetnim supstancama koje se tiču tih emisija kao i načini pomoću kojih se problem emisija može riješiti.
Abstract (english)
Emissions of harmful gases from ships or from two-stroke engines powered by natural gas contribute significantly to the concentrations of harmful substances that pollute the air. However, there are technical means and methods by which the emission of these chemical compounds can be significantly reduced in order to preserve health as well as the environment and as ship transport would develop as a more sustainable form of transport. By the term harmful emissions from ships, we mainly mean sulfur and nitrogen oxides, unburned particles, as well as greenhouse gases. However, the amount of emissions depends on the type of fuel, so heavy fuel emits more pollutants than lighter oil derivatives. Due to the increase in ever stricter regulations concerning these emissions, the manufacturers of bros engines are resorting to the application of new methods such as primary or secondary methods such as the SCR system. And yet the price is a decisive factor in deciding which fuel and system will be used in order to comply with emission regulations. In this final paper, we will talk about ship exhaust gases, their composition and harmful substances related to these emissions, as well as the ways in which the problem of emissions can be solved.
