Abstract
U ovom radu istražuje se mogućnost uklanjanja SO2 iz dimnih plinova brodskih motora pranjem morskom vodom. Brodski motori kao gorivo uglavnom koriste teško loživo ulje s relativno visokim sadržajem sumpora koji tijekom izgaranja oksidira u SO2, reaktivan i korozivan plin štetan za okoliš. Prije ispuštanja dimnih plinova u okoliš potrebno ga je ukloniti, kako bi se zadovoljili sve stroži međunarodni propisi o zaštiti zraka. Jedna od najekonomičnijih metoda uklanjanja SO2 je skrubiranje morskom vodom, koja se može koristiti kao medij za odsumporavanje zbog svog prirodnog alkaliteta. Uz alkalitet, važan parametar jest i salinitet morske vode, koji utječe na ionsku jakost otopine te tako doprinosi većem stupnju uklanjanja. Kako bi se ispitala mogućnost korištenja morske vode za skrubiranje, napravljen je model procesa odsumporavanja u programskom paketu ChemCAD. Simulacija je provedena za morske vode različitih vrijednosti alkaliteta i saliniteta, koje se mogu naći u morima duž svjetskih plovnih putova. Analizom osjetljivosti utvrđeni su parametri i nezavisne varijable procesa za četiri različita sastava morske vode. Proračun je napravljen za protoke dimnog plina od 1000 m3/h, koliki je protok dimnog plina u pilot postrojenju u sklopu brodogradilišta „Viktor Lenac“ i za stvarni protok dimnog plina brodskog motora od 130.000 m3/h.
Abstract (english)
In this work, a study on SO2 removal from marine engine exhaust gas by seawater scrubbing is researched. Marine engines use heavy fuel oil, with high content of sulphur, which is oxidized to SO2 during combustion. SO2 is highly reactive and corrosive gas with harmful effects on the environment. Before exhaust gases are released into the atmosphere, SO2 content must be reduced to comply with more and more stringent environmental protection laws. One of the most cost-effective abatement methods is flue gas desulphurisation by sea water scrubbing. Sea water can be used for desulphurisation due to its natural alkalinity. Besides alkalinity, salinity is an important parameter contributing to process efficiency by increasing ionic strength of sea water. To explore this process, a desulphurisation model was developed in ChemCAD. Simulation study was then performed for different values of alkalinity and salinity, which can be encountered in seas along different shipping routes. Sensitivity study was used to determine process parameters and independent variables for four different sea water compositions. Analysis was made for flue gas flow rate of 1000 m3/h, as encountered in „Viktor Lenac“ test facility, and for real marine engine flue gas flow rate of 130.000 m3/h.
