Özet

The environmental and economic performance of a post-combustion solvent-based carbon capture system (CCS) combined with a selective catalytic reduction (SCR) system is investigated on a 48,600 kW engine container ship to meet the International Maritime Organization’s emission reduction strategies through 2050. The proposed system uses aqueous ammonia to mitigate the produced CO2 and NOX emissions onboard a ship. Moreover, the combined system is investigated through a voyage-based case study using an engine room simulator, assuming that CCS and SCR are implemented on the reference ship. During the case study, the referenced container ship sailed from Rotterdam to New York, and the estimations were made by using Netpas Distance 4.0 software program. Results indicate that a total of 3,606.04 ton-CO2 and 92.40 ton-NOX are produced, while 3,345.43 ton-CO2 and 40.67 ton-NOX are captured during the voyage. Furthermore, an economic analysis is carried out after the case study. Findings of the economic analysis are: CAPEX of CCS is $32.07 MM and SCR is $2.19 MM, while OPEX of CCS and SCR are $188,873 and $103,681, respectively. In addition, it was calculated that implementing CCS could avoid the CO2 tax cost of $19,472, while the economic value of the CO2 captured was $113,590.
