Harmful emissions into the atmosphere, such as carbon dioxide (CO2), are increasing due to the extremely use of fossil fuels in the world. The shipping also increases global CO2 emissions. This results in critical ecological issues like global warming, climate change and air pollution. Therefore, applications to reduce CO2 emissions are needed, and carbon capture is one of these. In this study, the effects of mono-ethanolamine (MEA), piperazine (PZ) and ammonia (NH3) solvents on the carbon capture costs and CO2 capture rates (%) of the carbon capture system aboard a tanker were investigated for 30 wt% solvents. Capturing performance and economic analyses of the carbon capture system aboard the 49. 990 DWT tanker were performed using Aspen HYSYS software. For different solvents, annual captured CO2 emission amounts and CO2 capture rates (%) were obtained at 85% engine load-cruise mode. For the same geometries of carbon capture columns, the carbon capture costs of the system per ton of CO2 are 82. 6, 69. 6, and 47. 3 for MEA, PZ and NH3 solvents, respectively and the CO2 capture rates are 30. 9%, 36. 7%, and 54% for MEA, PZ and NH3 solvents, respectively. Cost-effective capture of CO2 emissions released from ships into the atmosphere is important for the widespread use of carbon capture and storage systems.
