A study on carbon dioxide emissions reduction in marine diesel engines using a chemical carbon absorber

다국어 초록 (Multilingual Abstract)

The shipping industry is responsible for a considerable portion of global carbon dioxide (CO2) emissions, and reducing these emissions is crucial to mitigate the impacts of climate change. In this study, a chemical carbon absorber (CCA) was used to reduce CO2 emissions from marine diesel engines, and an experiment was performed to determine the efficiency of the method and quantify the reduction achieved. The experiment consisted of injecting 30% and 100% of aqueous CCA into the exhaust gas pipeline via the nozzle of a selective catalytic reduction system. The CO2 concentration in the exhaust gas before and after the CCA injection point was measured to monitor the CO2 emission reduction. The results showed that using CCA can reduce CO2 emissions from the exhaust gas of marine diesel engines. However, further research is needed to optimize the process and improve its efficiency. Three potential areas for future research include installing reductions within the exhaust pipe to increase reaction contact time, recycling waste heat energy from the engine to increase reaction temperature, and improving mixing units to enhance reaction efficiency at higher engine loads. Overall, the results of this study confirm that using CCA technology can reduce CO2 emissions from marine diesel engine.
