This month we present a paper co-authored by Marcin Stec, Adam Tatarczuk, Tomasz Iluk and Mateusz Szul from Institute for Chemical Processing of Coal.
The paper entitled „Reducing the energy efficiency design index for ships through a post-combustion carbon capture proces” was published in International Journal of Greenhouse Gas Control.
This paper discusses the possibility to reduce the energy efficiency design index for ships through a post-combustion carbon capture process. The post-combustion carbon capture process, successfully implemented in the electricity generation sector, allows reduction of CO2 emissions of existing units using fossil fuels with relative simplicity. An assessment of implementing an amine-based carbon capture system onboard of the ship is presented. The analysis covers the energy requirements of the entire system including SO2 removal, carbon capture and CO2 compression. Simulations, conducted for different ambient conditions, revealed that the highest CO2 emission, translating into a reduction of the EEDI, is possible in tropical conditions. The energy efficiency reduction is possible also in arctic conditions to a lesser extent. The post-combustion carbon capture process seems to be a promising technology as the method to reduce the EEDI for ships. An additional advantage is the possibility to retrofit existing constructions as the implementation requires no significant changes in the ship propulsion system. Finally, the nature of the amine-based carbon capture process, aimed to remove acidic exhaust gas components, supports SO2 emission reduction, making the exhaust gas practically sulfur-free.
