Performance Assessment of an Exhaust Gas CO2 Absorption (EGCA) System Installed on a 1.075-MW HiMSEN 5H22CDF Engine.

• Exhaust gas CO 2 absorption (EGCA) system was installed on MW-scale marine engine. • EGCA performance was certified as per the test procedure described in NTC 2008. • 29/30 wt%(E2/E3 mode) of CO 2 absorption was obtained by EGCA system. • Pretreatment reactor needs to be combined for stable operation of EGCA system. The management of CO 2 emissions from fossil fuel-powered ships has been considered for complying with future enhancements in CO 2 emission regulations in the shipbuilding industry. These regulations are (or will be) enforced using indexes such as the energy efficiency design index, energy efficiency existing index, energy efficiency operational indicator, and carbon intensity indicator. Hence, developing technology for reducing CO 2 emissions from ships is necessary. This paper reports on the CO 2 absorption performance of a pilot-scale CO 2 capture system installed on a 1.075-MW HiMSEN 5H22CDF engine. The proposed technology is an exhaust gas CO 2 absorption (EGCA) system. Our CO 2 capture system is based on an exhaust gas cleaning system, which is already commercialized to reduce SO x emissions from ships that use heavy fuel oil. The CO 2 absorption performance of the EGCA system was evaluated following the test procedure described in the NO x Technical Code 2008 (NTC 2008). Under the certified test procedure described in NTC 2008, the EGCA system exhibited 29/30 wt% (E2/E3 test mode) of CO 2 absorption. On the basis of the test results, we expect that ships will be able to comply with future CO 2 emission regulations by using the proposed EGCA system. [ABSTRACT FROM AUTHOR]
