15 MHI s Long Term 10 t/d CO 2 Capture Demonstration Tests from a Coal Fired Boiler Influence of SOx, NOx & dust in the flue gas (1) SO x The SO x removal efficiency in deep FGD section: =<98% Almost all of the SO x at the outlet of the flue gas cooler was absorbed by the solvent and generated heat-stable salts (HSS) The HSS concentration was maintained at low levels by installing a deep FGD scrubbing section in the bottom of the flue gas cooler (2) NO x Absorption ratio-of NO x Flue gas cooler: almost zero Absorption: 1-3 % The HSS concentration was maintained at low levels (3) DUST An advanced filtration system maintains dust at low levels: =<10mg/kg Influence of dust: no accumulation observed & no flooding or plugging Heat transfer coefficient: No significant decreases were observed in the heat exchanger operated without cooling water 15

16 MHI s Long Term 10 t/d CO 2 Capture Demonstration Tests from a Coal Fired Boiler Conclusion Demonstration operation of ~6,000 hrs was achieved at a commercial coal-fired power station in Japan Behavior and impact of dust, SO x and NO x confirmed Results show that no significant, adverse influences on the process or the equipment were recorded Results indicate that flue gas pre-treatment is important to reduce the level of impurities entering the CO2 Recovery plant In conclusion The MHI CO2 Recovery process can be applied to coal-fired boilers. MHI is working on a next step larger scale demonstration of this process on coal fired flue gas 16
