In Mitsubishi Heavy Industries Group, Mitsubishi Heavy Industries Engineering, Ltd. has a CO2 capture technology that uses a proprietary absorption solvent and has constructed the world's largest-scale CO2 capture plant (about 5,000t/day) in the United States. However, this CO2 capture technology has so far only been applied to flue gas from coal-fired power generation and flue gas generated in chemical plants. To respond to the recent social needs for the reduction of CO2 emissions, MHI has commenced with applications of this technology to flue gas in the industrial sector to which it has yet to have been applied. Our case studies so far and future efforts are introduced in this report.
