Demonstration Plant of the Kawasaki CO2 Capture (KCC) System with Solid Sorbent for Coal-Fired Power Station

In a Kawasaki CO2 capture (KCC) system, CO2 in an exhaust gas is captured using a solid sorbent system with low-temperature steam. Because this system reuses the waste heat, it conserves energy in comparison with other conventional technologies. While a moving bed system makes it possible to apply the KCC technology to a large-scale plant, technology development at a large test facility is necessary. Therefore, this study investigates the application of the solid sorbent developed by Research Institute of Innovative Technology for the Earth (RITE) to the KCC moving-bed system for practical use. This study also evaluates the performance of the solid sorbent in a bench-scale test plant and preliminarily examines the installation at a 40 t-CO2/d-scaled pilot test plant to identify technological challenges at coal-fired power stations.
