The Research Institute of Innovative Technology for the Earth (RITE), Kawasaki Heavy Industries Ltd (KHI) and The Kansai Electric Power Co Inc (KEPCO) will install an "energy-saving carbon dioxide separation/collection system" on the premises of KEPCO's Maizuru Power Plant.
They will set up the system as part of the "Project for the Research and Development of CO2 Separation/collection Technologies" of Japan's Ministry of Economy, Trade and Industry (METI) and carry out a practical application test in or after fiscal 2019. This was announced Sept 19, 2017.
Technologies to separate/collect CO2 from exhaust gas emitted at thermal power plants, etc are considered as important technologies for realizing a low-carbon society. However, it has been necessary to reduce the amount of energy consumed at the time of separation/collection.
In the project, the energy-saving CO2 separation/collection system is under development. Thus far, (1) a solid absorbent for CO2 and (2) KCC (Kawasaki CO2 Capture) moving bed system have been developed. By combining them, it becomes possible to separate/collect CO2 by using low-temperature exhaust heat, which is unused energy.
In the practical application test, RITE, KHI and KEPCO will install facilities that can separate/collect about 40t of CO2 per day with the KCC moving bed system using the solid absorbent. The facilities make it easier to realize both a high economic efficiency and a measure against global warming by reducing the (1) energy consumption for CO2 reduction and (2) separation/collection costs, compared with an existing separation technology using amine absorbing liquid.
