Abstract: The increase of CO₂ concentration in the atmosphere has prompted world-wide concern since it is considered to be one of the causes of global warming. The Tokyo Electric Power Company, (TEPCO) has undertaken research to solve this problem. For example, TEPCO has installed pilot plants in its thermal power station, and has been conducting research on CO₂ removal from the flue gases by employing the chemical absorption method and the physical adsorption method using actual boiler exhaust gases. In this research, a technical evaluation is being made on the amount of energy consumption required for CO₂ removal and the problems that will emerge as plant facilities are enlarged.

Keywords: global warming; CO2; carbon dioxide; carbon removal; chemical absorption; physical adsorption; pilot plants; thermal power stations; boiler exhaust gases; energy consumption.
