As a countermeasure for global warming, the development of CO₂ recovery technology from fossil fuel power plant flue gas has continued. MEA processes are widely used for CO₂ recovery from combustion flue gas in beverage use, etc. However, if we consider power plant scale CO₂ recovery, the biggest theme is the reduction of energy needed to recover CO₂. Our presentation focuses in sterically hindered amines and a new absorber packing. Also, the result of optimum steam system analysis are indicated. CO₂ disposal method is needed with the combination of CO₂ recovery, therefor CO₂ subterranean disposal method is also discussed as the practical way.
