ないのが現状である。2. Description of the Related Art Carbon dioxide in flue gas generated by the combustion of fossil fuels, such as power boilers and industrial boilers, has conventionally been released into the atmosphere without treatment. At present, almost no industrial measures have been taken for the purpose of reducing the amount (concentration) of carbon dioxide gas to be discharged from coal.

1980: Slowly increased to 335 ppm, and currently about 350
It is said to be ppm. The cause of the increase in carbon dioxide gas concentration is thought to be the combined result of various factors, including logging, desertification of forests, destruction of coral reefs, and artificial increase. It is inferred that carbon dioxide emissions from fossil fuel combustion are a major factor in the increase in atmospheric concentration because of the similar tendency of increasing gas concentration over time.

気中の炭酸ガス濃度が増加するものと予測できる。[0004] An increase in carbon dioxide in the atmosphere raises the temperature of the atmosphere, leading to warming of the climate or the global greenhouse effect, resulting in melting of Antarctic icebergs, rising seawater temperatures, rising sea levels, forest desertification, and food shortages. And so on, which will endanger human life in the future. If fossil fuels continue to be burned as they are now and the carbon dioxide in the exhaust gas is released as it is, it can be predicted that the concentration of carbon dioxide in the atmosphere will surely increase in the future.

も大きいため浮上することはない。[0005] In order to reduce the phenomenon of increasing carbon dioxide in the atmosphere, all or part of the carbon dioxide contained in the flue gas of fossil fuels is separated and recovered, and the carbon dioxide is pumped to the deep sea. Has been proposed to precipitate and produce a crystalline compound (referred to as carbon dioxide clathrate hydrate). This carbon dioxide clathrate hydrate is stable without separation under deep sea environment conditions, and does not float because it has a higher specific gravity than seawater.
