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.

きな要因であると推論されている。The concentration of carbon dioxide in the atmosphere is 315 ppm in 1960 and 325 pp in 1970.
m, 1980: gradually increased to 335 ppm, and is currently said to be about 350 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. Since the aging trend of gas concentration is similar,
It has been speculated that carbon dioxide emissions from fossil fuel combustion are a major factor in the rise in atmospheric concentrations.

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.

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 combustion exhaust gas of fossil fuel 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 clathrate hydrate). This clathrate hydrate is stable without separation under deep sea environment conditions, and does not float because its specific gravity is larger than that of seawater.

クラスレート水和物の分解の可能性がある。However, it has been confirmed that heat of reaction (approximately 100 kcal / kg) is generated in this precipitation-forming reaction, and in the treatment of a large amount of carbon dioxide gas, the ecological environment is destroyed due to an increase in the temperature of seawater due to the reaction, and the surrounding environment is further reduced. There is a possibility that clathrate hydrate may be decomposed due to an increase in temperature.
