を特徴とするCO2の固定化法である。The present invention is a fresh or sea water is fed mixed with CO 2 in the pipeline boosted and cooled to guide the pipeline into the sea of CO 2 hydrate product satisfying temperature to produce a CO 2 hydrate for the pressure a method for immobilizing CO 2, characterized in that CO 2 hydrate will be released into the seawater in the conditions of stable pressure and temperature.
第１表はCO2ハイドレイトの生成する水深と温度との関
係を示したものである。水深が深ければ圧力が高いの
で、それに対応する水温は高くてもCO2ハイドレイトを
生成することができる。Table 1 shows the relationship between the depth of water produced by CO 2 hydrate and the temperature. The deeper the water is, the higher the pressure is, and therefore the CO 2 hydrate can be generated even if the corresponding water temperature is high.
次に、CO2ハイドレイトおよび海水の比重について説明

全かつ安定的にCO2を固定することができる。The specific gravity of CO 2 hydrate is about 1.129, and it is known that it is hardly affected by temperature and pressure. Also, the specific gravity of seawater at atmospheric pressure is about 1.03, and even if the water depth increases and the pressure increases, the increase in specific gravity of seawater is small,
It can be ignored for the specific gravity of CO 2 hydrate. If the CO 2 hydrate thus generated is left in seawater or freshwater, it will sink naturally, and if it is an ocean, it will be deposited on the seabed and CO 2 can be fixed safely and stably.

イトを生成させて海水中に放出させる。Boosting the CO 2, at a pressure and temperature conditions are satisfied under the CO 2 is CO 2 hydrate is produced, but it is to produce an CO 2 hydrate by mixing with seawater or freshwater, CO 2 Hydrate solid CO 2 inside the pipeline
When it solidifies in a hydrate and makes it difficult to transport it after that, supply the seawater or freshwater to the CO 2 pipeline with a margin to generate the CO 2 hydrate and excess seawater or freshwater. And may be mixed (slurry) to facilitate transportation in the pipeline. Also, when CO 2 hydrate is generated, the heat of formation that is generated when CO 2 hydrate is generated (per 1 kg of CO 2 hydrate)
(80kcal) is radiated through a pipeline to generate CO 2 hydrate and release it into seawater.

Depending on the sea area, 200 to 500 in the sea near Japan
In the sea deeper than m, CO 2 hydrate satisfies the stable pressure and temperature conditions.

の間次第に低温になる海水により間接冷却される。An embodiment of the present invention will be described with reference to FIG. For example, CO 2 recovered from the combustion exhaust gas is pressurized by the compressor 1, cooled by the cooler 2 and condensed by the dehydrator 3 to remove water associated with CO 2 . CO 2 from which water has been removed is CO 2
The seawater is transported from the pipeline 4 toward the seabed, and is indirectly cooled by the seawater whose temperature gradually decreases during that time.
一方、水ポンプ７で加圧された水も、CO2パイプライン
４に沿って敷設された水パイプライン５より、その周囲
の海水により冷却されながら輸送される。On the other hand, the water pressurized by the water pump 7 is also transported from the water pipeline 5 laid along the CO 2 pipeline 4 while being cooled by the seawater around it.

するので、水の供給位置には制限がない。Even if CO 2 or water (fresh water, seawater) is mixed at a position before reaching a predetermined temperature, it will be cooled by the seawater around the CO 2 pipeline 4 to reach a predetermined temperature during transportation in a mixed state. Since CO 2 hydrate will start to be generated at that point, there are no restrictions on the water supply position.

Although but there is a possibility that the closed, if Motasere sufficient margin in the supply amount of water, CO 2 Hydrate After completion of generation CO 2
The mixed state of hydrate and water, that is, the state of CO 2 hydrate slurry, results in the prevention of blockage of the CO 2 pipeline 4.

する。The seawater pressure around the CO 2 hydrate producing area of the CO 2 pipeline 4 may be small, but the CO 2 hydrate production is sufficient and the CO 2 hydrate (or CO 2 hydrate slurry) is transferred to the CO 2 pipe. At the time of discharging from the line 4, it is necessary to satisfy the pressure and temperature for the CO 2 hydrate to be stable. The CO 2 pipeline 4 is guided to the sea area under such conditions, and CO 2 hydrate (or CO 2 hydrate slurry) is released. The released CO 2 hydrate has a larger specific gravity than seawater, so it sinks and accumulates on the seabed.
次に、本発明の実施例の具体的な数値例を示す。Next, specific numerical examples of the embodiment of the present invention will be shown.
CO2ハイドレイトは50ata、10.3℃で水（淡水）と混合さ

域でも十分CO2ハイドレイトを生成することができる。CO 2 hydrate is mixed with water (fresh water) at 50ata and 10.3 ℃ to produce CO 2 hydrate. If the pressure of the compressor 1 is appropriately selected, sufficient CO 2 hydrate can be generated even in a region where the depth is 500 m and the seawater temperature is 2 ° C.

とも可能である。For CO 2 transported to this depth of 500m and seawater temperature of 2 ℃,
Fresh water that has been cooled and transported by the surrounding seawater via the water pipeline 5 is added by the water pump 9 on the ground, and CO 2 is added.
Convert to hydrate. The addition of water is not limited to this, and it is also possible to install a seawater pump 9'at an appropriate position in the sea and supply cold seawater around the pump 9'to the liquefied CO 2 .
CO2ハイドレイトはCO2１モルに対して平均7.3モルの水

きることは云うまでもない。CO 2 hydrate is CO 2 1 reacts with an average 7.3 moles of water per mole 1 mole of CO 2 but hydrate is produced, 50a
At ta., CO 2 dissolves in water about 10%. So, for example,
CO 2 hydrate 50 tons / hour, water 50 tons / hour CO 2 hydrate to produce CO 2 hydrate slurry 17.1 tons / hour CO 2
It is necessary to react with 82.9 tons / hour of water. (17.1 tons / CO 2 12.5 ton / time of the CO 2 in the case is the CO 2 hydrate, and the remaining CO 2 is dissolved in water) as described above, CO 2 Hydrate generating heat during generation (1
80 kg / kg of CO 2 hydrate is generated, so CO 2
In order to generate hydrate slurry and release it into the sea, it is necessary to release this heat of formation. This generated heat is released by indirect cooling with seawater through a pipeline, but from the point where seawater was added to the CO 2 pipeline, a 10-inch diameter pipeline with a length of 10.4 km ( An extension of CO 2 pipeline 4) is required. It goes without saying that the pipeline length can be shortened by increasing the pipe diameter.
このようにしてCO2ハイドレイト生成熱を除去されたCO2
ハイドレイトスラリー７は海中に安定して放出され、CO

する。CO 2 which was thus removed of CO 2 hydrate generating heat
The hydrate slurry 7 is stably released into the sea, and CO
2 Hydrate 8 is heavier than the specific gravity of seawater and therefore sinks to the bottom of the sea.
