る。Although it is considered that a method of reducing carbon dioxide in the atmosphere is extremely difficult in practice, some methods for treating carbon dioxide emitted from a certain place such as combustion gas have been proposed. Have been. One method is to fix the separated and concentrated carbon dioxide gas in the form of a clathrate, and finally put it on the deep sea floor to fix it semipermanently.

However, it was very difficult to measure the amount of generated carbon dioxide clathrate for the following reasons.

ある。Since the carbon dioxide clathrate can be generated and existing in the reaction vessel only at a low temperature and a high pressure (for example, 5 ° C., 22 atm or more), it is difficult to handle the carbon dioxide clathrate, and the amount of carbon dioxide clathrate generated is measured. The method has not been established. That is, when the carbon dioxide clathrate is taken out from the reaction vessel into the atmosphere, the carbon dioxide clathrate is easily decomposed, so that handling in the atmosphere is not easy.

Conventionally, the amount of generated carbon dioxide clathrate has been determined by detecting the change in the electric conductivity of the solution in the pressure-resistant reaction vessel as follows. That is, the test water and carbon dioxide gas are put into the reaction vessel 1, the upper lid 2 is covered, and the reaction vessel 1 is set in the cold water tank 4.

(1) The electric conductivity is the reciprocal of the electric resistance of the aqueous solution between the electrodes, and the measurement principle is applied only to an aqueous solution without a solid. When the carbon dioxide clathrate is generated, the generated liquid contains the carbon dioxide clathrate as a crystalline solid, and the measurement principle is not applied. (2) The device for measuring the electric conductivity of only the aqueous solution containing no solid is not considered, and the carbon dioxide gas clathrate cannot be quantitatively determined.

きる。Here, from the reaction formula (1), the carbon dioxide gas clathrate crystal can be formed in an aqueous solution in which salts are dissolved without involving the salts. When formed and grown, the salt concentration of the aqueous solution increases. That is, the amount of water in the aqueous solution is W 1 g, the amount of CO 2 is Gg, the salts are Sg, and the temperature,
It is assumed that the pressure is set and a carbon dioxide clathrate is generated. When the total amount of CO 2 becomes the clathrate, G / 44 ×
(5 + 3/4) × 18 = 2.35 G (g) of water is consumed for the generation of carbon dioxide clathrate crystals, and the remaining water is (W 1 -2.35 G) (g). On the other hand, salts remain in water, so that their concentration increases. For example, if the initial concentration is S / W 1 , the salt concentration at the time of clathrate generation is S / (W 1 -2.35 G). Therefore, the salt concentration a 1 at the initial stage and the salt concentration a at the time of clathrate generation by measuring 2 can be calculated clathrate production amount W 2 from the following equation.
【００１５】 Ｗ2 ＝Ｇ／４４×｛４４＋（５＋３／４）×１８｝＝３．３５×Ｇ こゝで、ａ1 ＝Ｓ／Ｗ1 、ａ2 ＝Ｓ／（Ｗ1 −２．３５

できる。As described above, when the carbon dioxide clathrate is formed, the salts do not enter the carbon dioxide clathrate hydrate, so that the salt concentration increases, and further, the property that the salt concentration is proportional to the electric conductivity of the solution. The amount of carbon dioxide clathrate produced can be calculated quantitatively from the measurement of the electrical conductivity of a solution in which the crystal solid of the clathrate is taken in through a filter.

必要がある。However, when the generated carbon dioxide clathrate is decomposed before passing through the filter, the equation (1) proceeds from right to left and the amount of water increases. As a result, the electric conductivity of the solution becomes smaller, and the amount of carbon dioxide clathrate is also measured to be smaller. Therefore, it is necessary to set the temperature and pressure conditions from the reaction vessel to the filter so that the carbon dioxide clathrate does not decompose.
