す。 [Industrial Application Field] The present invention relates to a method for reliquefying generated gas in a low-temperature liquefied gas storage facility. [Prior Art] In low-temperature liquefied gas storage equipment, in order to liquefy and recover the gas that is generated in large quantities especially when receiving low-temperature liquefied gas, the generated gas is generally compressed, and then cooled using seawater or the like. Although it is attempted to re-liquefy it by condensing it and return it to a tank or the like, there is a problem in that the equipment for the re-liquefaction is very large-scale. Furthermore, when shipping low-temperature liquefied gas at room temperature in a low-temperature liquefied gas storage facility, the low-temperature liquefied gas is heated to room temperature using seawater, etc., but with this heating method, the cold heat of the low-temperature liquefied gas is It was simply wasted away in seawater. [Problems to be Solved by the Invention] For this reason, it is conceivable to use the cold energy that is wasted during normal-temperature shipping for cooling for re-liquefying the generated gas. Since the low-temperature liquefied gas is not received simultaneously, it has been difficult to effectively utilize the cold energy of the low-temperature liquefied gas for room-temperature shipping. [Means for Solving the Problems] The present invention has been made in view of these points. When shipping the room temperature liquefied gas, the low temperature liquefied gas for room temperature shipping is used to accommodate metals that produce metal hydrides and to produce metal hydrides. Heat is exchanged by guiding the necessary hydrogen gas through a flow path into a container that can supply it, and the reaction heat generated when metal hydride is generated is cooled by the cold heat of the low-temperature liquefied gas for normal-temperature shipping. After promoting the exothermic reaction, by blocking the outflow of the hydrogen gas, the cold heat of the low-temperature liquefied gas for normal temperature shipping is recovered and stored, and the generated gas that requires re-liquefaction from the low-temperature liquefied gas storage equipment is The generated gas is cooled and reliquefied by introducing it into the container and exchanging heat with the metal hydride, causing the metal hydride to decompose and undergo an endothermic reaction, and causing the generated hydrogen gas to flow out of the container. This method makes it possible to effectively utilize the cold energy of low-temperature liquefied gas for normal-temperature shipping, secure sufficient cold energy for reliquefying the generated gas, and significantly simplify the equipment used in implementation. . [Operation] After storing the cold energy by accelerating the production of metal hydrides using the cold energy of the low-temperature liquefied gas for normal temperature shipping, the generated gas that requires reliquefaction is cooled and reliquefied using the stored cold energy. [Examples] Examples of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of an apparatus for carrying out the present invention, in which two regenerators 1 and 2 are provided.
A flow path 5 is provided in which the flow is switched and circulated,
The other regenerator 2 is provided with a medium flow path 7 for circulating a normal temperature medium 6 such as seawater. Furthermore, the regenerator 1 is charged with metal hydride A having equilibrium characteristics as shown by curve a in FIG. 2, and the regenerator 2 is charged with metal hydride B having equilibrium characteristics as shown by curve b. The regenerators 1 and 2 are connected to each other by a hydrogen gas passage 9 equipped with a valve 8. The metal hydrides A and B exhibit the following reaction.

As shown in Fig. 3, the low temperature liquefied gas 3 for normal temperature shipping is
At the same time, a normal temperature medium 6 such as seawater is passed through the medium flow path 7 of the regenerator 2. Then, in the regenerator 1, the reaction [Me]+[H]-Q→[MeH] takes place, and in the regenerator 2, the reaction [MeH]+Q→[Me]+[H] takes place. That is, the regenerator 1 requires [H], and the regenerator 2 generates [H] through decomposition, and the regenerator 1 requires [H].
Since the pressure is higher in case 2, [H] flows in the direction of the arrow in the hydrogen gas flow path 9, and therefore, in the regenerator 2, it receives heat Q from the normal temperature medium 6, and the [H] also flows in the direction of the arrow. Smooth outflow occurs to promote the decomposition reaction, and in the regenerator 1, the introduced [H] and the reaction heat Q of the exothermic reaction are removed by the low-temperature liquefied gas, so that metallic hydrogen is The formation of chemical compounds is promoted and cold energy is stored. At this time, the low temperature liquefied gas 3 is heated and shipped at room temperature. With the cold heat stored, the valve 8 is closed to block the movement of [H] in the hydrogen gas flow path 9, thereby retaining the cold heat. Next, in order to cool and reliquefy the generated gas using the cold heat of the regenerator 1, the state shown in FIG. 3 is switched to flow the generated gas 4 through the flow path 5 as shown in FIG. Open valve 8. Then, in regenerator 1, the reaction of [MeH] + Q → [Me] + [H] is
In addition, in regenerator 2, [Me] + [H] - Q →
[MeH] reaction will take place. That is, the metal hydride in the regenerator 1 receives heat Q from the generated gas 4 and decomposes to generate [H], and the regenerator 2 requires [H], and Since the pressure is higher in the hydrogen gas flow path 9, [H] flows in the direction of the arrow,
Therefore, in the regenerator 1, the heat Q is received from the generated gas 4, and [H] flows out smoothly to promote the decomposition reaction, and in the regenerator 2, the introduced [H] and the The reaction heat Q in the exothermic reaction is removed by the normal temperature medium 6, thereby promoting the production of metal hydrides. At this time, the generated gas 4 is condensed and reliquefied by cooling. As a result of the above, the reliquefaction temperature of the generated gas can be maintained at a low temperature regardless of the season, and since the amount of cooling energy of the shipped liquid is generally small compared to the amount of heat required to reliquefy the generated gas in the storage facility, reliquefaction is possible. It is possible to secure the necessary cooling and heat. In the above embodiment, the recovery and storage of cold energy and the condensation and reliquefaction of the generated gas are performed by switching the flow path 5, but as shown in FIG. By providing the flow path 5, the switching operation as described above can be eliminated, and furthermore, even when it is necessary to simultaneously ship the room-temperature liquefied gas and condense and re-liquefy the generated gas by receiving the low-temperature liquefied gas. It can be made to work. Moreover, any metal hydride can be selected from the standpoint of its equilibrium characteristics, and various other changes can be made without departing from the gist of the present invention. [Effects of the Invention] According to the above-described method for reliquefying generated gas in the low-temperature liquefied gas storage equipment of the present invention, the cold energy of the low-temperature liquefied gas for room-temperature shipping is recovered and stored by the metal hydride production reaction, and the Since the generated gas is condensed and re-liquefied through the decomposition reaction of the metal hydride, the cold heat of the low-temperature liquefied gas for room-temperature shipping is used to effectively re-liquefy the generated gas and solve the simultaneity problem. It is possible to achieve excellent effects such as being able to be implemented at low cost with simple equipment and a relatively small installation area.
