<p>PURPOSE:To effectively liquefy the evaporated gas again by recovering the cold of the low-temperature liquefied gas provided for the normal-temperature shipment, through the formation reaction of metal hydride. CONSTITUTION:The low-temperature liquefied gas 3 provided for normal-temperature shipment is allowed to pass through a flow passage 5, and a normal- temperature medium 6 is allowed to pass through the medium passage 7 of a cold accumulator 2. Then, hydrogen gas flows in the direction of arrow in a passage 9, the decomposition reaction is accelerated in the cold accumulator 2, the reaction heat Q is removed by the low-temperature liquefied gas in a cold accumulator 1, the formation of metal hydride is accelerated, and the cold is accumulated. Then, the path is switched to permit the evaporated gas 4 to flow in the passage 5, and a valve 8 is opened. Then, hydrogen gas flows in the direction of arrow in the passage 9, the decomposition reaction is accelerated in the cold accumulator 1, and the formation of metal hydride is accelerated in the cold accumulator 2. At this time, the evaporated gas 4 is condensed by cooling and liquefied again.</p> |
