PROBLEM TO BE SOLVED: To enable recovery of hydrogen gas to remain in high pure form, which is extracted when filling a liquefaction hydrogen storage tank on a liquefaction hydrogen transport shipboard or a land with liquefaction hydrogen while enabling the recovery without discharging mixed gas in ambient air, which is produced when purging a peripheral part of a loading arm with inert gas.SOLUTION: A liquefaction hydrogen transfer system (1) between a first tank (2) on the land side and a second tank (3) on the side of a liquefaction hydrogen transport shipboard, the transfer system comprises: first transfer means (4) capable of transferring liquefaction hydrogen between the first tank (2) and the second tank (3) with a loading arm (4a) in between; second transfer means(5) capable of transferring hydrogen gas to the second tank (3) or from the second tank (3) with a loading arm (5a) in between; inert gas supply means (7A and 7B) capable of supplying inert gas to the second tank (3) when the second tank (3) is emptied; and third transfer means(6) capable of transferring mixed gas on the land side by recovering the mixed gas of inert gas supplied from the inert gas supply means (7A and 7B) and hydrogen gas remaining in the second tank (3).SELECTED DRAWING: Figure 1
【課題】ローディングアーム周辺部分を不活性ガスでパージする際に発生する混合ガスを大気中へ放出することなく回収可能にし、液化水素運搬船や陸上の液化水素貯蔵タンクに液化水素を充填する際に抜き取る水素ガスを高純度のまま回収可能にすること。【解決手段】陸側の第1タンク(2)と、液化水素輸送船側の第2タンク(3)との間で液化水素を移送する液化水素移送システム(1)は、第1タンク(2)と第2タンク(3)との間でローディングアーム(4a)を介して液化水素を移送可能な第1移送手段(4)と、第2タンク(3)へ又は第2タンク(3)からローディングアーム(5a)を介して水素ガスを移送可能な第2移送手段(5)と、第2タンク(3)の空載時に不活性ガスを第2タンク(3)に供給可能な不活性ガス供給手段(7A,7B)と、不活性ガス供給手段(7A,7B)から供給された不活性ガスと第2タンク(3)内に残存する水素ガスとの混合ガスを回収して陸側に移送可能な第3移送手段(6)とを備えている。【選択図】図1
