Abstract
【解決手段】液体水素製造装置HSは、循環水素を冷媒とする冷凍サイクル部Rと、高圧の原料水素を冷凍サイクル部Rにより冷却しジュールトムソン弁12で断熱膨張させて液体水素を生成する液体水素生成部Pとを備えている。冷凍サイクル部Rと液体水素生成部Pとにわたって、第1、第2熱交換器E1、E2が設けられている。液体水素製造装置HSは、液体水素輸送船16の液体水素貯槽で発生したボイルオフガスを再液化して液体水素を生成するボイルオフガス処理機構を備えている。ボイルオフガスは、非常に低温の循環水素が流れる部位において水素循環通路1に導入され、これにより生じる余剰の循環水素は、循環水素が常温の状態にある部位から原料水素通路11に排出される。
