Abstract

PURPOSE:To obtain liquid hydrogen with a low cost by a method wherein the cold heat of LNG is utilized for the precooling heat source of the operating fluid of the gas of He or H2 to generate cold heat for cooling hydrogen while a low-temperature gas compressor is utilized for the boosting of the operating fluid of He or H2 gas, returned from a low temperature unit. CONSTITUTION:A liquid hydrogen manufacturing device, operated by SIMPLELINDE method, is constituted of a material hydrogen line 1, a counterflow type heat exchanger 2, an LNG line 3, a recycle H2 line 4, and a low-temperature compressor 5 attached to the recycle H2 line 4 while material H2 and recycle H2 as a cold heat source are precooled by the cold heat of LNG and arrives at a J-T valve (Joule-Thomson valve) 6. Further, said device is also provided with a heat exchanger 7 and a LH2 tank 8. The cold heat of LNG is utilized for the cold heat source for precooling and the low- temperature gas compressor is utilized for the generation of high-pressure gas. As a result, the charges of power and electric power can be reduced remarkably.
