Title:
HYDROGEN LIQUEFACTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/272971
Kind Code:
A1
Abstract:
A hydrogen liquefaction system, wherein a room-temperature compressor unit (1) outputs a high-pressure hydrogen gas to a hydrogen liquefaction unit (200) by means of a high-pressure gas pipeline (7); liquid hydrogen cooled and liquefied in the hydrogen liquefaction unit (200) is output to a first inlet of a liquid hydrogen low-temperature container (36); a 20K saturated hydrogen gas flows out from the first outlet of the liquid hydrogen low-temperature container (36), and is sequentially transported to a third outlet of the hydrogen liquefaction unit (200) and a low-pressure inlet of the room-temperature compressor unit (1) by means of a low-pressure gas pipeline (9); a second outlet of the hydrogen liquefaction unit (200) is connected to a middle-pressure inlet of the room-temperature compressor unit (1) by means of a middle-pressure gas pipeline (8); and a raw material hydrogen gas also flows into the hydrogen liquefaction unit (200), is then cooled to the liquid hydrogen, and flows into the liquid hydrogen low-temperature container (36) from a fourth outlet of the hydrogen liquefaction unit (200).
