Title:
FACILITY AND METHOD FOR THE LIQUEFACTION OF HYDROGEN
Document Type and Number:
WIPO Patent Application WO/2023/280549
Kind Code:
A1
Abstract:
The invention relates to a facility for the liquefaction of hydrogen in a cryogenic liquefied-hydrogen store (8), via a downstream end (22) of a circuit (2) for hydrogen that is to be cooled, the cryogenic store (8) being equipped with a withdrawing pipe (11) configured to allow liquefied hydrogen to be supplied to at least one tank (19) that is to be filled, particularly a mobile tank, the facility (1) comprising a set of heat exchangers (3, 4, 5) in a heat exchange relationship with the circuit (2) for the hydrogen that is to be cooled, and a cooling device in a heat exchange relationship with the set of heat exchangers (3, 4, 5), said cooling device comprising a refrigerator (7) with a cycle-gas refrigeration cycle, the facility (1) comprising at least a first pipe (12) for recovering boil-off gas, comprising a first end intended to be connected to a tank (19) and a second end connected to the downstream end (22) of the circuit (2) for the hydrogen that is to be cooled, said first recovery pipe (12) comprising at least a cryogenic compressor (13) and a portion in a heat exchange relationship with at least a part of the set of heat exchangers (3, 4, 5), the first recovery pipe (12) being configured to recover the boil-off hydrogen, compress it and then cool it and mix it with the liquefied hydrogen at the downstream end (22) of the hydrogen circuit (2).
