Title:
DEVICE AND METHOD FOR LIQUEFYING A FLUID SUCH AS HYDROGEN AND/OR HELIUM
Document Type and Number:
WIPO Patent Application WO/2022/171485
Kind Code:
A1
Abstract:
Disclosed is a device for liquefying a fluid, comprising a circuit (3) for fluid to be cooled, the device (1) comprising a set of one or more heat exchangers (6, 7, 8, 9, 10, 11, 12, 13) exchanging heat with the circuit (3) of fluid to be cooled, at least one first cooling system (20) exchanging heat with at least some of the set of one or more heat exchangers (6, 7, 8, 9, 10, 11, 12, 13), the first cooling system (20) being a refrigerator with refrigeration cycle of a cycle gas mostly comprising helium, the refrigerator (20) comprising, arranged in series in a cycle circuit (14): a cycle gas compression mechanism (15), at least one cycle gas cooling member (16, 5, 6, 8, 10, 12), a mechanism (17) for expansion of the cycle gas and at least one expanded cycle gas heating member (13, 12, 11, 10, 9, 8, 7, 6, 5), wherein the compression mechanism comprises at least four compression stages (15) in series, consisting of a set of one or more centrifuge-type compressors (15), the compression stages (15) being mounted on shafts (19, 190) rotated by a set of one or more motors (18), the expansion mechanism comprising at least three expansion stages in series, consisting of a set of centripetal turbines (17), the at least one cycle gas cooling member (16, 5, 6, 8, 10, 12) being configured to cool the cycle gas at the outlet of at least one of the turbines (17) and wherein at least one of the turbines (17) is coupled to the same shaft (19) as at least one compression stage (15) so as to supply the compression stage (15) with the mechanical work produced during the expansion.
