  • Publication number: 20250207851
    Abstract: The invention relates to a method for cooling hydrogen, in which method liquefied natural gas is heated by indirect heat exchange in a first heat exchanger with an intermediate fluid flow, the intermediate fluid flow is cooled, a hydrogen gas flow is cooled in a second heat exchanger without being condensed, and a gas flow derived from the cooled intermediate fluid is heated in a second heat exchanger to a temperature of between ?150° C. and ?90° C., which gas flow is withdrawn from the second heat exchanger at said temperature and compressed in a compressor with an inlet temperature of between ?150° C. and ?90° C.

  • Publication number: 20240410649
    Abstract: The invention relates to an installation for producing liquefied gas comprising a circuit for supplying feed gas, a set of heat exchangers, a refrigerator for cooling some or all of the set of heat exchangers, the supply circuit comprising, between the set of heat exchangers and the downstream end thereof, a final expansion turbine for expanding the feed gas in liquid state, the supply circuit comprising a bypass line of the final expansion turbine fitted with a first expansion valve, a second expansion valve disposed in series upstream or downstream of the first expansion valve and of the final expansion turbine, an additional heat exchange line designed to exchange heat with a heat exchanger of the set of heat exchangers when the feed gas is expanded by the first expansion valve via the bypass line, the additional heat exchange line carrying out this heat exchange with said heat exchanger between the expansion carried out by the first expansion valve and the expansion carried out by the second expansion val

  • Publication number: 20240401876
    Abstract: A hydrogen boil-off gas recovery method, comprises liquefying hydrogen by cooling a hydrogen feed stream in a first cryogenic cold box, further cooling the hydrogen in a second cryogenic cold box, liquefying the hydrogen in the second cryogenic cold box or downstream thereof, providing liquefied hydrogen a loading bay containing at least one hydrogen transport truck, sending boil-off gas from at least one hydrogen transport truck in the loading bay to which liquefied hydrogen has been provided to an indirect heat exchanger outside the first and second cryogenic cold boxes in order to warm the boil-off gas and mixing at least part of the warmed boil-off gas with the hydrogen feed stream upstream of the first cryogenic cold box or with hydrogen in a hydrogen refrigeration cycle used to provide refrigeration for the second cryogenic cold box as a function of the pressure of the boil-off gas.

  • Publication number: 20240255219
    Abstract: In a process for cooling hydrogen by means of a refrigeration cycle, a cycle fluid (4), which is nitrogen, is cooled to a temperature lower than ?100° C., at least one portion (8-1) of the cooled cycle fluid is expanded in a turbine (T1) in order to cool the at least one portion of the cycle fluid, which produces a two-phase fluid (6) at the outlet of the turbine, the two-phase fluid is separated in a phase separator (V1), and at least one portion of the gas (8) produced in the phase separator is sent to a first heat exchanger (E1) in order to exchange heat indirectly with the feed gas (1) to be cooled, which produces a cooled feed gas (2) and a heated cycle gas (9), which is compressed in a compressor (C1) and then cooled in a cycle.

  • Publication number: 20230096282
    Abstract: A method for recovering boil-off gas from a system including one or more liquefaction trains including transport trucks or loading bays, a gaseous hydrogen feed stream, a lower-temperature cold box, and a low-pressure hydrogen compressor. The method including collecting a boil-off gas stream from the transport trucks or loading bays, determining the pressure of the boil-off gas stream, and depending on the pressure, recycling the boo-off gas stream to predetermined destinations. Wherein the boil-off gas stream has either a low-pressure, having a pressure of less than 2 bara, or a medium-pressure, having a pressure equal to or greater than 2 bara.
