Facility and method for hydrogen refrigeration, comprising a hydrogen circuit to be cooled, comprising:—a first and a second set of heat exchanger(s) arranged in series for exchanging heat with the hydrogen circuit to be cooled;—a first cooling device for exchanging heat with the first set of heat exchanger(s) comprising a refrigerator that operates a refrigeration cycle of a first cycle gas;—a second cooling device for exchanging heat with the second set of heat exchanger(s) comprising a refrigerator that operates a refrigeration cycle of a second cycle gas having a molar mass of less than 3 g/mol, the refrigerator of the second cooling device comprising, arranged in series in a cycle circuit: at least one centrifugal compressor, a cooling member, an expansion member and a member for reheating the second expanded cycle gas;—a system for mixing at least one additional component having a molar mass greater than 50 g/mol with the second cycle gas before it enters the at least one centrifugal compressor and a member for purifying the mixture at the outlet of the at least one compressor configured to remove the at least one additional component up to a determined residual content and located upstream of the first set of heat exchanger(s).

A heat exchanger having a first and second mixing devices having at least one lateral channel configured in order for a first phase of the first fluid to flow from at least one first inlet; a series of longitudinal channels extending in the longitudinal direction and each configured in order for a second phase of the first fluid to flow from a second inlet to a second outlet, the longitudinal channels succeeding each other in a lateral direction orthogonal to the longitudinal direction; and at least one opening fluidly connecting the at least one lateral channel to at least one longitudinal channel such that the first and second mixing devices are configured to distribute a mixture of the first phase and the second phase via the second outlets of their respective longitudinal channels.

Plant and process for the production of liquid methane from a feed gas stream comprising at least methane and carbon dioxide. A feed gas stream is injected into a COcrystallizer in countercurrent fashion against a stream of predominantly liquid methane, thereby crystallizing amounts of carbon dioxide from the feed gas stream. Gaseous methane recovered from the COcrystallizer is liquefied at a liquefaction exchanger.
