The present disclosure relates to a hydrogen liquefaction system, comprising a hydrogen pipe, where gaseous hydrogen is introduced at a front end, heat exchange occurs in a heat exchange unit leading to liquefaction of gaseous hydrogen into liquid hydrogen; a pre-cooling device formed between the front end of the hydrogen pipe and the first heat exchange unit; an oxygen pipe, where gaseous oxygen is introduced at a front end, heat exchange occurs in the pre-cooling device leading to liquefaction of gaseous oxygen into liquid oxygen; and a heat exchange device, which is in thermal contact with the first heat exchange unit of the hydrogen pipe so as to perform heat exchange with the first heat exchange unit of the hydrogen pipe such that pre-cooled gaseous hydrogen can be liquefied into liquid hydrogen.
摘要:
In a process for the recovery of krypton and xenon, an oxygen-enriched stream containing krypton and/or xenon and hydrocarbons is removed from an air separation unit. A substantial portion of the hydrocarbons, especially methane, ethane, and acetylene, is removed from the oxygen-enriched stream prior to the distillation process. The hydrocarbon removal process includes, but is not restricted to, the hydrocarbons reacting with a portion of the oxygen present in the feed gas. The krypton and xenon are eventually recovered from the oxygen stream through a distillation process. The distillation process is performed in such a manner that at least a stream further enriched in both krypton and xenon is produced.

Provided is a process for purfying a gas. In the process, the gas to be purified flows through a hollow dielectric tube. An electric field in the gas to be purified is created by a traveling electromagnetic wave which travels in the dielectric tube and is suitable for creating, in the gas, an atmospheric-pressure plasma which is not in local thermodynamic equilibrium, for the purpose of dissociating impurities in the gas in order to form reactive compounds. The formed reactive compounds are reacted with a corresponding reactive material for eliminating the reactive compounds from the gas to be purified.
