ABSTRACT:
The present invention is a process for the liquefaction of hydrogen which utilizes a dense fluid expander and neon as a precoolant refrigerant. In the process, a two phase mixture containing about 85-90% liquid of greater than 95% para-hydrogen is produced in a dense fluid expander. Most of the refrigeration for liquefaction is supplied by a neon refrigeration system, consisting of a centrifugal compressor, heat exchangers and one or more stages of neon expansion. As an option, further refrigeration may be supplied utilizing liquid nitrogen as another precoolant.
