CRYOGENIC RECTIFICATION SYSTEM FOR NEON PRODUCTION

摘要

A cryogenic rectification system employing a phase separator (30) , which may include one or more trays (32), in conjunction with a double column air separation plant, wherein some shelf liquid is subcooled and phase separated to produce crude neon vapor (5), and the remaining liquid (34) is used to reflux the lower pressure column (21) of the double column plant .
