RECOVERY OF NEON AND HELIUM FROM AIR BY ADSORPTION AND CLOSED CYCLE HELIUM REFRIGERATION

摘要

A method and installation for the separation of neon and helium mixtures in which the neon is condensed from the mixture at a temperature below 25 DEG K, the uncondensed neon is adsorbed from the mixture at a temperature between 22 DEG K and the critical-point temperature of helium, and a helium-cooling cycle is used to abstract heat from the mixture.
